Boasting RGB LED integration on the pump head and both of its 120mm fans, the Corsair Hydro Series H100i RGB Platinum SE looks like a high-end cooler. But does it perform well?

Well, you probably already know the answer, as it sits on the top spot on this list. Truth be told, the H100i is incredibly good at keeping the CPU temperatures low and staying quiet in the process, even under heavier loads. But that’s not all.

While other offerings from Corsair features limited RGB lighting, Corsair goes all out with the H100i Platinum SE and offers a full suite of RGB LEDs to really give you the opportunity to customize everything to your liking. To control the RGB lights, Corsair provides their iCUE software.

With this software, you’ll easily be able to change the color of the lights to match the rest of your build, as well as monitor the fans and pump. With this amount of RGB, the H100i is definitely an enthusiast-focused AIO. What makes this cooler the “special edition” model is the striking white paint job on the pump, radiator, and matching hoses.

Coming at a premium price, the H100i is the most expensive water cooler on this list. The big question is: is it worth the money?

For starters, It comes with a 5-year warranty, one of the best in the business. It is only topped by NZXT, who offer 6-year warranty for their AIO liquid coolers.

On top of that, the Hydro Series H100i boasts some high-quality components, as you would expect at that price point. Corsair’s signature chunky pump design is incredibly sturdy, and allows for a 90-degree swivel of the hoses to aid in installation. The cooling plate is made of copper and milled totally smooth. Corsair took the liberty of applying the thermal paste so you don’t have to worry about getting messy.

This Corsair cooler is compatible with basically every modern processor, even the Threadripper platform. You’ll have support for the Intel LGA 1200, 1150, 1151, 1155, 1156, 1366, 2011, and 2066. AMD support includes the AMD AM4, AM3, AM2, sTRX4, and TR4.

Performance-wise, the H100i doesn’t disappoint as well. In a test performed on an Intel I7-7700K, it outperformed the ThermalTake Floe Riing 240 by 6°C, the Alphacool Eisbaer 360mm cooler by 1°C and even the be quiet! Silent loop 360 by 10°C under load.

Overall, the Corsair Hydro Series H100i RGB Platinum SE is an incredible cooler. It’s one of the best 240mm AIO in terms of cooling performance, easily beating some of the larger, 360mm coolers. On top of that, the Platinum SE package makes this Corsair AIO the most visually appealing cooler on the list – the stunning white finish is breathtaking, and certainly differentiates it from most other coolers on the market. In short, if budget is not an issue for you, it doesn’t get much better than this in the 240mm category.

2. Arctic Liquid Freezer II 240

Radiator Dimensions: 277 x 120 x 38mm / 10.9 x 4.7 x 1.5” | Fans Dimensions: 120 x 120 x 25mm / 4.7 x 4.7 x 1” | Fan Speed: 200 ~ 1800 RPM (PWM) | Noise Volume: Up to 35 dBA | Warranty: 2 years

Arctic Liquid Freezer II 240REASONS TO BUY

  • Superior cooling capabilities
  • Impeccable build quality
  • Thicker rad for more efficiency
  • Great price
  • Quiet

REASONS TO AVOID

  • No RGB lighting
  • Only 2-year warranty

Our Rating:   9.8/10

In a bold aesthetic move, the Arctic Liquid Freezer II 240 totally forgoes RGB implementation in favor of raw performance. This proves to be a winning move, as the Arctic Liquid Freezer II 240 claims a second spot on this list.

While many AIO coolers offer some form of the trendy RGB LEDs that bedeck many modern computer towers, this AIO cooler from Arctic doesn’t feature any lights at all. Of course, this is still a nice-looking cooler. Its glossy black finish is accentuated by the silver Arctic logo printed on the pump head and in the center of both of the 120mm fans. The silver motif extends to the hoses, where the braided nylon is printed with silver stripes. It’s an industrial approach to a design space that typically trends toward bright and flashy.

Arctic’s commitment to cooling excellence extends to the build quality of the Liquid Freezer II. The cooler features a radiator that’s 38mm thick, slightly thicker than most other radiators. This allows Arctic to pump more water through the cooler, improving cooling efficiency with its multi-channel water flow.

Additionally, its hoses are fiber-reinforced to protect against kinking, leakage, and evaporation. The hoses are made of EPDM material, an industrial-strength rubber. There’s even a small 40mm fan on top of the pump. Arctic really pulled out all the stops to ensure the Liquid Freezer II’s supremacy.

As far as compatibility goes, the Arctic Liquid Freezer II 240 interfaces with the Intel LGA 1150, 1151, 1155, 1156, 1200, the square ILM 2011-3, and the square ILM 2066. It’s also compatible with the AMD AM4. This is a somewhat limited amount of socket support when compared to others on the list, but it shouldn’t be an issue for a majority of people using modern CPUs.

Performance is the reason to consider the Arctic Liquid Freezer II 240, where it’s the king of the 240mm class. In a test performed on an Intel I9-9900K clocked at 3.8 GHZ, the machine only rose 26.2°C, one of the best in its class.

For comparison, the Corsair Hydro Series H100i RGB Platinum S and the Cooler Master MasterLiquid ML240L each saw a 32.4°C rise in temperature in the same test. When overclocked to 4.7 GHZ, the Arctic Liquid Freezer II 240 continued to impress, only seeing a change in temperature of 49.2°C. That was almost 10 degrees better than the previously mentioned Corsair and Cooler Master.

The Arctic Liquid Freezer II 240 is one of the absolute best water coolers on the market when it comes to raw cooling performance, but it’s also one of the quietest, with only 41.2 dBA under load. You won’t be disappointed in this AIO’s performance, and you’ll be able to overclock with confidence.

All in all, this is the ideal cooler for someone looking to push their machine to the limit, but really needs to the 240mm form factor to fit in their tower. The Arctic Liquid Freezer II 240 AIO is a robust performer and stays quiet while it works. The build quality of this cooler is also something to write home about; it’s simply among the best in its class. Tying it all together is the modest and really fair price.

3. EVGA CLC 240mm AlO RGB

Radiator Dimensions: 276 x 122 x 28mm / 10.9 x 4.8 x 1.1” | Fans Dimensions: 120 x 120 x 25mm / 4.7 x 4.7 x 1” | Fan Speed: 500 ~ 2400 RPM (PWM) | Noise Volume: 16 – 40 dBA | Warranty: 5 years

EVGA CLC 240mm AlO RGBREASONS TO BUY

  • Great cooling capabilities
  • Intuitive software
  • 5-year warranty
  • Supports large variety of CPUs
  • Fairly priced
  • High quality construction

REASONS TO AVOID

  • Slightly louder
  • RGB only on the pump head

Our Rating:   9.7/10

Dressed in glossy black paint, the EVGA CLC 240mm AlO RGB features RGB LED lighting on its pump head for some extra flair. It’s not the most extensive RGB implementation in the 240mm class, but this is still an attractive AIO cooler.

While some other AIO coolers in its class boast a complete RGB LED setup that extends to their fan blades, the EVGA CLC 240mm AlO RGB only features it on its pump head. Unfortunately, you won’t be able to install your own RGB fans either. However, the glossy finish on the pump head, radiator, and hose sleeves make this a great looking cooler despite the limited amount of RGB.

Of course, the allure of RGB is the ability to customize it, and for that EVGA provides Flow Control software. With the software, you can change the colors of the RGB lights as well as control the fan speed and pump output. From the software, you’ll also be able to glean valuable information such as fan RPM and coolant temperature. Flow Control really does give you a lot of control over your AIO cooler.

The EVGA CLC 240mm AlO RGB supports a host of modern processors, leaving no major player out in the cold. You’ll be all set if you’re running an Intel LGA 2066, 2011, 2011-v3, 1200, 1150, 1151, 1155, 1156, or 1366; or an AMD AM2, AM3, AM4, FM1, FM2, or TR4.

The build quality of this EVGA AIO is respectable. The hoses are covered in a nylon satin braiding, providing a high-quality look and feel as well as functionally reducing kinking and leakage. Unfortunately, the pre-applied thermal compound feels chalky and ineffective. You might need to grab a tube for yourself.

The cooling performance of the EVGA CLC AIO is very impressive, and it outperforms many formidable coolers in the 240mm class.

In one test using an Intel I7 5930k clocked at 4.2 GHZ, the EVGA cooled the CPU to 31°C over ambient temperatures, 11°C better than our top-rated Arctic Liquid Freezer 240 and 18°C better than the Gamer Storm Captain 240. While it’s not the quietest of the bunch, it’s not a terribly noisy cooler either, but the noise levels did keep it from earning the top spot on the list.

Coming in at a reasonable price, this cooler is definitely good value proposition. EVGA also offers a five-year warranty, one of the best in the AIO cooler market.

All in all, there’s a lot to like about the EVGA CLC 240mm AlO RGB. While its RGB LED implementation is a little sparse in comparison to some competitors, it’s a very nice looking AIO cooler. It also offers some of the best cooling capabilities in its class, and comes in at a price right around what you would expect to pay for a 240mm cooler. It rounds out the top three on our list and comes highly recommended.

MSI MAG CORELIQUID 240RREASONS TO BUY

  • Easy to install
  • Vibrant RGB lighting
  • 3-year warranty
  • Great cooling capabilities
  • Very quiet
  • Comes with a smart controller

REASONS TO AVOID

  • Higher price

Our Rating:   9.6/10

The MSI MAG CORELIQUID 240R is a stylish cooler that boasts a unique rotating pump head and addressable RGB implementation. This MSI AIO cooler also offers solid cooling performance at a very affordable price.

In the box you’ll find two ARGB PWM 120mm fans, smart fan controller, fan mounting screws, and the installation guide. You’ll have everything you need to get it setup in short order.

Part of the allure of AIO cooling is the ease of installation, and in that the CoreLiquid 240R is no different than many others. Installing this cooler is quite simple, only requiring a few screws to mount the pump and fans. Most PC-builders will have no issues getting this AIO up and running in about 10 minutes.

This cooler is highly compatible and interfaces with most modern processors. It’s compatible with Intel LGA 1150, 1151, 1155, 1156, 1200, 1366, 2011, 2011-3, and 2066 sockets. AMD support includes AMD AM4, FM2+, FM2, FM1, AM3+, AM3, AM2+, and AM2.

As mentioned, the MSI MAG CORELIQUID 240R is one good-looking cooler. It boasts addressable RGB LED implementation on the fan blades and on the MSI logo printed on the pump head. It’s very tastefully done, and even those who are averse to RGB will appreciate the splash of color it provides. Controlling the RGB lights is done with the included remote or your motherboard. The rest of the cooler is the usual glossy black, which catches the lights well and looks fantastic.

This MSI cooler boasts a few unique features that set it apart from other coolers on the list. Its pump head rotates 270 degrees, allowing you to mount the cold plate however you need to, while keeping the pump upright.

Additionally, its pump is built into the radiator. This innovation allows for two things: better sound dampening so the pump runs quieter and an increase in longevity by keeping the pump away from the heat source. The radiator also features a split pathway design to allow for more efficient heat transfer than traditional radiators. These unique features make the CoreLiquid 240R an intriguing cooler.

As far as performance goes, this AIO performs on par with coolers. It doesn’t offer best-in-class cooling, but it keeps pace just fine. One test on a Ryzen 3 3600 overclocked at 4.1 GHZ showed the CoreLiquid 240R cooling the system to 39°C at idle and 45°C under load. This test demonstrates that this cooler is suitable for an overclocked machine and will capably handle stress.

While its cooling performance was decent, the best quality of the CoreLiquid 240R is how quiet it runs. On average, it’s 5 decibels quieter than other coolers in its class. The embedded radiator is no doubt to thank for that.

Overall, this MSI AIO represents good value. The MSI MAG CORELIQUID 240R offers good performance, quality styling, and some unique features that set it apart from other coolers. There’s a lot to like about it, and nothing at all that sticks out in a bad way – it represents a great balance of price, noise dampening, RGB implementation, and overall cooling performance.

5. Cooler Master MasterLiquid ML240L RGB V2

Radiator Dimensions: 277 x 120 x 27mm / 10.9 x 4.7 x 1.1” | Fans Dimensions: 120 x 120 x 25mm / 4.7 x 4.7 x 1” | Fan Speed: 650 ~ 2000 RPM (PWM) ± 10% | Noise Volume: 6 ~ 30 dBA | Warranty: 2 years

Cooler Master MasterLiquid ML240L RGB V2REASONS TO BUY

  • Awesome aesthetics
  • Beautiful RGB
  • Great cooling capabilities
  • Incredible price/performance ratio
  • Supports large variety of CPUs

REASONS TO AVOID

  • Only 2-year warranty
  • Slightly louder

Our Rating:   9.5/10

The Cooler Master MasterLiquid ML240L represents one of the best deals on the market, coming it at the astonishingly low price. If you’re looking to add a sleek, stylish cooler with excellent performance without breaking the bank, you’ve found your perfect cooler. It’s just edged out for the top spot on the list due to its slightly louder fans.

This Cooler Master is a good looking cooler, boasting RGB LEDs on the pump head and on both of its 120mm fans. You can customize these lights with the included controller or with a compatible motherboard. Other aesthetic features include a matte black paint job on the pump head and braided nylon sleeves for the hoses, which also serve to eliminate kinking and prevent leakage. It certainly looks like more of enthusiast-level cooler due to its RGB implementation.

Installation of the ML240L is pretty straightforward. Both fans even come preinstalled in their housing, eliminating the potential headache of pre-mounting the fans. The only thing setting installation of this cooler apart from others is that you’ll be applying the thermal paste yourself, but that allows the paste to adhere to the cold plate more effectively.

New PC builders shouldn’t fear the application of thermal paste, as applying it yourself ensures a stronger bond and more efficient heat management. You’ll see later in the list how pre-applied paste can become an issue.

This AIO features support for almost all modern processors, including the Intel LGA 2066, 2011-v3, 2011, LGA1200, 1151, 1150, 1156, and 1155. As for AMD, you’ll find support for the AMD AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, and FM1. It also supports the TR4 processor, but the mount for that is not included.

Performance-wise, you’ll be pleased to find the Cooler Master MasterLiquid ML240L scores near the top of the 240mm class in both raw cooling ability and in noise dampening. One test on an Intel i7-5930k clocked at 4.2 GHz showed the Cooler Master keeping the PC at 37° C over ambient with both fans at maximum RPM.

This was 5°C better than the Arctic Liquid Freezer II and 12°C better than the Gamer Storm Captain 240. This means that the Cooler Master is ready to take on powerful machines, and is one of the best choices for doing so. Unfortunately, it wasn’t as quiet as the Arctic.

Of course, this cooler is bargain-priced and comes with a two-year warranty. Though the warranty is a bit shorter than you’d expect, the price is an absolute steal. It’s on par with many coolers in the same catagory and offers a lot more in the way of cooling performance.

All in all, the Cooler Master MasterLiquid ML240L is amazing value for an AIO cooler. You’ll be hard pressed to find this level of cooling performance at a cheaper price. Of course, it also boasts the added bonus of RGB LED integration, further elevating its value. All things considered, this is probably the best budget AIO cooler currently available on the market.

6. Thermaltake Floe Riing RGB 240 TT Premium Edition

Radiator Dimensions: 270 x 120 x 27mm / 10.6 x 4.7 x 1.1” | Fans Dimensions: 120 x 120 x 25mm / 4.7 x 4.7 x 1” | Fan Speed: 500 ~ 1400 RPM | Noise Volume: 19.8 – 24.7 dBA | Warranty: 2 years

Thermaltake Floe Riing RGB 240 TT Premium EditionREASONS TO BUY

  • High-performing cooler
  • Arguably the best RGB lighting
  • Software and iOS/Android app for control
  • Quality and durable build
  • Quiet

REASONS TO AVOID

  • only a 2-year warranty
  • Premium price
  • Shorter hoses

Our Rating:   9.4/10

Thermaltake was one of the first companies embrace the RGB trend in computer building, and their Floe Riing RGB 240 TT Premium Edition shows they don’t plan on stopping anytime soon.

The Thermaltake Floe Riing RGB 240 TT Premium Edition boasts an exquisite amount of RGB LED implementation, as both of the 120mm fans and the pump head are covered in them. If that’s your thing, then you’ll love this AIO cooler, as no one does RGB better than Thermaltake.

You’ll also have software to control the lighting and even an IOS and Android phone app. With all of this RGB and customization, this is definitely an enthusiast-focused cooler.

Unfortunately, Thermaltake’s software is rather lackluster. You can adjust the lighting and fan speed, but changing profiles requires a system restart, so modifying your cooling settings on the fly is impossible. Additionally, the smartphone app only controls the RGB lights and not the fans or pump.

Of course, what’s disappointing about this AIO is the high price point –  it’s one of the most expensive coolers in its class.

On the bright side, installation of the Floe Riing is very simple, in line with many other coolers. It basically just bolts into place. Thermaltake has even gone ahead and applied the thermal paste for you. The only difficulty one might encounter during installation of this cooler is due to the shorter radiator pump pipes, meaning it might be a two-person job requiring someone to hold it in place while you bolt it down.

Despite the software shortcomings, the performance of the Thermaltake Floe Riing RGB 240 TT Premium Edition is quite impressive. A test performed on an Intel I7 3930K revealed that the Flow Riing is amongst the best coolers in its class and even took on a slightly larger 280mm cooler.

At 3.8 GHZ clock speed, the Floe Riing cooled the CPU to only 5.5°C over ambient at idle and 38.6°C over ambient under load. When the machine was overclocked to 4.4 GHZ, the Floe Riing showed its prowess and posted a change in temperature of 16.8°C at idle and a very impressive 40.5°C under load. All this means that the Thermaltake Floe Riing RGB 240 TT Premium Edition is a high-performing AIO cooler that can handle whatever comes its way.

While the price of this AIO is on the higher end for a 240mm cooler, you’ll be getting your money’s worth as far as performance goes. You’ll be able to safely overclock your machine and look stylish in the process, thanks to the RGB LEDs on the cooler’s fan blades and pump head.

While Thermaltake’s software support is pretty lackluster, you’ll have control over all aspects of the cooler. This is a great choice for an enthusiast with a bit of money to spend; you’ll simply love the RGB and will appreciate the Floe Riing’s performance.

ID-COOLING ZOOMFLOW 240X SnowREASONS TO BUY

  • Great looks
  • Budget friendly
  • Fabulous RGB lighting
  • Easy to install, universal fit
  • Decently quiet

REASONS TO AVOID

  • Not top-of-the-line performance
  • cable management is needed

Our Rating:   9.3/10

ID-COOLING flips the script with the ZOOMFLOW 240X Snow by offering it in a stark white, differentiating it from just about every AIO cooler out there, which are usually black.

Coming at a lower price than its peers, it’s much more budget-friendly than many of the other coolers on this list. It would be a good entry-level cooler for someone just getting into liquid cooling because of that. However, it does come with only a 2-year warranty, hurting the overall value of this AIO.

As far as processor support goes, the ZOOMFLOW basically runs the gamut. It’s compatible with the Intel LGA 2066, 2011, 1366, 1200, 1151, 1150, 1155, and 1156. Support for AMD processors include the TR4, AM4, FM2+, FM2, FM1, AM3+, AM3, AM2+, AM2.

Aesthetically, the ZoomFlow is quite striking. Unlike other AIO coolers, the Snow model is a bright white rather than matte black. This definitely sets it apart from other coolers, but it might not match the rest of your build. This cooler also comes decorated in addressable RGB LEDs on the 120mm fans and pump head. You’ll easily be able to color match them with the handy controller.

While looks and price are definitely the main draw of this AIO cooler, the build quality of the ZoomFlow 240X Snow is quite good. The hoses are reinforced and sleeved in white nylon so that they match the rest of the cooler. The radiator is made of solid aluminum and the cold plate is smooth copper, allowing for easy application of the included syringe of thermal paste. A tooth and ring system allows for incredibly easy bracket installation; the brackets will just twist right on to the pump head.

Performance-wise, the ZoomFlow is good, but not spectacular. In a test run on an I7 5930K running at 4.2 GHZ, the ZoomFlow outperformed the ID-COOLING DASHFLOW 240, posting an improvement of 3°C in temperature over ambient with maximum fan speed. Acoustically, the cooler also does a decent job dampening the sound, but it was outperformed by the DashFlow. Given the low price point, this is still quality performance.

Overall, the ZoomFlow 240X Snow is unique due to its bright white color and boasts respectable cooling performance at a bargain of a price. Its addressable RGB LEDs are striking and improve the value of this cooler, making it an attractive proposition for an enthusiast-level build.

All in all, you likely won’t be disappointed in the ZoomFlow if you don’t expect top-of-the-line performance and really enjoy the white paint job. It also is compatible with the Threadripper processor, which is notably difficult to find an AIO cooler for. This makes another great introductory-level cooler for those just getting started in water-cooling.

8. NZXT Kraken X53

Radiator Dimensions: 275 x 123 x 30mm / 10.8 x 4.8 x 1.2” | Fans Dimensions: 120 x 120 x 26mm / 4.7 x 4.7 x 1” | Fan Speed: 500 ~ 2000 RPM (PWM) | Noise Volume: 21 ~ 36 dBA | Warranty: 6 years

NZXT Kraken X53REASONS TO BUY

  • Good performance
  • High quality build
  • 6-year warranty
  • Beautiful aesthetics
  • Easy to customize
  • Runs fairly quiet

REASONS TO AVOID

  • Not the best-performing AIO
  • Higher price

Our Rating:   9.2/10

Featuring the incredibly stylish mirrored pump head like its 120mm cousin, the NZXT Kraken X53 is one of the most visually appealing 240mm coolers on the market. It also boasts relatively easy to manipulate RGB integration.

If you’re looking for a flashy cooler for your showy build, then the NZXT Kraken X53 might just be the perfect cooler for you. The mirrored pump head is like nothing else offered on an AIO cooler. It provides an “infinity mirror” style look and is ringed in RGB LEDs. It’s incredibly eye-catching and makes this cooler perhaps the best-looking 240mm AIO on the market. If you have a glass-windowed tower, this cooler is the perfect mate for it.

You can control the RGBs via NZXT’s CAM software. The CAM software is good at monitoring your setup, but disappointingly lacks fan control options. What could have been a big win for the Kraken X53 is instead rather middling.

Installation of the Kraken X53 is a relatively simple affair. Like many other coolers, you’ll first bolt down the radiator, then the backing plate, and finally the pump. However, you might run into an issue installing the fans, as they must be connected to the motherboard individually. On most other coolers, the fans are connected to the pump enclosure. NZXT pre-applied the thermal paste, so you won’t have to get messy with that.

The NZXT Kraken X53 offers middling performance. It’s not a world-beater by any means, but it will provide adequate cooling, even on an overclocked machine. It’s most comparable to the Corsair H115I RGB Pro XT, that retails for around $60 more than the Kraken.

They posted the same change in temperature at idle (6.5°C) while the Corsair was about one degree more efficient under load in a test performed on a stock I7 9700K. Acoustically, the Kraken was also found to have average metrics with a 36.8 dBA.

Average performance comes at an average price point, with the Kraken X53 coming at a bit higher price than you would have expected. But, NZXT offers a six-year warranty, the most robust warranty offered on the market.

As far as connectivity goes, the Kraken X53 is compatible with the Intel LGA 1151, 1150, 1155, 1156, 1200, 1366, 2011, 2011-3, and 2066. AMD support includes the AM4 and TR4, though Threadripper users will have to use a separate bracket that likely came with their processor.

While offering decent performance, the NZXT Kraken X53 is one of the most dazzling 240mm AIO coolers on the market. Its infinity mirror is eye-catching, incredibly unique, and sure to draw attention from some enthusiasts. While its performance is respectable, it’s far from world-beating, especially at this price point. If you’re not planning on overclocking your CPU, the X53 might be a perfect fit for you thanks to its looks, decent cooling capabilities and a best-in-class 6-year warranty.

Focused on mid-sized gaming builds, the Asus ROG STRIX LC 240 is a formidable AIO cooler that boasts RGB lighting on its pump head.

Aesthetically, the ROG Stix LC 240 isn’t doing anything out of the ordinary. Its flat black paint job is typical for AIO coolers, and its fans don’t feature RGB LEDs like many others in its class.

Enthusiasts will be disappointed in their exclusion, but the RGBs that decorate the pump head are very bright and high-quality. Additionally, the pump head also illuminates the “Republic of Gamers” logo for added swagger. You’ll be able to control the RGB lights with Asus’ Aura Sync technology.

The quality of this Asus cooler’s components is great. You’ll find the hoses have been reinforced and sleeved in black nylon to match the rest of the cooler. They’re also 38cm long, a bit longer than other coolers’ tubing. This should aid installation and allow you more freedom while you build.

Asus has further optimized the ROG STRIX LC 240’s fans. The 120mm fans are designed specifically for the ROG STRIX LC Series radiators and provided notable increases in air flow (81 CFM for the Asus versus the average of 71 CFM) and in static pressure.

The Asus ROG STRIX LC 240 is compatible with a wide range of modern processors. Just about everyone but older AMD users will be supported. This includes the Intel LGA 1150, 1151, 1152, 1155, 1156, 1366, 2011, 2011-3, and 2066. It also supports the AMD AM4 and TR4.

Installing the ROG STRIX LC 240 is a simple affair. Like most other AIO coolers, it’s as simple as picking the appropriate mounting block and fastening a few screws. Asus has even gone ahead and pre-applied your thermal paste. The only hiccup you might encounter is, if you’re an inexperienced PC builder, you might struggle to read to manual. The diagrams are a bit confusing, but a trip to YouTube will have things sorted out in short order.

The main drawback of this AIO cooler is its premium price and the lack of premium features to support it. As of today, there are just much better options available on the market.

Overall though, the Asus ROG STRIX LC 240 is a solid option in the 240mm class. It comes with some RGB LED implementation that’s easy to customize with included software, and boasts a very high build quality. Asus’ various optimizations do have some practical benefits and the fans are some of the best offered on a 240mm cooler. However, the premium price is not really justified by anything and you will be better off looking elsewhere, especially if you’re on a tight budget.

If you’re on a budget but looking for a quality cooler that doesn’t skimp out on some of the flashier features, you’ll love the ID-COOLING AURAFLOW X 240.

The AuraFlow X 240 can be had for a modest price at most online retailers, making it one of the cheapest 240mm AIO coolers on the market. However, it still offers a full suite of RGB compatibility at this low price. It boasts the trendy lights on both of its 120mm fans and on its pump head, where it illuminates the ID-COOLING logo. Unfortunately, the lights on this AIO aren’t as luminous as the lights on some other coolers in its class.

As far as compatibility goes, the AuraFlow X 240 is able to interface with virtually every modern processor, including Threadrippers. Its socket support includes the Intel LGA 2066, 2011, 1366, 1151, 1150, 1155, 1156, and 1200. On the AMD side of things, you’ll find support for the TR4, AM4 FM2+, FM2, FM1, AM3+, AM3, AM2+, and AM2.

The build quality of the AuraFlow is better than you’d expect to find on a budget AIO. It features a large satin-finished copper cooling plate that’s been milled smooth. Its radiator is completely made of aluminum and features a dual-fin design that optimizes water flow and provides very efficient cooling.

Its fans also come enclosed in a noise-dampening rubber housing to help keep the cooler quiet when they’re spinning at maximum RPM. Lastly, the hoses are reinforced and sleeved in matte black nylon.

Installation of the AuraFlow X 240 is almost identical to any other AIO cooler. With a few screws, you’ll be water-cooling in around 10 minutes time. The only thing to note regarding the installation is the 90-degree swivel of the tubing. This makes it even easier to configure inside your tower.

Unfortunately, the budget AuraFlow X 240 doesn’t keep up in the cooling performance department. It’s outdone in all metrics by its ZoomFlow counterpart and lags behind many of the other popular 240mm coolers on the market. It’s even quite loud despite its poor performance metrics.

All in all, the ID-COOLING AURAFLOW X 240 is good-looking budget 240mm AIO cooler. At the low price, you’ll still get all the benefits of a 240mm radiator and a complete RGB package. This makes it a great introductory cooler for someone who doesn’t need the high-performance of more expensive coolers, but still wants to hop on the water-cooling bandwagon. For the price, it certainly looks great, and it’s compatible with just about every modern socket type.
