Here at G15tools we’re all about PC Gaming and we like to take a critical look at the best products on offer to make sure you get the very best bang for your buck. This means we sometimes review products we wouldn’t really recommend.

With the popularity of liquid coolers and their thermally efficient nature, we have seen a growing trend of 120mm AIOs and AIO CPU Coolers. These AIOs and Coolers are specifically designed to work with a 120mm radiator and keep the CPU and other components cool – there is no need to go through the hassle of installing a dedicated water cooling system.

CPU cooling is an underrated part of the PC build. Buyers often forget to consider cooling when they build their own rig, which often leads to system crashes, overheating and other headaches. This has been a slow slow process in the computer hardware industry, with only a handful of companies investing in CPU cooling in the past decade. In fact, in my opinion, the best CPU coolers of all time are the XSPC AX AIO. These coolers are not only great in performance but also in form factor, featuring a very stealthy and compact design, making them a great choice in a compact PC build..

If you consider it in comparison to coolers with bigger form factors, which you should due of its performance, this cooler represents excellent value.

The ML120R’s RGB integration is quite important in terms of aesthetics. All major motherboards are compatible with the RGB LEDs, which cover both fans and the pump head. The RGB lights may also be controlled with the supplied controller. Aside from the bright lights, the cooler is coated a glossy black to reflect light and contribute to the RGB experience.

Our score is 9.6 out of ten.

The Corsair Hydro Series H80i v2 is designed to compete with coolers that have considerably bigger form factors. This 120mm AIO definitely punches above its weight class, with to its extra-large radiator and dual-fan setup. You’ll adore this Corsair cooler if you don’t have the space but need the cooling performance.

Unfortunately, you won’t be able to use RGB LEDs, but for many people, this won’t be a deal breaker. This cooler comes at a premium price, and you’ll note that it’s on the upper end for a cooler of this size. However, Corsair provides a 5-year guarantee in the event that anything goes wrong.

The size and quality of the Corsair Hydro Series H80i v2’s components, particularly the radiator and hoses, set it apart from comparable 120mm coolers. The radiator is 49mm thick, which is considerably thicker than comparable 120mm AIO coolers’ radiators. This enables more effective heat transmission as well as improved cooling capabilities. The hefty components of this cooler are what make it so unique, and they’re also what make it such a fantastic deal despite the increased price.

Furthermore, the hoses are considerably thicker than those found on most coolers of this size, and are comparable to those found on a 280mm cooler. It also has a dual-fan configuration for faster heat dissipation. Of course, the quality of these components is excellent and commensurate with their high price.

If you’re using a modern computer, you’ll have no problems with compatibility. This cooler is compatible with Intel LGA 1200, 115X, 1366, 2011, and 2066 processors, as well as AMD AM4, AM3, and AM2. The AMD TR4 is also supported, however you’ll need to buy a separate bracket from Corsair.

The Corsair is very easy to set up. It comes with all of the standard mounting brackets and thumbscrews, and the thermal paste is applied for you. The only snag you may have is if you’re using a TR4 socket and haven’t purchased the additional mounting bracket. Aside from that, due to the easy-to-read instructions, this cooler is extremely simple to set up.

The Corsair Hydro Series H80i v2 meets its objective of matching the cooling capabilities of bigger coolers in terms of performance. In one test, the Corsair kept up exactly with the Silverstone TD 02 Slim, a 240mm AIO cooler, producing identical figures at idle and under load. When overclocked, the Corsair performs even better than its competitors, outperforming the 120mm competition.

One disadvantage of this cooler is that it lacks RGB lighting. It does, however, include the standard Corsair LED light on the pump head and is Corsair Link software compatible. The absence of RGB at this price range may be seen as a significant disadvantage, since most enthusiasts with money to spend will want to personalize their builds and want components to match the rest of their RGB setup.

Overall, the Corsair Hydro Series H80i v2 is one of the best 120mm AIO coolers available today. Due to its over-sized radiator and tubing, it keeps up with many bigger coolers. While the Corsair isn’t cheap, it’s a fantastic bargain for someone who needs a powerful computer but doesn’t have a lot of room in their tower.

4. Asus ROG Strix LC 120

Radiator Dimensions: 150 x 121 x 27mm / 5.9 x 4.8 x 1.1” | Fan Dimensions: 120 x 120 x 25mm / 4.7 x 4.7 x 1” | Fan Speed: 800 – 2500 RPM +/- 10% | Noise Level: Up to 37.6 dBA | Warranty: 5 years


  • Excellent cooling capacity
  • Construction of high grade
  • Warranty period: 5 years
  • Installation is simple.
  • Hoses with nylon sleeves
  • RGB lighting that is elegant


Our score is 9.5 out of ten.

The Asus ROG Strix LC 120 is a powerful, high-performance AIO with RGB lighting on the pump head that may be customized. It has a sleek, contemporary design and excellent cooling capabilities, but it is a little too noisy to win the top position as the best 120mm AIO cooler.

As is customary for the ROG product line, this cooler is not cheap. However, considering its speed and RGB integration, it is well worth the money. To be honest, it’s a little cheaper than the MasterLiquid ML120R RGB, which is very expensive. In another area, Asus outperforms CoolerMaster with a 5-year guarantee.

The aesthetics of the Asus ROG Strix LC 120 are excellent. The RGB lights are done extremely tastefully and just adorn the pump head. The tabbed shape of the pump head, which gives it the appearance of a gear, is another intriguing element. It’s a great touch that emphasizes the AIO cooler’s toughness.

When the RGB lights are switched on, the Republic of Gamers emblem is printed on the pump head and glows. The remaining parts are painted in a glossy black finish. The paint work is beautiful and compliments the RGB lights by catching and reflecting light.

This ASUS AIO is excellent in terms of quality. The cold plate is composed of highly conductive copper, while the pump is entirely built of aluminum. Its hoses are nylon-sleeved and very robust. The Strix LC 120’s excellence will leave you speechless.

The Asus ROG Strix LC 120 is extremely simple to set up and takes just around 10 minutes. It mounts with a few thumbscrews, much like many other AIO coolers. The main drawbacks of this cooler are that you must apply the thermal paste manually and that AMD AM4 users must keep the backplate in place. While the use of thermal paste makes installation a little more difficult than with some other coolers on the market, it’s still a simple procedure.

If you’re using a recent CPU, you’ll be OK in terms of socket compatibility. Intel LGA 115x, 1200, 1366, 2011, 2011-V3, and 2066 are supported. The AM4 and TR4 processors are supported by AMD, which is noteworthy given that several of the mentioned 120mm AIO coolers do not support the Threadripper architecture. This is the cooler to get if you’re running a TR4.

In terms of performance, the Asus ROG Strix LC 120 outperforms most other 120mm AIO coolers. This cooler even stacked well against the Lian Li Galahad, a 360mm cooler, in one test. Under normal conditions, the Asus cooler was only 3-degrees warmer than the Galahad, and 4-degrees warmer when overclocked. That’s quite a feat for a cooler with such a tiny footprint. Unfortunately, the fan was working overtime and was very noisy throughout these testing.

Overall, this cooler has good aesthetics and performance, however it is expensive when compared to other 120mm coolers. However, when it comes to performance, it is generally equivalent to bigger coolers, making it a good deal. It falls just shy of the Cooler Master MasterLiquid ML120R RGB’s extremely high bar. If you have a powerful computer but don’t have enough room for a bigger cooler, the Asus ROG Strix LC 120 AIO cooler is a great option.

The TH120 has a very low profile, which makes it suitable for a smaller tower. Despite its little stature, this cooler delivers a powerful punch. In stress testing and at idle, it has been proven to function as well as much bigger coolers. Furthermore, the single fan is almost quiet, which is unusual for such a tiny cooler.

The TH120 is likewise a high-quality device. With the exception of the length of the hoses, there are practically no concerns. They’re a touch shorter than you’d want, but the components are of excellent quality, particularly the extremely silent TT-1225 fan.

The Thermaltake TH120 is an amazing steal when it comes to pricing. It’s just $66.99 and comes with a 3-year guarantee from the manufacturer.

Overall, the Thermaltake 120mm AIO is a fantastic cooler. If RGB LEDs are your thing, you won’t find a cooler that supports them better. You’ll also have a lot of choices for customizing those lights.

This cooler is also very compatible with nearly all contemporary plugs and is quite simple to set up. Its cooling performance is particularly remarkable, as it competes with some bigger coolers at a fraction of the cost, all while remaining silent.

Cooler Master MasterLiquid LC120L V2 RGBREASONS TO PURCHASE

  • Excellent cooling capacity
  • The cost is reasonable.
  • Fantastic RGB lights
  • Installation time is minimal.
  • Simply plug in and play
  • It’s quite quiet.


  • Only a two-year warranty is offered.
  • Not recommended for extreme overclocking.

Our score is 9.3 out of ten.

On all fronts, the Cooler Master MasterLiquid LC120L RGB V2 is an appealing cooler. It has several of the RGB LED features that set it apart from the competition, while still delivering cooling performance on par with other bigger coolers. Although it isn’t the finest in its class, its reduced price makes it an appealing deal.

Installing the Cooler Master MasterLiquid LC120L RGB V2 is simple, as it is with many other AIO coolers. It just takes a few screws to get this cooler up and running, and PC builders of all abilities will have no trouble doing so.

Cooler Master also provides a tiny tube of thermal paste, rather than just a scattering, to make installation even simpler. You’ll have greater control over the application of the paste, and it won’t be as messy. Aside from that, there’s the typical selection of cooler installation equipment, such as mounting brackets for Intel and AMD sockets.

This Cooler Master is compatible with the majority of existing sockets. Intel LGA 2066, 2011 v3, 2011, 1200, 1151, 1150, 1156, 1155, and 1366 are all supported. On the AMD side, AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, and FM1 are all supported.

The Cooler Master MasterLiquid LC120E RGB features highly-customizable RGB lights set against a beautiful matte black paintjob in terms of appearance. This is a really appealing AIO cooler that would look fantastic in any computer.

The RGB lights on the pump and fan may be controlled with the supplied controller or with an RGB-compatible motherboard. If RGB isn’t your style, the matte surface of this cooler makes it appear stylish even when the lights are turned off.

This Cooler Master 120mm AIO’s compact form factor makes it an excellent match for thin tower designs or any system where space is limited. Despite its tiny size and 120mm radiator, this cooler can compete with bigger coolers and offer comparable cooling efficiency as its 240mm counterpart. It will, however, get very loud under high loads. Unlike the TH120, the fan on this cooler is loud since it runs at a significantly higher RPM to ensure optimum efficiency.

When it comes to the MasterLiquid LC120L’s pricing, this cooler is a steal. For less money, you’ll be hard pushed to find a cooler with more RGB and this degree of cooling performance. However, this AIO’s guarantee is just two years, compared to Corsair’s or ASUS’s five-year warranties. For others, this may be a deal-breaker, since the added peace of mind is certainly worth a few bucks extra.

The Cooler Master MasterLiquid LC120L RGB V2 is a good choice overall. It features some of the finest RGB integration in the 120mm AIO market, as well as excellent performance metrics and compatibility with the majority of current computers. Despite this, the warranty is a few years less than you would want. Overall, though, this cooler has a lot to recommend it.

We give it a 9.2 out of 10 rating.

The AIO D-RGB is a good choice if you’re searching for a high-quality all-in-one water cooler at a reasonable price. Not only does it look spectacular with RGB fans and a CPU block, but it also provides remarkable endurance thanks to strengthened tubing and diamond-cut rotary fittings.

The simplicity of installation is one of the cooler’s most remarkable characteristics. Right out of the box, you’ll have everything you need to set up the AIO D-RGB. You won’t even need a screwdriver since EK provides one with the mounting bracket installation.

It also has a mount that may be used with both AMD and Intel sockets. Setting up this cooler is extremely simple, and the included instructions ensure that anybody, even those with no experience constructing PCs, can have it up and running in no time.

The EK AIO D-RGB, as previously stated, is compatible with both AMD and Intel sockets. The AMD AM4 processor is supported, as well as a variety of Intel LGA sockets, including the 115X, 1200, 2011, 2011-3, and 2066. A single mount is also required for the universal radiator.

All of the RGB lights on this AIO cooler will satisfy the enthusiast audience. These stunning lights can be seen on both the EK-Vardar S fan blades and the CPU block. The RGB settings may be simply controlled through your motherboard or a separate controller. The RGB lights are of excellent quality and have diffusers, allowing the colors to mix nicely.

In terms of build quality, the EK AIO D-RGB is exceptional. You won’t have to worry about leaks since the rubber tubing is strengthened, sleeved, and equipped with an aluminum cap. Even tight towers will be able to accept this EK cooler and its compact footprint thanks to the diamond-cut rotary connections, which allow for some adjustability during installation. EK also provides a five-year guarantee in case anything goes wrong.

The smaller 120mm radiator won’t be able to cool bigger and more powerful computers, but it will significantly increase performance over an air-cooled system if you have a smaller build. Its performance is mediocre for a 120mm cooler, and you won’t be overclocking or doing other demanding tasks with it.

Overall, this is a fantastic AIO water cooler choice. It has a compact footprint, so it will fit in most towers, and its components are of excellent quality, so it will last a long time. A 5-year guarantee is also provided, which is a nice touch. In general, the EK AIO D-RGB is an excellent buy.

There are, however, a few superior alternatives available. Some provide more RGB, while others provide greater performance and allow for overclocking. Despite this, there’s a lot to enjoy about this cooler, so you won’t be disappointed if you choose it.

Corsair Hydro Series H60 (No. 8)

Radiator: 157 x 120 x 27mm/6.2 x 4.7 x 1.1” | Fan: 120 x 120 x 25mm/4.7 x 4.7 x 1” | Fan Speed: 1700 RPM | Noise Volume: Up to 28.3 dBA | Warranty: 5 years

Corsair Hydro Series H60REASONS TO PURCHASE

  • Extremely quiet
  • Excellent cooling properties
  • High-quality construction
  • Warranty period: 5 years
  • Installation is simple.
  • a reasonable price


  • There is no RGB lighting.
  • Corsair’s Link software isn’t supported.
  • Not as potent as other options

Our score is 9.1 out of ten.

The all-black Corsair Hydro Series H60 is a majestic machine. This all-in-one cooler gets high ratings for performance without breaking the budget, thanks to its high-density radiator and near-silent fan.

The advantage of all-in-one systems is their ease of installation, and the Corsair Hydro Series H60 is no exception. It, like many others, has a tool-free installation, so it may go directly from the box to your computer. The mounting kit, which is compatible with many contemporary CPUs, and the 120mm fan are also included in the package.

Most contemporary sockets, including AMD AM4, AM3, and AM2, are compatible with the H60. It is compatible with the 1200, 1150, 1151, 1155, 1156, 1366, 2011, and 2066 sockets from Intel.

The silent operation of the Corsair Hydro Series H60’s fan and pump is the most apparent feature. The cooler seems completely quiet while sat at a desk with the tower closed off, particularly when the fan is set to the lowest level. It’s easy to increase the fan speed if you need additional power. Even when the fan speed increases, it remains virtually imperceptible.

Despite the quiet, the Corsair is still working hard and providing excellent cooling, both at idle and under higher loads. This is due to the high-density radiator’s IP32 certification, which means it’s dust and water resistant. In addition, the hoses of the Corsair Hydro Series H60 are rubber-coated and kink-resistant. Other hoses have a nylon covering that looks better, but Corsair is focused on keeping costs low here.

This cooler is priced in the middle, thus it lacks the RGB LEDs that more costly models have. For those wanting to color-match their cooler with the rest of their build, this may be a letdown. Another small disappointment is the Corsair branding on the pump, which has a glaring white LED light that cannot be turned off when the cooler is switched on.

The Corsair H60 does not support Corsair Link, thus you’ll have to set the cooler via BIOS. Given the AIO’s price, this is a little disappointment. The Corsair Hydro Series H60 is a fantastic all-in-one cooler, despite the absence of showy RGB. It has excellent cooling capabilities in a compact package and is compatible with a wide range of contemporary computers.

The mid-range pricing is appealing to those who aren’t seeking to spend a lot of money and are willing to put up with a less-than-stellar looking cooler. Should something go wrong with it, Corsair also provides a 5-year guarantee. Overall, there are few faults with this all-in-one cooler, and the performance and quality are excellent.

The NZXT Kraken M22 is the most visually appealing of the AIO coolers on our list. Its pump has a “infinity RGB” design that is really stunning. Is this cooler, on the other hand, all show and no substance?

First and foremost, this cooler’s RGB design is stunning. When the RGB LEDs on the pump are turned on, they create a “infinity mirror” effect. This is without a doubt the most attractive 120mm AIO cooler on the market. The RGBs are completely programmable, and they can even be set to change color depending on temperature, something no other 120mm cooler on the list can accomplish.

When it comes to software, the Kraken M22 is compatible with NZXT Cam. This program allows you to change the RPM of the fan as well as the RGB LED setup. It’s easy and clear, and it gives you a lot of power. In fact, the RGB controls are among the most user-friendly you’ll come across.

Unfortunately, the program requires a Facebook or Google account to store profiles, but if you don’t want to connect a profile because you’re worried about how NZXT manages your data, you may run it in guest mode. You won’t be able to store your preferences.

The NZXT Kraken M22, like many other 120mm AIO coolers, is extremely compatible with most sockets. In terms of contemporary computers, only the AMD TR4 is left out. Intel’s 2066, 2011-3, 2011, 1366, 1200, 1156, 1155, 1151, and 1150 processors, as well as AMD’s AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, and FM1 processors, are all supported.

The Kraken M22 is a bit harder to install than other AIO coolers, but it’s still quite straightforward. The placement of the pump above the radiator distinguishes this cooler from other all-in-one coolers. As a result, air flow is restricted in comparison to conventional designs, which may have a detrimental effect on cooling performance. Aside from that, installation is as simple as securing a few screws, so just about anybody can set up this cooler without difficulty.

The NZXT Kraken M22 is a high-quality product. Its hoses are wrapped in nylon and resistant to bending and kinking, much like a few other coolers on our list, so you won’t have to worry about leaking. The Kraken M22 has a rubberized fan casing that helps keep it quiet while it’s spinning at its highest RPM, which is a nod to acoustic performance.

The Kraken’s performance is a little disappointing, particularly considering its price tag. This is one of the more costly 120mm coolers on the market, however there are many cheaper alternatives that offer far greater cooling for a lesser price. In comparison to other coolers, it’s also very noisy.

All things considered, this AIO cooler is well-designed, although it has a few flaws. Even in the 120mm class, greater cooling functionality may be found for less money. NZXT also provides a 6-year guarantee, which is the longest of any manufacturer on this list. You have to like the infinite RGB appearance for this cooler to be a decent bargain. If that’s the case, this cooler is well-made and comes with a guarantee, making it a worthwhile purchase.

One of the simplest cooler designs on the list is the EVGA CLC 120mm. It isn’t as showy as some of the more RGB-enhanced coolers, doesn’t have extremely amazing performance numbers, and doesn’t have any cutting-edge or out-of-the-box technologies. It’s simply a basic, no-frills product that may leave the more discriminating consumer disappointed.

The EVGA CLC 120mm’s basic model lacks RGB LEDs, which may be a disappointment for some, particularly considering its price. It might have done with a little bit to brighten up its very drab look.

Everything about this cooler is flat black, from the pump to the radiator to the tubing. It isn’t a very fashionable AIO, especially when compared to some of the others on our list. It might have benefited from the assistance on that front to improve its value offer.

All popular Intel sockets, such as the 1200, 115X, 2011-3, and 2066, as well as AMD AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, and FM1 sockets, are compatible with the EVGA CLC 120.

The quality of this EVGA cooler, on the other hand, is excellent. It has a fan housing that is curved to minimize noise. The bearings of the fan are likewise composed of Teflon, making them very durable and long-lasting.

It also has an attractive wiring scheme that will assist keep your project clean. The cable management solution would be appreciated by those who require a compact form factor cooler to fit in their tower.

The EVGA CLC 120 AIO performs similarly to other 120mm coolers in terms of performance. It isn’t the most durable 120mm cooler on the market, but it will suffice. It’s not the best cooler for a more powerful computer, but it’s been shown to lower CPU temperatures by an average of 8 degrees Celsius at idle and under higher loads.

When the fan is cranked up to 1800 RPM, it is very loud and obvious. Reducing the RPMs lowers the noise production, but it also substantially limits the cooling capacity.

Overall, the EVGA CLC 120 is a solid cooler that is an excellent fit for anybody who wants to avoid RGB lights for whatever reason. Its performance is adequate, and it compares well to other AIO coolers in its class, but you’ll almost certainly be able to find a better price on a cooler that performs similarly.

The EVGA is very plain in appearance and does not stand out in any manner. If that’s your style, you’ll enjoy the design’s simplicity. EVGA also includes a 5-year warranty, which adds to the cooler’s overall value. Overall, you may be better off with a less expensive or higher-performing AIO, but the EVGA CLC 120 will not let you down.
