You can also see that there are many CPU coolers in the market, but with different features and price, so which one should you choose?
CPU cooling has seen dramatic improvements in the last few years. Motherboard makers such as MSI, Gigabyte and ASUS have all released their own versions of AIO cooler with improved features like RGB LED effects and RGB controlled fans. Recently, there has been a new entry in the AIO cooler market with its own unique look, features and pricing. Unlike other coolers, which are sold in 120mm form factor, Noctua’s NH-D15 SE-AM4 AIO cooler is sold in a 170mm form factor.

After reviewing the top 120mm AIO CPU coolers available for purchase, we’ve finally come up with a solid list of the best 120mm AIO liquid coolers going forward.

2. ROG Strix LC 120 from ASUS
When it comes to constructing a gaming setup, the ROG line of devices is usually one of my first picks. While searching for 120mm AIOs, I came across one from this series that might be ideal for your mini-ITX setup.
The following are the specifications for this ASUS model:
- RPM of the fan: 800-2500
- 37.6 decibels decibels decibels decibels decibels decibels decibels deci

This ASUS water cooler is one of the most elegant and sturdy-looking cooling options available. It is undoubtedly one of the best choices due to its contemporary appearance and great cooling capacity.
At first look, you’ll notice its pump head, which is imprinted with the ROG emblem. This logo is absolutely delightful when the RGB LEDs in the pump are turned on.
Added to that:
The whole texture of the cooler is so beautifully done that when the RGB LEDs reflect inside the rig, it produces a brilliant burst of colors.
A single fan with an improved design is also included with this cooler. It performs well at reasonable speeds. The greatest aspect is that it doesn’t have to operate at full speed to keep the system cool. Check out some of the best CPU coolers for the AM4 socket.
Installing this AIO cooler in your system will take you no more than 10 minutes at most. Furthermore, it is extremely compatible with contemporary CPUs due to the broad variety of socket compatibility provided by both Intel and AMD platforms.
However, if you intend to use the fan at maximum speeds, it is possible that it may become too noisy. As a result, I recommend that you keep your speeds modest.
Overall, I’m certain that you’ll like this cooler because of its high-end performance and colorful lighting profiles. Although it is a little expensive, this is one of the finest 120mm AIO coolers available for your high-end system.
NZXT Kraken M22 is the third product in the NZXT Kraken M22 series.
If I don’t include a NZXT cooler in my list of best AIOs for a gaming setup, it will be incomplete. Almost all gamers have confidence in their Kraken coolers.
This model from NZXT’s Kraken series has some impressive features:
- 500-2000 RPM fan speed
- RPM of the pump: 2700-3000
- Warranty period: 6 years
Check out the current price of the NZXT Kraken M22.
This cooler is an excellent representation of the series to which it belongs. It has a striking look that I believe will entice most players to purchase it.
The infinite mirror appearance on the pump head is one of the design’s most prominent features. The vividness of the lights will wow you as the RGB LEDs light up the pump. This is why I consider this AIO to be the Cooler with the Best-Appearing Pump. Also, have a look at some of the finest 240mm CPU coolers.
It gets better since, due to NZXT’s CAM software, the lighting flairs in the pump head are extremely programmable.
This cooler also has a single fan with a noise level that ranges from 21 to 38 dBA. Even at maximum RPM, the rubberized casing makes it less noisy. The fan’s main flaw is that it isn’t RGB, which I believe should have been included.
Aside from the non-RGB fan, this cooler is fantastic in my view. And, with a 6-year guarantee, I believe it is a solid choice for pairing with a high-end CPU. This month, check out the award-winning best nzxt aio cooler.
4. Hydro Series H60 by Corsair
For PC peripherals, I always choose Corsair as a brand. And they are a huge fish in the market for cooling solutions that everyone admires.
However, this liquid cooler from them has several outstanding features:
- 600-1700 RPM Fan Speed
- Noise level: 28.3 decibels (dBA)
- Warranty period: 5 years
Check the current price of the Corsair Hydro Series H60.
When it comes to design, this cooler from Corsair isn’t over the top. The black and white texture pretty much sums up how simple this cooler is.
Its pump head is stylish and has a touch of refinement to it. The radiator also seems to be in good condition.
The fan and pump on this liquid cooler are the greatest features. They’re nearly deafeningly quiet. Don’t forget to look at the finest noctua cpu cooler on the market as well.
There is no noise at all, even when the fan is operating at full power.
Now, there’s also the issue of cooling potential to consider. In my tests, this water cooler was able to withstand high temperatures with ease.
But there were a few things that I didn’t like for. The fan, for example, lacks RGB components, and the pump’s light cannot be turned off.
Apart from that, I was also dissatisfied with the cooler’s setup procedure. This must be done via BIOS, which may seem to be a difficult process.
To summarize, this isn’t your typical showy RGB cooling system. It has a simple design and provides excellent performance.
It’s the finest 120mm water cooler to consider as a mid-range choice. Check out the TR4 socket compatible CPU cooler.

The following are the specs for this EVGA model:
- 1800 RPM maximum fan speed
- 20-32 decibels of noise
- Warranty period: 5 years
Check EVGA CLC’s current price.
EVGA’s cooling systems are often the most cost-effective. One of them is this cooler. It performs well as a cooling solution for a low-cost construction.
You don’t have to be concerned about compatibility. It works with nearly all Intel and AMD sockets. However, it isn’t a high-end option in terms of performance. As a result, I recommend not raising the bar too high for this cooler.
Like most other cheap coolers, the design is very simplistic. Additionally, there are no RGB components in the cooler, fans, or pump.
When it comes to the fan, it is of excellent quality. Especially the high-quality bearings that keep it going for a long time.
The fan, on the other hand, is not without flaws. At maximum speeds, it becomes very noisy, and lowering the speeds has a little impact on cooling performance.
Expect nothing from this chiller in general. It is the simplest choice available for your gaming setup.
The 120mm AIOs may not provide extreme performance as cooling solutions, but they may keep your mini-ITX system surprisingly stable.
