The best all-in-one (AIO) cooler does everything. It keeps your CPU at a good temperature and saves you the trouble of setting up your own liquid cooling system. The cooling system for a computer takes care of everything at once. It has a direct effect on how well your computer works and keeps it cool and quiet. Traditional CPU coolers with a heatsink and a fan are great for keeping your desktop processors running at the right temperature.
Still, if you want to overclock the CPU and put it under a lot of stress, you’ll need to buy a more complicated water cooling system. There are some great plug-and-play all-in-one (AIO) kits on the market from well-known brands. We’ve put the following coolers through a lot of tests, and one of them is one of our top picks. We’ve included solutions with a wide range of prices and different kinds of features.

DeepCool Liquid Cooler LT720
| Specification | |
|---|---|
| Radiator Dimensions | 274mm x 120mm x 27mm |
| Fan Dimensions | 120mm x 120mm x 25mm |
| Fan Speed | 500 – 1800 RPM |
| Noise Level | 16 – 31.3 dBA |
| Pump Dimensions | 80mm x 80mm x 60mm |
| Pump Speed | 2550 RPM |

If you want to get the most out of your new Core i9-13900K CPU over time, DeepCool’s LT720 AIO is the best CPU cooler we’ve tested so far with Intel’s latest flagship CPU. During our Cinebench tests, the 360mm AIO kept our CPU running at a very good 315 Watts. It also has a unique cover for CPU that looks like an infinity mirror and stays out of the way of your RAM.
When this cooler is running at full speed, it can get a little noisy. But if you bought a Core i9 and are running it at full speed with the power limits removed, a bit of extra fan noise is probably not your biggest concern. This is the best Raptor Lake option we’ve tested if you need a lot of cooling for your overclocked flagship CPU and don’t want to spend several hundred dollars on custom cooling.
The Good
- Effective performance in cooling
- It works with a wide variety of CPU sockets.
- Compact radiator size
The Bad
- Fans can get quite loud at maximum speed
- Installation can be hard for people who aren’t used to building PCs.
Arctic Liquid Freezer II 360 ARGB
| Specification | |
|---|---|
| Radiator Dimensions | 397mm x 120mm x 38mm |
| Fan Dimensions | 120mm x 120mm x 25mm |
| Fan Speed | 200 – 1800 RPM |
| Noise Level | 0.08 – 0.3 sone |
| Pump Dimensions | 98mm x 78mm x 53mm |
| Pump Speed | 800 – 2000 RPM |
| Compatibility | Intel LGA 1200/115X/2011(-3)/2066, AMD AM4 |
If you care more about quiet operation than cooling power, Arctic’s Liquid Freezer II 360 ARGB is a great choice. It cooled our Core i9-13900K almost as well as the DeepCool LT720, but was quieter during our tests. Long-term testing with the 13900K showed that Arctic’s 360 mm cooler could handle more than 290W.
This makes it a good choice for people who run demanding workloads. Just make sure there’s extra space in your case where you want to put it because it has a thicker radiator than most of its competitors, which is what makes it quiet. So it won’t fit as well in smaller cases or ones that don’t have much space on top.
The Good
- Excellent ability to cool
- Low noise levels
- Easy to set up
The Bad
- A radiator that is relatively big might not fit in a smaller case.
- Not everyone may like RGB lighting.

EK is a well-known brand name in the world of liquid cooling. The EK Basic series is all about performance and getting the most for your money. Also, it doesn’t have any RGB, which helps keep the price down. If this sounds good to you, you should check out the EK AIO Basic 240. The EK Basic 240 stands out because of how well it is made.
It’s big and well made. The EK-Vardar fans that come with the case are very good and can run at a wide range of speeds. If you have high-speed headroom, you can use it when you need to. Most of the time, it doesn’t make much noise. What really impresses us is how well it keeps things cool. We think it cools about as well as a 360mm cooler.
The Good
- Great cooling performance
- Easy to set up
- Most PC builds work well with designs that are simple.
The Bad
- Fans can get loud at maximum speed
- Relatively expensive compared to other options on the market
Deepcool Gammaxx L240 V2
| Specification | |
|---|---|
| Radiator Dimensions | 274mm x 120mm x 27mm |
| Fan Dimensions | 120mm x 120mm x 25mm |
| Fan Speed | 500 – 1800 RPM |
| Noise Level | 17.8 – 27 dBA |
| Pump Dimensions | 80mm x 80mm x 60mm |
| Pump Speed | 2550 RPM |
| Compatibility | Intel LGA 2066/2011(-3)/1366/115X, AMD AM4/AM3+/AM3/AM2+/AM2/FM2+/FM2/FM1 |
Deepcool is known for making good AIOs at low prices, and the Gammaxx L240 V2 is one of the least expensive 240mm coolers you can buy. This makes it a good choice for people who want to move up from air cooling to AIO cooling. The pump head and fans on the Gammaxx 240mm have simple RGB lighting.
If you really want it, there is an ARGB version that costs more. Deepcool likes to talk about its “Anti-leak technology,” which tries to keep the pressure inside the loop in the best way possible. Which can’t do any harm. The Gammaxx 240 can also cool most processors, but it can’t handle AMD’s Threadripper beasts, like many of the other chip chillers on this list.
The Good
- Cooling that works well
- Affordable price point
- Easy to set up
The Bad
- When fans are going fast, they can make a bit of noise.
- The only place with RGB lighting is the pump head.
MSI MEG CoreLiquid S360
| Specification | |
|---|---|
| Radiator Dimensions | 394mm x 120mm x 27mm |
| Fan Dimensions | 120mm x 120mm x 25mm |
| Fan Speed | 500 – 2000 RPM |
| Noise Level | 14.3 – 34.3 dBA |
| Pump Dimensions | 80mm x 80mm x 53.3mm |
| Pump Speed | 4800 RPM |
| Compatibility | Intel LGA 1200/115X/1366/2011/2066, AMD AM4/AM3+/AM3/AM2+/AM2/FM2+/FM2/FM1 |
The MEG CoreLiquid S360 is not MSI’s first AIO cooler, but it is the best for three reasons: cooling, compatibility, and the extra care it takes. Not only does it have great performance and low noise, even when the Silent Gale P12 fans are spinning at 2,000RPM, but it also comes with an LGA1700 bracket that works with Intel’s latest Alder Lake CPUs.
It even has a 60mm fan in the pump to keep the VRMs on the motherboard cool, which is something that most other AIOs don’t do. MSI’s best feature is the built-in screen. This isn’t a new idea, but MSI’s MEG CoreLiquid S360 does it the best. This 2.4-inch IPS display, like most others, can show pictures, GIFs, and information about the system.
The Good
- Cooling performance that is impressive
- RGB lighting gives your build a stylish touch.
- Simple to set up and use
The Bad
- At full speed, fans can be a bit noisy.
- Compared to other AIO coolers on the market, this one is pretty pricey.
NZXT Kraken X63
| Specification | |
|---|---|
| Radiator Dimensions | 315mm x 143mm x 30mm |
| Fan Dimensions | 140mm x 140mm x 26mm |
| Fan Speed | 500 – 2000 RPM |
| Noise Level | 22 – 36 dBA |
| Pump Dimensions | 80mm x 80mm x 55mm |

| Compatibility | Intel LGA 1151/1150/1155/1156/1366/2011/2011-3/2066, AMD AM4/AM3+/AM3/AM2+/AM2/FM2+/FM2/FM1 |
If you want a really good all-arounder, we recommend this 280mm liquid cooler from NZXT. The fans on the radiator are almost silent because they use fluid-dynamic bearings. This makes them last longer and run more quietly than any other fan technology.
The pump cover has customizable RGB lighting so that people know you aren’t using a stock solution. With the X63, idle and load temperatures will be much higher than with air coolers. Make sure you get one of the best gaming motherboards if you’re going to overclock.
The Good
- Good job of keeping things cool
- A big radiator helps get rid of heat quickly.
- There are many ways to change CAM software.
The Bad
- Compared to other AIO coolers, the price is pretty high

| Compatibility | Intel LGA 1200/115X/1366/2011/2066, AMD AM4/AM3+/AM3/AM2+/AM2/FM2+/FM2/FM1 |
This 240mm cooler works with the latest AMD and Intel processors, including AMD’s Threadripper processors. With a copper cold plate, it pulls heat away from your CPU and pumps it into a 240mm radiator with two 120mm Corsair ML Series fans. It works quietly and well when your CPU is cool, and it makes the most noise when it is running at full speed (75CFM). It’s also easy to take care of the AIO cooler.
With Corsair’s iCUE software, you can control the speed of your fans and pumps right on your PC. You can also check the temperature of your CPU to make sure your settings are giving you the best performance. The head of the pump has 16 RGB LEDs, and you can control each light with the iCUE software. This is great if you also like to look good. Corsair is a well-known and respected brand, and there’s a reason for that.
The Good
- Great cooling performance
- iCUE software gives you a lot of ways to customize it.
- The RGB lighting works well and looks great.
The Bad
- At full speed, fans can be a bit noisy.

- NZXT Kraken X63
- NZXT Kraken M22
- Corsair H100i Pro RGB
- Cooler Master MasterLiquid ML360R
Are AIO coolers any good?
An all-in-one (AIO) liquid cooler not only cools more quietly than a traditional air cooler, but it might also lower temperatures enough to let you overclock more. AIOs are a very easy way to cool your PC with water without making a mess or having to choose parts.
What is the best size for a AIO cooler?
If you’re building a mid-tower PC on a budget, a 240mm AIO cooler would be a good choice, but if you can afford the best, don’t settle for anything less than a 360mm liquid cooler, as long as your case can fit it. Save the 120mm AIOs for ITX builds.
What is the #1 cooler?
The RTIC 65 QT Hard Cooler was the best for the price and how well it worked out of all the models we tested, which included the very popular Yeti Tundra 65.
