Choosing the best CPU cooler for your next build isn't easy. Between liquid and air options, a variety of different form factors, and differences in performance, it's important to choose a cooler that will keep your processor at a reasonable temperature.
There is no one-size-fits-all option. To help narrow down your search, we've compiled a list of CPU coolers that will keep every processor nice and cool, including some of the top CPUs.
Noctua NH-D15
The best CPU air cooler
- Excellent cooling
- Vast compatibility
- Relatively quiet even at full RPM
- It's really bulky
- Not the cheapest cooler
Why should you buy this: If you have a midrange or even high-end CPU, but don't want a liquid cooler.
Who's it for: Gamers and other users in need of efficient cooling.
What we thought of the Noctua NH-D15: Noctua produces some of the best CPU coolers available. The NH-D15, with its dual heat sink and fans, offers performance that rivals or exceeds some of the best all-in-one (AIO) coolers in the world while retaining that off-the-beaten-track color scheme that has defined Noctua since its debut. (If you're not into brown and beige, it's also available in black at a small premium.)
This cooler has been around for many years now, but it's still able to compete against newer cooling solutions, and that's even on recent processors. This is a 160mm fan with a TDP of 220 watts and a RPM that maxes out at 1,500. It's efficient, capable, and fairly quiet for a fan of this size and performance.
The NH-D15 is both bulky and heavy, so it isn't perfect for every system. It's also quite expensive. However, if you want the ultimate in air cooling on just about any socket of recent generations, you can't go wrong with the NH-D15. Keep in mind that if you're an overclocker, switching to a liquid cooler might be a safer option.
Cooler Master MasterLiquid ML240L RGB V2
The best 240mm liquid cooler
- Affordable for a liquid cooler
- Reasonably easy to install
- Efficient cooling
- Not powerful enough to handle massive overclocking
- It can be a bit loud
Why should you buy this: It's an efficient AIO cooler that's nowhere near as bulky as bigger options.
Who's it for: Gamers who like a bit of RGB and have a CPU that needs more than just an air cooler.
What we thought of the Cooler Master MasterLiquid ML240L RGB V2: When you first step into liquid cooling, the whole process might seem a little intimidating. If you're working with a massive cooler, there are also many more considerations, such as the fit and the installation process. That's why, for many users, the MasterLiquid ML240L v2 is a great entry into the world of AIO cooling that's a lot more hassle-free than 360mm or 420mm options.
This is an improved version of a previous Cooler Master model that was also a bit of a fan favorite, and this one follows in its footsteps. It offers a larger radiator surface area for better heat dissipation, an upgraded pump for enhanced performance, and improved SickleFlow RGB fans. The fan speed is rated at 650 RPM to 1,800 RPM, and it has a massive life expectancy.
Cooler Master's AIO cooler is a fairly inexpensive, and yet efficient, liquid cooler that will fit in most mid-tower and full-tower setups. It's an upgrade over many air coolers, so if you've got one of the best processors, it's worth considering.
Thermalright Peerless Assassin 120 SE
The best value CPU air cooler
- Extremely good value
- Low noise levels
- It can tackle even high-end CPUs
- Not recommended for overclocking at higher TDPs
Why should you buy this: It's an inexpensive CPU cooler suitable for all kinds of builds, from entry-level to high-end.

What we thought of the Thermalright Peerless Assassin 120 SE: When you want a cooler that suits both the latest CPUs and those from a couple of generations back, there are lots of options to choose from. However, if you want one that's actually great, compatible with most processors, and cheap, it gets trickier. Fortunately, this Thermalright cooler ticks all three of those boxes.
The Thermalright Peerless Assassin 120 SE comes with a dual-tower heat sink and two 120mm fans that hit a maximum of 1,550 RPM. As far as coolers go, it's fairly easy to install, and it's not as bulky as the Noctua NH-D15, although you'll still struggle to fit it inside a mini-ITX case.
Although its price falls in the $35 to $45 range, this is an efficient cooler that can handle even high-end AMD and Intel processors. At higher TDP values, you might want to avoid overclocking, but for day-to-day use, this one is hard to beat.
Noctua NH-L12S
The best small form-factor CPU cooler
- Fits in small cases
- Suitable for SFF and HTPC builds
- RAM clearance can get tricky
- Not suited for high-end CPUs
Why should you buy this: Anyone building a small form factor PC that needs some cooling.
Who's it for: Gamers and regular users with a PC inside a tiny case.
What we thought of the Noctua NH-L12S: If your PC is lightweight or low-profile, then you need a low-profile CPU cooler to take the most advantage of it. That's where Noctua's NH-L12S really shines. At just 70mm tall, it will fit into the most diminutive of mini-ITX chassis, making it a great option for those looking to cool a powerful CPU in a small system build.
It supports a wide array of Intel and AMD sockets from the past few generations and uses a simple clip mechanism to lock its fan in place. Attractive, lightweight, and capable, this is the best CPU cooler for low-profile builds and mini PCs. However, make extra sure that there's enough headroom for the RAM, as some users run into issues with RAM clearance.
The only caveat with this cooler is that it doesn't have the same thermal headroom as some others on this list. Noctua advises using the NH-L12S with "care" with CPUs over 95W TDP or when overclocking, as it may not be able to keep the temperatures low enough to remain safe.

However, if you have a roomy case and a PC that needs to stay cool, this is the go-to for enthusiasts.
Frequently Asked Questions
AIO liquid coolers typically provide better cooling than their air counterparts, but that doesn't make them inherently better. They are better for the PC builds that require it, meaning high-end and midrange computers with CPUs that tend to heat up. Many users with PCs in the lower midrange to entry-level bracket have zero use for AIO coolers, and for them, a reliable CPU fan is all that's necessary.
Gaming CPUs, especially those that are overclocked, tend to heat up a lot. If you're using one of AMD's top processors, meaning the Ryzen 7 7800X3D or the 7950X3D, a liquid cooler like the Arctic Liquid Freezer II 360 is a great way to ensure that your PC won't overheat. However, if you're sticking to processors like the Ryzen 7 5800X3D or the Intel Core i5-13600K, air coolers are often a better option, such as the Thermalright Peerless Assassin 120 SE mentioned above.
