Best Overall: Corsair Hydro H100i

Stock coolers just don't cut it when it comes to style, performance, and scope for overclocking the CPU. Should you own an unlocked CPU and wish to take things a little further, the H100i can handle the increased heat output, especially if the airflow inside your case isn't optimal. Water cooling also makes it easier to get inside the case and mess around with components and for cable management, leaving ample space for people to gaze into the side panel.

As an added bonus, there can be LEDs installed on the pump unit, which is a handy addition for those looking to add some colored lighting to their PC. But the main reason to go with water over air is performance. While some air coolers (namely the CoolerMaster 212 EVO) are excellent at keeping temperatures down and dissipating heat, when you're overclocking the system in general, it's best practice to deploy some water cooling.

All-in-one coolers like the Corsair H100i are great solutions for those who wish to enjoy the advantages of water cooling but don't wish to construct their own loop. All that's required is for the pump to be installed on the CPU and the radiator attached to a compatible fan mount point inside the case. Plug in the necessary cabling and the job is done.

The only downside which we've found with Corsair's all-in-one sealed looped systems is the noise of included fans. The H100i, unfortunately, is no exception and can blow out some serious noise (and air). That said, you can look to replace the bundled fans with alternative ones you prefer. All in all, it's a great cooler, especially for overclocking.


  • 240mm radiator
  • Reliable and quiet pump
  • Companion software
  • Universal fitting


  • Fans can get loud

When you don't want to risk custom loops

Corsair all-in-one looped water coolers are great options for those moving from air cooling to liquid. The H110i unlocks great performance and allows for some degree of overclocking, though you'll certainly need to ensure your case and other cooling components are up to the task. The massive 280mm radiator is more than enough to cool down the CPU and allow for some room of overclocking (depending on other components, of course).

Best Value: Cooler Master 212 EVO

Cooler Master 212 EVO

Air cooling is the traditional method of cooling down your internal PC components, but that doesn't mean it's an outdated practice. Sure, water cooling brings many benefits, including enhanced thermal capacity, but you're paying out more and other minor drawbacks may arise like loud fan noise and the risk of leaks.

Cooler Master's 212 EVO is an incredible piece of kit. For the seriously low price, you get a CPU cooler that can even handle some form of overclocking on more powerful processors. This cooler allows you to enjoy all your favorite PC games, work through video editing, and much more without spending more on water cooling.

The cooler only comes with a single fan, but that means you can install a second fan for additional performance.


  • Great value
  • Amazing performance
  • Easy to install
  • Options for AMD
  • Can install a second fan


  • Not as good as liquid

Cooler Master 212 EVO

Among the best air-cooled solutions available

If you're not a fan (pun totally intended) of liquid cooling, then fans and heat sinks are your next choice. The 212 EVO by Cooler Master is among the best, especially at its asking price. Seriously, don't allow the low price tag put you off in believing this to be a cheap solution.

Best low profile: Cooler Master GeminII M4

A drawback of smaller cases is the lack of headroom for a large CPU cooler with a huge array of fans. This is where all-in-one water cooling kits come into play or low-profile air coolers like the Cooler Master GemenII M4. This compact cooler packs a punch for keeping your server or mini-PC cooled, so long as you don't plan on overclocking.

The direct contact heat pipes are able to take heat directly away from the CPU and transfer it straight to the fan for extraction, making the most of a compact environment where case airflow is more often limited. An additional advantage of Cooler Master CPU coolers are the incredibly quiet fans. You'd think this one would sound like a jet under load, but it doesn't.

Still, there are downsides to compact coolers such as this one, which is namely the thermal headroom. You won't be able to keep an AMD Threadripper or Intel Core i9 processor cooled, nor will you be able to do any form of overclocking, but you shouldn't expect to do so in a small factor PC case.


  • Ideal for compact cases
  • Perfectly suited for low to mid-range CPUs
  • Quiet fans
  • Direct contact heat pipes


  • Less thermal headroom
  • Not for overclocking

Best Low Profile

Cooler Master GeminII M4

Great for compact PC builds

Ideal for mini PCs and small factor setups, coolers like the GeminII M4 by Cooler Master enable builders to dissipate heat away from the CPU without taking up too much space. The fan on the GeminII M4 has the fan blow directly down towards the motherboard and CPU socket, which also lends a hand with chipset cooling by directing air towards motherboard heatsinks.

Best air cooler: Noctua NH-D15

Noctua is best known for producing some high-quality cooling solutions for PC builds. The Noctua NH-D15 is an incredible air cooler and the asking price reflects that. The six heat pipe dual tower design maximizes the amount of headroom available for cooling. Simply put; you'll be able to overclock powerful CPUs with this cooler.

And not only is the overall unit massive in size, but there are also two fans pre-installed for maximum heat dissipation and airflow efficiency. You can think of the NH-D15 being two CPU coolers combined into a single package and you wouldn't be far off the mark.

Best of all, since you're rocking two fans, you won't notice much noise unless they're at maximum speed and you won't require them to be often at all. Overall, it's one of the best air coolers around.


  • Impressive performance
  • Great for overclocking
  • Quiet operation


  • Bulky cooler

Noctua NH-D15

One of the best CPU air coolers you can buy

Noctua is highly rated by many system builders for releasing some of the best fans available. Pair up the company's superb blades with a large heat sink and you have the NH-D15, which will help keep your CPU cool.

Cooler Master not only created an AIO that looks sleek and ready for an exquisite build but also included some serious headroom. If you're wanting to do an interesting PC build with RGB lighting and overclocked internals, you'll want to consider the excellent MasterLiquid ML360R from Cooler Master.

The dual-chamber pump is quiet and efficient, pumping enough coolant around the loop to keep the CPU cool. Because of the 360mm radiator, you can even use this cooler to increase the airflow within the PC case too, which is just as important.


  • Impressive performance
  • Great for overclocking
  • Three 120mm fans
  • RGB lighting


  • Requires 360mm mount

Silent performer: be quiet! Dark Rock Pro 4

This is one for the serious PC builder, with a whopping 250W TDP support, dual-tower design, seven heat pipes, and two 120-mm fans. With all that cooling power it's still whisper-quiet. How? We don't know, but your PC will love it. And so will your ears, though you'll pay for the privilege.

While it may seem like a lot of money to shell out for a cooler, especially an air one, but it's well worth it. Looking at the cooler from the side, you can even spot how the fans are shaped differently, comparing the front spinner against the one located in the middle. The best part is this cooler will work with the latest Intel and AMD processors.


  • Impressive performance
  • Great for overclocking
  • Sleek looks
  • Quiet operation


  • Bulky cooler

Silent Performer

Amazing performance with low noise

be quiet! built its brand around offering performance parts for PC enthusiasts that crave a more silent experience. This sleek, all-black hunk of metal and fan delivers on that front.

Bottom line

The best value solution is the Cooler Master 212 EVO, which offers incredible value for money when you consider available performance and the ability to handle some degree of overclocking. When you're not stressing the system, you'll barely hear the fan turning.

But if you want to really take your cooling to the next level, you'll need to try out the Corsair Hydro 100i all-in-one water cooler. This is for more demanding PCs and allows you to get more from your CPU, but just beware for noise when the fans run at high speed,
