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).

Bottom line: Should you be looking up liquid cooling but don't wish to risk custom loops, the H110i is a superb place to start.

One more thing: The fans included with the cooler can be rather loud, especially if you unlock increased CPU performance.

Why the Corsair H110i is the best

We found the H110i from Corsair to offer great levels of cooling performance for the price, allowing for a neater setup with less space inside the chassis dedicated to massive heat sinks and fans.

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 H110i 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, 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 H110i are great solutions for those who wish to enjoy the advantages of water cooling, but do not 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 H110i, 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.

Best Air Cooler

Noctua NH-D15

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

Bottom line: Need the best when it comes to air cooling your CPU? You'll definitely need the Noctua NH-D15 installed.

One more thing: The cooler comes with two NF-A15 fans in a push-pull configuration.

Best Budget

Cooler Master 212 EVO

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. There's even scope for a little overclocking, though you will need to ensure you have sufficient case cooling. Seriously, don't allow the low price tag put you off in believing this to be a cheap solution.

Bottom line: The Cooler Master 212 EVO is among the best air-cooled solutions available. Great value for the included performance.

One more thing: The fan mounting brackets are incredibly easy to use and make maintenance a breeze.

Best Low Profile

Cooler Master GeminII M4

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.

Bottom line: If you're limited in space or use small form factor cases then the GeminII M4 will work wonders.

One more thing: This cooler sports four direct contact heat pipes.

Best Design

MSI Core Frozr L

This nickel-plated copper-base-sporting CPU cooler is a premium solution from MSI. The 120mm fan is hooked up to a capable heatsink (with LED lighting and the usual MSI branding) with a mounting bracket that supports most sockets in both Intel and AMD camps.

Bottom line: A great-looking CPU cooler that would fit right in with an MSI-only PC build.

One more thing: Supports the latest AM4 socket for AMD Ryzen processors.
