Cooling Best Picks

These are the best air and liquid/AIO CPU coolers we've tested, for all consumer systems, from small form-factor builds to overclocked big rigs.

After measuring CPU temperatures and fan noise for dozens of AIO coolers under load, we've chosen the best closed-loop cooler options to keep your PC cool and quiet.

We tested 37 different thermal compounds with AMD’s Ryzen 9 9950X and over 90 thermal compounds with Intel Core i9 CPUs to help you find the best one to help cool your CPU.
