Cooling Best Picks

We tested 90 different thermal pastes to help you find the best one to help cool your CPU.

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

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.
