Best Fans for Radiators – The most important metric for picking out a radiator fan is always going to be the static pressure. That doesn’t necessarily mean that a higher number is better. Depending on the fins per inch of your radiator, you can often get away with less.
Higher amounts of static pressure will also usually mean more fan noise, which is often a part of why you made the switch to liquid cooling. If you’re doing major overclocking or otherwise have a large need for cooling, you may want to consider keeping your tower further from where you typically sit to reduce the noise.

WRAP UP
Best Fans for Radiators – Liquid cooling is the best way to get the highest performance out of your PC, no question about it. But even liquid cooling will require fans to keep your radiators cool. This can be tricky because the best radiator fans are going to be different from the fans you’d be using for an air-cooled rig.
To help with your build, we’ve put together a list of the 10 best radiator fans available in 2021, with options for both 120mm and 140mm fans. All of the fans on our list are PWM, which means their speed can be controlled by your motherboard and adjusted based on moment-to-moment heating demands
