PC fans are one of the most important components in your PC. It keeps the rest of the computer at safe temperatures so it can function. Overheating in your PC can cause poor performance in your hardware, so if your PC is getting too hot, it may be time to invest in a better PC fan.
Here are the best PC fans you can buy.
What You Should Look For in a PC Fan
Fans should be able to rotate at high speeds (rpm) to keep your computer safe from overheating. However, a fan with too high rotational speeds is prone to being noisy. Although less effective, fans that operate on a lower rotational speed are less audible. The noise factor will vary in importance from person to person.
