But when CPU and GPU temperature get too high, both hardware will reduce their performance to gradually dissipate heat. By reducing heat, your CPU and GPU will continue to operate at their optimal levels. And so, to dissipate this heat, fans will keep the system cool by turning up the RPM (revolutions per minute). When CPUs and GPUs are operating, they will generate large amounts of heat, which is not good for these sensitive components. But if someone is doing heavy-duty gaming, the GPU fans will work their butts off. In this case, whenever someone is rendering a video, CPU fans will work harder than the GPU fans.

Granted, you’re not hearing the sound of a sedan in your room whenever you boot the PC, but the whirring noises may be too much for certain people.ĬPU and GPU fans emit noises because both hardware are expending lots of energy to carry out their corresponding processing tasks.

Gamers will know what it’s like to deal with the constant noises of a PC fan, even when they’re at minimum fan speed setting. Some of the software listed will also allow you to monitor your system, overclock CPU and GPU, on top of letting you adjust fan speeds. This article will cover the best fan control software that controls fans speeds without any difficulty. Luckily, there’s a fix for this and you don’t need to replace your fans just yet.
