The computer’s fans run automatically, but their speed is controlled by the sensors placed on the motherboard. All the fans work together to cool down your PC. There are usually three fans in a desktop computer, a main chassis/case fan, a CPU fan, and a power supply fan. That’s where the PC fans come into play, they are meant to expel heat out of the system to prevent the CPU from overheating and causing potential hardware damage. They use more power, generate more heat, and loud noises. Many Games (like Division 2) and editing software (like Adobe Premiere) put more stress on the CPU and GPU. If you are constantly hearing the loud, noisy sound of CPU fans, it’s because the computer is generating a great amount of heat. Should You Change Fan Speed If CPU Fans Are Loud? Here are our recommendations for the best fan control software for Windows 10 and 11, which will help you easily and efficiently set the custom fan curve.
