It depends on your laptop’s make and model. The majority of laptops use Function keys (F1-F12) to have access to BIOS on the startup screen.Īfter reaching the BIOS, you can find the fan speed’s controlling option in the advance setup or configuration submenu. You can easily access the BIOS settings by pressing the specific key (mentioned on the boot screen) at the startup. In some laptops, the user can set the speed of the cooling fan through BIOS. The BIOS in your laptop is basically a program that plays an important role in controlling the hardware. That’s why today we have brought you a tutorial in which we will explain three different methods to set the cooling fan’s speed. At the same time, low CPU temperatures may be the first priority for some users even if the fan is making noise (while running at high speed).

There is no doubt that the lower temperature of the CPU would increase its lifespan.įor some users, the constantly heating up of the CPU might not be important, they might prefer a noiseless fan over this. While normal usage, its speed would be slow and almost quiet. By default, it is mostly set at auto speed, if the user puts much pressure on the CPU, the speed of the cooling fan will increase and you might be able to hear the fan noise. It cooldowns the processor and other related equipment when the users put excessive pressure (while using heavy programs) on it. A cooling fan in a laptop plays a very important role.
