Overheating PC is a general problem when any software is used if the fans are not working properly. Dedicated software programs can be installed and used to control the CPU fan speed.ĬPU fan is one of the most important parts of one’s computer or laptop as the fan helps the system stay cool and quiet. Yes, you can change the fan speed of a laptop CPU without using BIOS. How to Change CPU Fan Speed Without BIOS?Ĭan I change the CPU fan speed without BIOS?.Can I change the CPU fan speed without BIOS?.Even if your system has more than three fans, it is important to maintain individual control over all of them. Usually, there are at least three fans in a PC: The intake or exhaust fan, either at the back or front of the case, the heatsink fan, and the power supply fan which is almost always at the back of the PC where it expels hot air. If heat levels are higher than they should be, these sensors quickly pass the information to the fans so they can adjust their RPMs to compensate and avoid any long-term damage to the hardware. It does this by detecting the components’ temperature level using embedded sensors on the board. The motherboard controls the flow of temperature information to the fans, thus regulating their RPM.

The function of these fans is sometimes not readily available to the user without the appropriate software.įans are vital components of any PC build, but they don’t run on their own. This airflow helps to keep the PC performing at optimal levels but, in some cases, it can cause the fans to accelerate to an extreme level. Excessive heat is not good for delicate hardware components, and so the fans increase their RPM to help expel hot air from the casing and replace it with cooler air. When running processes like this, the CPU, GPU, and various other components begin to generate excessive amounts of heat. Some examples of strenuous jobs that a computer might have to manage are playing graphically-rich video games (EX: Cyberpunk 2077) or using video editing software (Adobe Premiere). heat) while heavy-duty processing is underway. Usually, PC fans are loud because the computer’s hardware is generating considerable energy (i.e. Anyone who has ever had to put up with the constant whirring of a computer fan while trying to concentrate on a task knows exactly how annoying and distracting this sound can be.
