How to change case fan speed without BIOS

how to change case fan speed without bios

As computer hardware technology advances, it becomes essential to have sound cooling systems in place to prevent overheating and hardware failure. One of the main components of a cooling system is the case fan, which circulates air throughout the computer case to cool down the components inside. 

In some cases, it may be necessary to adjust the speed of the Case & CPU fan to improve the cooling performance. However, not all computer motherboards support fan speed control through the BIOS. 

So, how to change case fan speed without BIOS? In this article, we will explore some methods that can help you to change the case and CPU fan speed without BIOS.

There are 2 best ways to change case fan speed without bios:

Are you tired of the noise your computer Case and CPU fans make, but don’t want to go through the hassle of accessing your BIOS to change their speed? Fortunately, there are several ways to change your case fan speed without going into your BIOS. In this article, we will go over five methods that can help you adjust your fan speed without any BIOS access. 

Method No:1 Use Fan Control Software

The first way to control your fan speed without accessing the BIOS is by using fan control software. The software will allow you to manage your computer’s fan speed, control overheating, and manage noise levels. Here are some popular fan control software:

Method No:2 Use Hardware Fan Controller Device

Another way to change case fan speed without BIOS is by using a hardware fan speed controller. This device is placed in between your computer’s power supply and your fans, allowing you to manually adjust their speed. Fan speed controllers come in both manual and automatic fan controller versions, and they can be purchased at most computer stores and online like Amazon.

External fan controllers come in different types, including fan hubs, fan splitters, and fan controllers with a digital display. These devices allow you to connect multiple fans and adjust their speed individually or as a group.

Here are some of our device recommendations you can check:
