How To Change CPU Fan Speed Without BIOS? – 2023 Ultimate PC Guide

If you are an avid user of a PC, then you must be aware of the annoyance of your PC not working properly and malfunctioning due to overheating. The malfunction due to overheating is a very common occurrence that is a result of the fan not doing its job accurately. Therefore, you need to change the speed of your CPU fan using BIOS.

Most gaming motherboards have advanced BIOS user interface, making changing the speed of the CPU fan easy task.

However, that method may not work all the time. A second solution to this problem that has proven effective is to change CPU fan speed without BIOS. In this article, I have shared all the information that you will need while learning how to change CPU fan speed without BIOS.

Changing CPU Fan Speed Without BIOS


Why Change CPU Fan Speed

The need to change the CPU fan speed may arise when your PC starts lagging due to overheating. Overheating happens when the fan is not working properly, which then affects the entire operation of the PC, and slows down the operating speed of the PC.

This mostly happens when you run heavy files or games on your PC. The simple way to eliminate this annoyance and improve the speed of your PC is by changing the speed of the CPU fan. When you increase the speed of the CPU fan, it dissipates the heat, which then improves the performance of the PC.

Changing CPU Fan Speed With BIOS

There are two ways of changing CPU fan speed; the first is by the usage of the Basic Input Output System, also known as the BIOS. To change the setting with BIOS, you need to press F2 when the PC starts to open the BIOS settings. From there, select the cooling setting by using the arrow up and down keys.

Alter the fan settings from there. Once the settings have been changed, press F10 to close the BIOS settings. It is an easier method; however, it is not always effective, and in some cases, you can not even access the fan control settings.

The second method of changing CPU fan speed is without using the BIOS settings, and this method has proven to be more effective. It is also easier to change the CPU fan speed without BIOS. There are two ways that you can use to increase the speed of your CPU fan effectively.

Use A Fan Control Software

The first method of increasing or changing the speed of a CPU fan is by using fan control software. There are many fan control software available in the market that tests the speed of your CPU fan and automatically adjusts it as much as needed.

Moreover, once you have fan control software on your PC, it does not offer a one-time job. Every time your CPU starts heating up, the software adjusts the speed of the fan to cool the system down. Some of the best fan control software are Corsair Link, NoteBook FanControl, Argus Monitor, SpeedFan, Mac Fan Control, and Gigabyte EasyTune.

Installing SpeedFan

As other software requires you to purchase them, I am going to tell you about the one that you can get for free. The SpeedFan software is one of the best fan control software in the market that monitors and controls the speed of the fan and the temperature of the CPU.

The feature that I love about this software is that it has two features, manual speed control, and automatic speed control. The manual speed control allows you to manually adjust the speed, while the automatic speed control automatically adjusts the speed according to the requirements.

To get your hands on this software, first, you will need to download and install the software. After installing it, run the software on your PC and configure the fan control settings. After opening the software on your computer, click ‘configure,’ then go to ‘advanced.’

Once you have done that, select the ‘chip menu.’ Once that is done, switch all the PWM options to manual and click ‘ok.’ This will allow you to control the fan speed manually. For automatic speed control, click on ‘Configure’ and ‘Fan Control.’ Once that is done, select the ‘advanced fan control’ and ‘temperature,’ your setting will be set to automatic speed control.

Use an External Fan Controller

If you do not want to install any fan control software, the second method of controlling the CPU fan speed is by using an external fan controller device. There are many external fan controller devices in the market. Some of the best are Corsair Commander Pro and Thermaltake Commander F6.

Thermaltake Commander F6

The Thermaltake Commander F6 is the best as it allows you to connect up to 6 fans to the device. The LCD screen of the device shows the temperature and the fan speed and the 6 control knobs allow you to control the fan speed manually. Moreover, this device also has 6 temperature sensors for each device, so if any fan heats up, you get notified.


Can CPU fan speed be controlled?

Yes, you can control the speed of your CPU fan. There are two ways of controlling the speed, either via BIOS settings or without using BIOS settings. If you do not use BIOS settings, then you can either download fan control software or use an external controller device.

How do I check my CPU fan speed?

If you want to keep an eye on your CPU fan speed, then you need to install fan control software such as SpeedFan. After downloading and installing the software into your PC, you will need to launch it. After launching the software, it will get all the data from your PC, and you will be able to check your CPU fan speed.


If you are tired of your PC overheating, lagging, and shutting down, then you need to check the fan speed of your CPU. Adjusting the CPU fan speed without BIOS will not only speed up your system, but it will also reduce the system heat up, which will reduce lag.

I hope this article gives you all the information that you need regarding changing CPU fan speed without BIOS.
