How to Change CPU Fan Speed Without Bios?

The CPU cooler is a critical component in a computer as it regulates the heat that is generated by the central processing unit. When the CPU gets too hot, it can damage or shorten its lifespan. The CPU can get really hot even when your computer is not in use, which means the cooling system needs to be running at all times. If you are overclocking your CPU, you may need to use an aftermarket CPU cooler with more adequate cooling properties.

The BIOS is the device that controls the computer’s hardware and software. The BIOS is accessed by pressing a designated key (usually the Delete key) during start up.There are many ways to change the CPU fan speed without BIOS, but the most effective way is to use the motherboard setting.


What is a CPU cooler?

A CPU cooler is a device that dissipates heat from a computer’s central processing unit (CPU).   You might notice it as a silver, or copper-colored heatsink with a fan on top of it.   This device is typically located on the motherboard and cools the CPU by liquid, air, or both cooling methods. Cooling liquid often goes through the inside of the heatsink to absorb heat from the base of the CPU. The liquid then is passed through the fins of the heatsink and back to the heatsink’s base where the liquid is re-absorbed into the heatsink and used again.

What is the purpose of a CPU cooling unit?

Replacing a faulty CPU cooler with a new one is important to keep the computer running at optimal levels. It also helps to prevent damage to other parts of the computer that could result from an overheated processor. The main purpose of a CPU cooler is to cool the processor and thus ensure that it runs at optimum speeds for extended periods of time.

In this article, we will cover how to change CPU fan speed without BIOS. The methods are listed below:

1. Using motherboard settings

The motherboard settings are important to know for the stability and performance of your PC. The motherboard settings are also necessary for overclocking.

Overclocking is a process by which the CPU frequency, voltage, memory clock speed, or other system parameters are modified in order to increase performance beyond their rated specifications. The motherboard settings can be changed through BIOS or UEFI menus.

2. Using BIOS settings

BIOS settings are used to set up and control the hardware of a computer. There are different menus that can be accessed through the BIOS settings. This article will teach you how to use these menus and what they do.

The first menu is referred to as the Boot Menu. It allows you to change your boot order, which is the order in which your computer boots from its hard drive, optical drive, or network card. This can be useful when you want to make sure that your computer boots from a specific device before starting Windows or if you need to get into BIOS settings for other reasons.

The next menu is called the Advanced Menu, and it has various submenus that allow you to change advanced settings such as CPU configuration, PCI/PCI-Express configuration, CPU Power Management Configuration, and more.

3. Removing and replacing the CPU cooler

We all know that the CPU cooler is one of the most important components in a computer. To remove and replace it, you need to be very careful and make sure that you are not damaging any other components.

Some CPUs come with a built-in cooler, so there is no need to remove it. However, if your CPU doesn’t have a built-in cooler than you will need to remove it before replacing it with a new one.

Removing the CPU cooler should not be done by simply pulling on the wires and cables attached to it or by using your fingers to grab hold of them. Instead, use tweezers or needle-nosed pliers for easier removal of the wires and cables from their sockets.

4. Changing the Voltage of CPU Fan Pins

The voltage of a CPU fan is controlled by the motherboard. The motherboard controls the voltage based on what temperature it needs to maintain for your computer.

A CPU fan will automatically speed up when it gets too hot and slow down when it cools down. When the temperature of your computer changes, the motherboard will change the voltage of your CPU fan to keep your computer at its optimal temperature.

5. Replacing a faulty CPU Cooler with a New One

In order to avoid the hassle of buying a new CPU cooler, some people opt for a DIY replacement. It is important to note that this may cause more harm than good. A DIY replacement for an old CPU cooler may cause more harm than good if not done properly. The following are the common mistakes people make when trying to replace their old CPU coolers with new ones:

1) Using incompatible parts – This is due to the fact that different brands have different specifications and compatibility issues can arise when using incompatible parts.

2) Overclocking or overclocking too much – By overclocking your CPU, you risk damaging it and voiding your warranty.

Changing CPU Fan Settings Manually on Ryzen Chipset Motherboards

There are many ways to change the CPU fan speed on Ryzen motherboards, but most of them require a BIOS setting. However, there is an easy way to manually change the fan settings without a BIOS.

The first step is to go into your motherboard’s UEFI setup and find the “Fan Settings” section. From there, you can set your desired fan speed and make sure that it is enabled by checking the box next to “Enable Fan Control”.


How do I change my CPU fan speed manually?

If you are using a desktop computer, it is possible to manually change your CPU fan speed by going into the BIOS settings and changing the fan control setting. This will vary depending on your motherboard manufacturer. If you are using a laptop, it is not possible to manually change the CPU fan speed.

How do I manually control CPU fan speed on my laptop?

To control your CPU fan speed on your laptop, you can download a program called SpeedFan. This program will allow you to manually adjust the fan speed on your laptop.


Today, you want to learn how to change your cpu fan speed using bios settings or manually. The first option is the most common choice and will be the simplest. The second option is more complicated, but can be worth it if you need to overclock your cpu.
