If your PC is overheating, you need to speed up the CPU fan to keep the system cool. But sometimes the fans could not run at the maximum throttle for unknown reasons. Or you may want to reduce the current speed to save on power or just to reduce the noise, you choose!

But how do you do that, especially if you don’t want to mess up with the BIOS of your computer? How to change CPU fan speed without BIOS?

You can make use of an external fan controller module, or a CPU and peripheral controller software capable of doing this. Well, no worries, I’ve broken down the process of how you use either of the processes with detailed guidelines below.

Let’s help you lower or increase the CPU fan’s speed in seconds without tweaking the BIOS or turning off the computer in the first place.

What Is BIOS?

BIOS stands for Basic Input/ Output System, a vital piece of technology that determines the core variables of a computer. It is a vital startup system built in the core processor software to boot up a computer. The system is integrated with the motherboard chip to catalyze the entire PC function. A BIOS program is also an intermediary between the operating system and hardware.

BIOS is responsible for managing sensitive data flow between the connected devices and operating systems. It determines how a mouse, keyboard, and hard drive operate. Changing something in it or resetting BIOS can affect the way your computer works and how it behaves with the OS and other system software.

Can I Change My CPU Fan Speed Without BIOS?

CPU fan is an essential component on a computer or laptop since it helps the system cool down due to overheating and stay calm. But the overheating problem can overwhelm the system due to unknown reasons.

Can I Change My CPU Fan Speed without BIOS

So, can I change my CPU fan speed without BIOS? Yes. You can install dedicated software programs on the PC or laptop to control the CPU fan speed. Most of these BIOS fan speed control software is straightforward to use.

CPU fans are vulnerable to dust and dirt clogging that inhibits fresh air circulation in the entire computer system. Adjusting BIOS fan setting through certain applications in the computer will help enhance smooth running and operation.

Keep reading this article to learn ideal ways of changing CPU fan speed without BIOS. You will also discover suitable ways how to adjust the CPU fan speed without seeking assistance from a professional computer technician.

How to Change CPU Fan Speed Without BIOS

BIOS program forms the easiest platform to change PC fan speed. But if you want to control CPU fan speed without utilizing the BIOS, use any of the following effective strategies:

How to Change CPU Fan Speed Without Bios

Use External Fan Controllers

An external fan controller forms an easy way to speed up your CPU fan. These fan controllers have a wide range of options in regulating the CPU fan speed of your entire system. External fan controllers allow the computer user to check the CPU temperature before switching on or off the cooling fans. They also help to increase or decrease the CPU fan speed.

Use External Fan Controllers

Be sure to purchase an external fan controller compatible with your bios fan setting. A perfect external controller will keep your system calm and cool without using bios.

Use Fan Control Software

Installing fan control software will help increase or decrease the CPU speed without bios. It is an authentic option to control the CPU temperature. The application will automatically increase the CPU fan speed if it gets heated and decreases when the temperature gets back to normal.

Choose fan control software compatible with the PC operating system. Otherwise, it will be challenging to control CPU fan speed from your computer.

Use Fan Control Software

The most reliable fan control software for computers or laptops is SpeedFan, Open Hardware Monitor, NoteBook FanControl, and Zotac FireStorm. Each of these fan control applications come with their advantages and disadvantages. I recommend researching more on each to make an informed decision.

Remove the Cover

Most CPU fans require free straight development for introducing a regulator. It is a point where a DVD or Blu-beam drive is introduced. Stick to the PC manual guidelines to remove the cover in the accessible drive-cove extension opening and introduce the fan regulator.

Interface the Warm Sensor

A few fan regulator brands have a warm temperature sensor input feature. I recommend disengaging the warm sensor input from the motherboard and connecting it to the fan regulator.

Follow the manufacturer’s manual to introduce the fan regulator efficiently and effectively. It will help increase or decrease the CPU fan speed when the need arises.

Interface Force Supply to the Fan Regulator

The interface capacity to the fan regulator will depend on the type. Some fan regulator types have a force input where an individual can interface a link from the force supply. If you want to utilize one of the association links on the fan regulator, interface it to the fan yield associated with the CPU fan speed on the motherboard.

A few fan regulators may require connectors to associate the link with the force supply on the rear fan regulator. The purpose is to ensure the average CPU fan speed is achieved.

Test the Fan Regulator

Test the CPU fan speed by utilizing the fan regulator before making final changes. Remember to consult the manual guidelines in case the BIOS fan setting isn’t working. If you have a faulty CPU fan that persists not be in order, consider a CPU fan removal to replace it with a better one that offers proper software control right out of the box.

Assemble the PC Back

If the CPU fan settings are working well, feel free to set up your PC back. Ensure you can access the fan regulator extension input and secure it with screws. Reattach the side cases of your PC and secure them by utilizing the screws.

Frequently Asked Questions

What is a good fan speed?

The average CPU fan speed should range from 50-70% of RPM when the computer is in casual usage. But if you are undertaking heavy 3D projects, set the CPU fan speed at 100%.

What causes a computer fan to speed up?

Increase in CPU temperature due to maximum utilization by heavy games and video editing applications will make the computer fan to speed up. It helps the machine be in optimal temperature so that you don’t face an unfortunate shut-off or worse, damage to the machine!

How do I know if the CPU fan is working properly?

Visually inspect the computer to see if the fan is rotating in the case back. If the fan isn’t rotating, replace it immediately to avoid ruining your computer. If you leave a CPU without a fan keeping it cool, you’ll end up frying things up inside the box and won’t be able to keep running the PC for a minute at a pace.

How do I change my CPU fan speed manually?

Most computers have different motherboard features since it depends on the manufacturer. Below are quick steps to change the CPU fan speed manually:

  • Restart the pc and wait for the power-on self-test startup screen to appear. Enter the BIOS by pressing the button display onscreen.
  • Use the keyboard arrow keys to scroll through the BIOS menu to the monitor status. Choose the fan speed control option to open the fan control settings.
  • Select the fan speed control section and choose the desired speed by pressing enter. Press the enter button again to save the desired fan speed.

How do I adjust my CPU fan speed windows 10?

Every computer has an inbuilt fan to help it cool down when it heats up. The CPU fan runs fast when the system is boot up and slows down when the startup completes. If you want to adjust the CPU fan speed in a Windows 10 operating system, I recommend using reputable control fan speed software. Follow the steps in the software to speed up your CPU fan.

Conclusion

I hope this guide has helped you learn how to change CPU fan speed without bios alterations. If you find it still challenging, seek professional computer technician assistance. Remember that different computers have different properties when it comes to fan settings.

Choose fans compatible with your laptop or PC to adjust the CPU fan speed using dedicated software, often packed out of the box. Most of these fan speed control software is ideal for multipurpose computers. It helps the system dissipate the heat and avoid overheating issues.
