How to Change CPU Fan Speed without BIOS

A CPU fan is one of the essential components in ensuring that your computer runs smoothly. The ability to regulate the CPU fan will aid in keeping your system cool and silent. When playing games or utilizing demanding applications, you may find that your PC overheats or becomes excessively.

By changing the fan speed on your computer, you can guarantee that it runs smoothly. Most users prefer to alter the fan speed of their CPU in BIOS. It is the most commonly suggested approach, although it does not always work. These solutions could work for you if you’re having trouble slowing down or boosting CPU fan speed. 

Some Methods How to Change CPU Fan Speed without BIOS

The following steps will show you how to change the CPU fan speed without BIOS.

Make use of software that allows you to control your fans.

Even if you can manually adjust your computer fan speeds, it is preferable to choose an automated alternative. In this scenario, you’ll need to utilize fan-control software. An automated fan controller program will keep track of CPU temperatures and, if necessary, alter the fan speed on your PC.

When the CPU becomes too hot, a PC fan controller program will silently raise the fan speed and reduce it when it returns to normal. You can regulate fan speeds using several different programs. Choosing the proper one, on the other hand, should be your first focus. In addition, it would be beneficial to check to see if the program you select is compatible with all operating systems, including Windows 10.

SpeedFan Software

It is one of the essential software to change the CPU speed without BIOS. If your PC’s BIOS doesn’t enable you to switch fan speeds, you can use SpeedFan instead. It’s one of the free programs that let you manage your CPU fans in greater detail. SpeedFan has been around for a long time and is still the most popular fan control program. SpeedFan, despite its popularity, is a little more advanced for novices.

If you are not a seasoned user, it may take some time to get the hang of it. If you make a mistake while using this program, it may cause harm to your hardware. Also, SpeedFan isn’t compatible with every computer. Double-check that it supports your machine’s chipset. 

Here are some of the steps you should take to use SpeedFan to regulate your fan speed.

a. Download and Install SpeedFan 

To use SpeedFan, go to the official website and download the most recent version.

Once the download is complete, please install the program as usual and wait for it to begin.

Allow the software to scan your computer and display all relevant information in the main window.

The primary window displays the fan RPMs, as well as temperatures for your CPU, motherboard chipset, graphics card, hard disc, and other components.

Make sure you familiarize yourself with the various labels to know what they symbolize or stand for. If you’re not sure about the settings, don’t mess with them. 

b. Play with Some Fan Controls

SpeedFan is a little challenging to use. Fortunately, you can select “Automatic Fan Speed” to have the program automatically regulate your system.

This option may not always give satisfactory results, which is why you should experiment with different fan settings.

To begin, pick the advanced tab after clicking the Configure option. Next, click the “Chip” dropdown menu to select your motherboard chipset.

After that, make sure all of the PWM Mode choices (PWM 1 mode, PWM 2 mode, and PWM 3 mode) are set to “MANUAL.”

Would you please make sure the Remember it the box is checked and click the OK button?

c. Set Up Your Automatic Fan Control

After selecting the Configure button, go to the “speeds” page to specify the minimum and maximum RPM for your fans.

Once you’ve got that figured out, go to the Fan Control tab and create an optimum temperature curve for your CPU fan.

This phase will assist you in determining whether or not the adjustments you’ve made have had any effect. You may run any demanding program to see how well these modifications work.

Make careful to save all of your changes; otherwise, you’ll have to do it all over again every time you restart your computer.

Finally, go to the “Temperatures” section to control when your CPU fan speeds up or slows down, depending on how hot it becomes.

Make sure you choose the sensor that will regulate your CPU fan. When you look at this sensor, you’ll see two options at the bottom of the display.

Set the “Desired” and “Warning” temperatures with the arrow buttons now. When you’re finished, click OK.

In SpeedFan, this is how you alter the Fan speed. Keep in mind that this program may not be compatible with all PCs. If SpeedFan does not work on your machine, you can try the next option.

Use Some Other Software to Change The CPU Speed Without BIOS

You can also try some other software to change the Fan Speed if you are not working with SpeedFan. Below is enlist some other software to change the Fan Speed without BIOS.

Open Hardware Monitor Softwares

Another excellent software option for controlling the speed of fans in Windows 10 is Fan Control. This program is compatible with the newest versions of monitoring hardware chips.

On the desktop system, you can customize them. It investigates the CPU temperature and cold temperature of AMD and Intel processor sensors.
