Fortunately, alternative ways exist to change CPU fan speed without entering the BIOS. In this blog post, we’ll explore some easy and effective methods that will help you optimize your system’s cooling while keeping things quiet and seamless.

If you want to change the CPU fan speed without using a BIOS, there are a few things that you will need to do. The first thing that you will need to do is enable fan speed control in your computer’s BIOS. This can be done by entering the CMOS setup menu and navigating to the “CPU” tab. Under “Change CPU Fan Speed Control,” ensure the “Enable Fan Speed Control” checkbox is checked.

Then, adjust the fan speed by using the up and down arrows on the fan speed controller. Be sure to restart your computer after making any Change CPU Fan Speed. Another option for changing the CPU fan speed without a BIOS is using a third-party software program. Some programs allow you to adjust the CPU and GPU fan speeds.

However, read the program’s instructions before using it, as not all programs are compatible with all computers. Finally, if neither of these methods works for you or your computer, you may need to contact your computer’s manufacturer for assistance.

What is CPU fan speed?

Change CPU Fan Speed circulates air around the CPU and keeps it cool. The motherboard’s BIOS controls the fan speed, which usually defaults to a low speed. If the CPU temperature gets too high, the BIOS can increase the fan speed to help cool down the computer.

How to change CPU fan speed without bios

If you want to change the fan speed on your computer without resorting to the BIOS, you can use a few methods. The first is to adjust the CPU fan settings in the operating system. You can find this under “Control Panel” > “Hardware And Sound” > “System And Security” > “Performance And Maintenance” > “CPU Fan.” You must identify your motherboard’s fan header and set the desired speed.

If your computer doesn’t have a CPU fan header, or if it’s not accessible from the operating system, you can also use an application like Change CPU Fan Speed to control fan speeds. To do this, open the application and click the “Fan” tab. Next, locate your motherboard’s fan header and click on it to open its properties. Under “Speed,” set the desired speed for your CPU fan. Be sure to check “Apply To All Processors.”

Benefits of changing CPU

If you are experiencing problems with your computer overheating, it is likely that the fan speed is not set correctly. In this article, we will show you how to change the fan speed on a Mac using a few simple steps.

First, open System Preferences by clicking on the Apple logo in the top left corner of your screen and selecting “System Preferences.” Once System Preferences has opened, click “Energy Saver” in the left column.

Next, click “Fan Speed” in the row beneath “Energy Saver.” You will see three fan speeds: Low, Medium, and High. The default setting for this menu is “Low.” To change the fan speed, drag the slider to the desired position and release it.


Note that if your computer is overheating frequently, even when the fan is set to Low, you may need to increase the fan

CPU fan speed is the number of times per minute the change CPU fan speed spins. The higher the fan speed, the more air the fan will move, and the faster it will cool down the CPU. However, increasing CPU fan speed can also cause noise and increase your computer’s temperature.

You can change CPU fan speed without bios by following these steps:

  • Shut down your computer and unplug it from power. If you have a laptop, remove the battery.
  • Open your computer’s case. You’ll need to remove screws on some computers to get to the motherboard. On other computers, you’ll need to pop off the cover.
  • Locate and identify your CPU. It may be called “CPU,” “Central Processing Unit,” or something similar.
  • Locate and identify your Fan Controller Board (or Fan Speed Regulator). It may be called something similar to a “PCI Express controller.” 
  • Find and open a socket on your motherboard that matches the connector on your Fan Controller Board (or Fan Speed Regulator). There may be multiple sockets, so look for one close to your CPU is location but not connected to anything else yet.
  • Connect one end of a length of wire (about 6 inches should do it) to each of the two connectors on your Fan Controller Board (or Fan Speed Regulator). Make sure they’re firmly connected!
  • Push the wire connector

speed by moving it up one level. If you experience continued overheating even after raising the fan speed to High or Very High, your computer likely requires further repair or replacement.

Fan speed without Bios

The benefits of changing CPU fan speed without Bios depend on the individual user’s needs and preferences. For some, a faster fan speed may provide better cooling performance. Others may prefer a quieter environment and choose a slower fan speed to preserve quietness. Some users may want to change the fan speed based on the motherboard’s default settings.

If you want to change the CPU fan speed without using the BIOS, there are a few different ways. You can use the Windows 7 power options or the Linux command line. The first way is to go to the power options in Windows and set your fan speed as desired. The second way is to use the Linux command line, which has many more options for controlling your fans.

How to change fan speed in Windows

In Windows, you can change the fan speed by opening the “System Properties” window and clicking the “Hardware” tab. You can select your computer’s hardware components and adjust their fan speeds from here.

To change the CPU fan speed on a laptop or desktop computer with a built-in fan, turn off the power to the computer (if it is powered on) and then open the battery compartment. Remove the battery if there is one, and flip over the laptop or desktop so the fans are facing down. Use a Torx screwdriver to remove four screws that hold the housing in place, two on each side of the computer. Lift the housing and set it aside.

You will now be able to see and access the fan blades. To change the CPU fan speed, first, use a flathead screwdriver to remove one of the two screws closest to where you removed the housing (see illustration). This will allow you to rotate the blade 180 degrees. Reattach the screw and replace both screws before reassembling everything in reverse order.

Change CPU Fan Speed

Be sure to test your new speed setting by turning on your computer and pressing any key to bring up a boot menu. If all goes well, replace your old battery and assemble everything.

How to change fan speed in macOS

In MacOS, you can change CPU fan speed by clicking “System Preferences” and clicking “Hardware”. There, you will see a tab called “Fans”. You can change the fan speed by selecting a different value from the dropdown menu.

To change CPU fan speed without Bios on your Mac, you must first access the “System Preferences” app. From here, click on the “Hardware” tab and select the “Fan Speed” slider. You can now adjust the fan speed to your desired level.

Change CPU Fan Speed Without Bios

If you’re having trouble changing CPU fan speed without a BIOS, you can try a few things. First, ensure your computer is properly configured and installed with the correct hardware. Sometimes hardware issues can cause problems when changing fan speeds in bios.

Second, if the problem persists after those basic troubleshooting steps have been followed, it might be time to take your computer in for repair or replacement. If neither of those options works and you still want to change CPU fan speeds without a BIOS, consider upgrading your motherboard to one that includes support for advanced fan controls.
