How to Change CPU Fan Speed without BIOS?

The CPU is the most important component in a computer, and it generates a lot of heat when it’s running. To keep it from overheating, a fan is usually installed on top of the CPU. The fan works by drawing heat away from the CPU and pushing it out of the case. However, the fan can also generate noise, and it may not always be running at the optimal speed. In this guide, we’ll show you how to change the CPU fan speed without accessing the BIOS. By adjusting the fan speed, you can reduce noise and keep your computer cool.

Other methods to change the CPU fan speed without BIOS:

Method 1: Using a Fan Hub or Controller

A fan hub or controller is a hardware device that allows you to control the speed of your fans without accessing the BIOS. To use a fan hub or controller, you’ll need to install it inside your computer case and connect your fans to it. You can then adjust the fan speed using the controls on the hub or controller.

Method 2: Using the Manufacturer’s Software

Some computer manufacturers provide software that allows you to control the speed of your fans. For example, MSI provides the MSI Afterburner software, which can be used to adjust the fan speed on MSI motherboards. To use the software, you’ll need to download and install it on your computer.

Method 3: Using Third-Party Software

In addition to SpeedFan, there are several other third-party programs that can be used to adjust the fan speed on your computer. Some popular programs include:

  • HWiNFO
  • CAM
  • Open Hardware Monitor
  • Argus Monitor

To use these programs, you’ll need to download and install them on your computer. Each program may have a slightly different interface, but they all offer similar features for adjusting the fan speed.

Method 4: Using the BIOS Emulator

If you’re unable to access the BIOS on your computer, you can use a BIOS emulator to make changes to your system settings. One popular BIOS emulator is the Unified Extensible Firmware Interface (UEFI) Shell. To use the UEFI Shell, you’ll need to download and install it on a USB drive and boot your computer from the drive. Once you’re in the UEFI Shell, you can make changes to your system settings, including the fan speed.

Tips for Changing CPU Fan Speed without BIOS

  • Always monitor your CPU temperature when adjusting the fan speed. You don’t want to reduce the fan speed too much and risk overheating your CPU.
  • Start with a small adjustment to the fan speed and monitor the CPU temperature. Gradually increase or decrease the fan speed until you find the optimal setting.
  • If you’re not comfortable adjusting the fan speed manually, you can choose the automatic fan control option in SpeedFan.
