How to Configure CPU Fan Speed

The CPU fan is a critical part of your system.

The CPU fan inside your computer is the cooling unit for your PC's processor. It ensures the processor does not overheat and damage itself during operation. Many users choose to change the speed at which this fan operates. Slowing down the fan speed lowers the noise coming from the computer tower, while speeding up the fan provides cooler temperatures for overclocked CPUs. Adjusting the fan speed is done through the BIOS options of the motherboard.

Instructions

1. Restart your computer.

2. Read the BIOS boot messages that appear at the bottom of the screen during restart. This message will state which key you need to press to enter the setup area. Typically, the key is either "F1," "F2" or "Del." Press the correct key to enter the Setup area.

3. Navigate through the BIOS menu using the arrow keys of your keyboard. Move to the section titled "Hardware Monitor" and press the "Enter" key.

4. Move to the option "CFU Fan" using the arrow keys and press "Enter."

5. Adjust the CPU fan speed. Choose one of the built in speed settings for your fan. Highlight "Auto," "Silent" or "Maximum" using the arrow keys, and press "Enter" to select the option you want.

6. Save your new configuration. Press the "F10" key to keep the changes you made and exit BIOS.

Tips & Warnings

• Always use caution when changing any settings in the BIOS menu, as these changes can affect on your PC's performance.
