How to Change Fan Speed Windows 11: A Step-by-Step Guide

Changing your fan speed in Windows 11 is easy once you know where to look. In just a few quick steps, you can adjust your computer’s fan settings to suit your needs, whether you want to cool down your system or reduce noise.

Step by Step Tutorial to Change Fan Speed in Windows 11

Before you start tinkering with your fan speed settings, it’s important to understand that adjusting these settings can affect your computer’s performance and longevity. The steps below will help you change your fan speed safely and effectively.

Step 1: Access the BIOS or UEFI settings

Restart your computer and enter the BIOS or UEFI settings by pressing the appropriate key during startup (usually F2, F10, Delete, or Esc).

The BIOS or UEFI is the basic input/output system or the unified extensible firmware interface of your computer. It’s the software that checks the hardware is working and starts up the operating system when you turn on your computer.

Step 2: Navigate to the Hardware Monitor or Fan Control Settings

Look for a tab or section labeled "Hardware Monitor," "Fan Control," "Thermal," or something similar.

Each BIOS or UEFI interface is slightly different, depending on your motherboard manufacturer. You may need to explore a bit to find the right section.

Step 3: Adjust Fan Speed Settings

Use the fan control options to set your desired fan speed. You can often choose between different modes or manually set a specific fan speed percentage.

Be cautious when adjusting fan speeds. Setting them too low might cause overheating, while setting them too high can create unnecessary noise.

Step 4: Save and Exit BIOS or UEFI

After adjusting your settings, save your changes and exit the BIOS or UEFI. Your computer will restart with the new fan speed settings applied.

Remember, if you’re unsure about the changes you’ve made, you can always reset to default settings within the BIOS or UEFI.

After completing these steps, your computer’s fan speed will be adjusted according to your preferences. You should notice a difference in the system’s cooling performance or noise level, depending on the changes you’ve made.
