Since the release of Windows 11, many users have complained about many things after upgrading to Windows 11. One of the complaints is the PC or laptop fan is always running. Even when the PC is off the fan keeps running and making loud noises.

It is both annoying and worrisome. But we’re here to make those worries go away and show you how you can fix if the fans are always running after upgrading to Windows 11. But first, let’s learn about the causes so that you can prevent them from happening again.

What Causes the Fans to Always Run in Windows 11?

There could be many reasons why the fans on PC are always running. Some of the most common reasons why this happens are:

• Overheating.
• Overclocking.
• Dust accumulation.
• Insufficient ventilation.
• Physically damaged CPU.
• Outdated BIOS and device drivers.

These can be fixed but some need to be monitored from time to time. Most importantly overheating and dust accumulation should be the ones to look out for.

How Can You Fix It if The Fan Is Always Running in Windows 11?

Unfortunately, Windows 11 doesn’t have a built-in program to monitor or control the fan speed. But there are other options with which you can fix the issue of the fans running continuously. Here are the fixes that we think will help you in this scenario:

Fix 1: Control Overheating

Computer fans are there to control the heat that generates from different parts of the PC. But sometimes fans can’t always keep up with the amount of heat the PC generates. If this happens, you can try to lower the settings of different programs such as power settings, graphics settings, etc. These will help reduce heat generation.

You can also try replacing the thermal paste on your CPU. Thermal paste specializes in controlling the heat generation of the CPU but it needs to be replaced every few years. Check to see if the thermal paste on your CPU has dried up and needs replacement.

Fix 2: Run Windows Troubleshooter

One of the things that could help fix the fan always running issue is the Windows troubleshooter. Since the fan is always running, it could be because of a hardware or power issue. And to fix such issues, run the troubleshooter for Hardware & Devices, and Power so that all potential problems can be fixed.

Fix 3: Disable Modern Standby

If your PC fans are running while it’s in Sleep mode, it could be because of the new S0 and S1 sleep states. Modern systems, which mostly include laptops, are configured with a new sleep state as the default. It is known as S0 sleep state or Modern Standby.

Modern Standby provides a smooth on-and-off experience that works like a mobile phone screen locking and unlocking. But it also has drawbacks such as the CPU fan running all the time. And since this can create problems in the future, you will need to disable this setting and revert to the S3 sleep state that allows the CPU and CPU fans to turn off.

To change the settings for it, you will need to go into your system’s BIOS. Unfortunately, we can not provide you with a step-by-step process of it since the BIOS interface depends on the motherboard manufacturer. Generally, these settings are located in power management and suspended mode so you should start there.

Fix 4: Update BIOS

The system BIOS controls and regulates the fans; an outdated BIOS cannot do that properly. Hence, you will need to update the BIOS.

To update the BIOS, you will need to go to the manufacturer’s website > find and download the latest BIOS > open the file > follow on-screen instructions, and complete the update. After completion, you will be asked to restart the computer and you should do so.
