Most Laptop use fans to cool components like CPU, GPU and motherboard by sucking in the cold air and expelling hot air through the vents. If your laptop fans are broken or not functioning at all, they could lead to problems likeoverheatingand shutdown. Furthermore, your laptop may thermally throttle which will degrade its performance and shorten its lifespan.

Issues in fans arise due to reasons such asdust and dirt build-up. Or, sometimes the problem with the software side of things can also lead to this issue. You can resolve this issue by cleaning the fans and addressing mechanical failures that may need repairs or replacement.

This guide will give you insight on what may be causing your laptop fan to not work properly and how you can fix them.

Probable Causes of The Issue

Fixes for Laptop Fan Not Working

There are several ways to fix the issue of Laptop fan not spinning. However, some manufacturers discourage users from repairing their devices by themselves or third-parties. This may void the warranty of your device. Please consult your device manufacturer or check their information page for details.

If you are in a position to get it repaired yourself, you can try these solutions to fix this issue.

Run Hardware Diagnostics or Troubleshooter

If your device has a faulty update, missing drivers, or installation of incompatible software, your fans may not receive proper operational instructions. This issue will cause the fans on your device to malfunction or cause them to not work at all.

For the user’s convenience, most laptops nowadays are equipped with troubleshooters and diagnostic programs that address hardware issues. They detect and isolate issues by performing scans and tests.

To perform a diagnosis from Windows, follow these steps:

you may alsorun the hardware troubleshooterinstalled by your device’s manufacturer. Check the instruction manual provided or go to the manufacturer’s website for detailed information on how to  access the diagnostic software.

If any problem is not detected by the program, you can perform the following fixeslisted below.

Reinstall or Change BIOS Settings

BIOS is the firmware that helps to control the operation of the fans in the system. If you have recently updated, reinstalled, or made any changes to your BIOS, check if the settings of your fans have been reset or disabled.

Toenter BIOS from Windows, hold the “Shift” key and restart your laptop. This will boot your device into recovery mode. From here, follow these steps:

Note:Updating or flashing BIOS is a risky procedure. A failed BIOS install can make your device unusable. Make sure your device is connected to a charger before proceeding.

Update Device Drivers

If the issue is because of device drivers, you canupdate the device driversand check if it solves the issue of overheating.

Here’re the steps to update your drivers:

Change Fan Control Software Settings

Fan control software helps users fine tune at which temperature and speed the fan operates. It may come prepackaged with your device from the manufacturer or installed later by the user.

If your device has any fan control software installed, it may be causing interference with your laptop’s fans from receiving proper instructions. Incompatiblefan control softwarecan also trigger the fans to behave erratically causing them to malfunction or cease completely. To fix this,

The fixes are specific to the fan control software. Check the software manual for details on how to change settings or remove them.

Check for Any Loose or Broken Connections

Laptop fans receive power from the motherboard. The headers that connect the fans to the motherboard may be wobbly or unplugged if your device has had any kind of impact or accident. Wires that carry power to the fans may also be damaged, loose, or broken.

To check for any loose and/or broken fan connections, firstly:

Note:Do not attempt to solder components without first having a proper schematic, circuit diagram, or information of the motherboard. You may accidentally further damage your device by short-circuiting the leads or burning the circuits.

Before attempting any kind of hardware fix, make sure you are comfortable with opening the housing covers and working on your laptop. Most hardware faults require disassembly for inspection and repairs.

Screwdrivers, pry tools, soldering materials, and cleaners are required to repair and clean the necessary parts of your laptop. Do not force open a laptop or attempt any repairs without proper tools and instructions beforehand.

Clean the Fans

The fans of a laptop are designed to keep your device cool by allowing air to flow through and out of the device. Using your laptop in an area without sufficient airflow can cause the vents to get blocked by accumulation of foreign particles. To keep your laptop cool, the fans run much faster which further damages them or render them useless.

Depending on the model, your laptop may have more than one fan. More powerful and capable laptops have more fans. They are usually separated for components like CPU (Central Processing Unit) and GPU (Graphics Processing Unit) because theyproduce the greatest amount of heat.

If your laptop has more than one fan, ensure to differentiate which fan cools which component before disassembling.

To clean the fans of your laptop, follow thses steps:

When cleaning your fans using compressed air, make sure that they are held down so that they do not spin. This step is to protect your fans from spinning too fast and damaging any components of the fan.

If you are using Isopropyl alcohol or any solution to clean your fan components, make sure that they are safe for electronics.

Note:After disconnecting the battery, drain your device completely from any remaining power by pressing the power button for 10 seconds. This is to ensure the laptop will not short circuit when using liquids to clean the fans.

Replace Any Broken Components

The components inside a laptop are prone to damage by shock, impact, or any sudden motion. Fans and other moving parts like hard disks are even more susceptible.

If the blades, bearings, or any component of your fans are broken, they need to be replaced. A broken fan component may cause more damage to your device’s internal parts by further breaking apart.

Wires, cables, and connectors need to be replaced if you do not have the necessary tools to fix them. Any damaged or torn-off components should also be either replaced or repaired as they may cause a faulty connection or short circuit the device.

How to Maintain the Health of Your Laptop’s Fans?

Moving parts like fans need to be serviced regularly to maintain performance and prolong usage. Your device also becomes less prone to issues and damages. You can maintain the health of your device’s fans by performing the following tasks:

These are some of the methods you’re able to use to fix the fans on your laptop. If you are unsure or have doubts, please contact your device manufacturer or technician and send it for repairs.
