Laptops are a popular choice for people who need to be mobile and have computing power wherever they go. One of the downsides of laptops is that they can overheat if the fan isn’t working properly.

If your laptop fan isn’t working, it’s important to know how to tell so you can take steps to cool it down and prevent damage. This blog post will explain how to tell if laptop fan is working and what to do if it’s not. Stay cool!


1. Examine the fan blades to see if they are moving. If not, the fan is not working.

2. Listen for noise coming from the fan. A working laptop fan should produce a low humming noise.

3. Place your hand near the vent to feel for air movement. If you don’t feel any air movement, the fan is not working.

4. Check the CPU temperature in the BIOS to see if it is reading correctly. If the CPU temperature is high and the fan is not running, this could be an indication that the fan is not working properly.

If you suspect that your laptop fan is not working properly, it is important to have it checked by a qualified technician. A laptop fan not working correctly can cause your laptop to overheat, which can damage the internal components.

Laptop Feel Warm

If your laptop starts to feel warm or hot to the touch, that’s a sign that the fan isn’t working properly. You can also check to see if the fan is running by feeling for airflow from the vents on the side or back of the laptop.

If you don’t feel any airflow, that’s another indication that the fan isn’t working.

Dust And Dirt

If you think your laptop’s fan isn’t working, the first thing to do is make sure that it’s not just a buildup of dust and dirt. The fan can become clogged with debris over time, preventing it from running properly.

You can clean the fan by using compressed air to blow the dust out of the vents. If the fan is still not working after you’ve cleaned it, there may be a more serious problem, such as a faulty fan motor or an issue with the laptop’s thermal management system.

In these cases, it’s best to take the laptop to a qualified repair technician for diagnosis and repairs.


Overheating can damage your laptop, so taking action is important if you think the fan isn’t working properly. Following the tips in this blog post, you can ensure your laptop stays cool and continues running smoothly.

What Is A Laptop Fan, And What Does It Do?

A laptop fan is a cooling device that helps dissipate heat away from the computer processor and other sensitive components. Laptop fans typically have one or two blades that spin to create airflow. The more blades a fan has, the more air it can move.

Laptop fans are important because they help keep the computer cool and prevent it from overheating. Without a fan, the computer would quickly overheat and become damaged.

What To Do If Your Laptop Fan Isn’t Working?

If you think your laptop fan isn’t working, there are a few things you can do to check. First, try opening up your laptop and cleaning the fan with compressed air.

If that doesn’t work, you can try downloading a program like SpeedFan or HWMonitor to check if your fan is spinning. If neither of those options works, you may need to replace your fan.

How To Clean Your Laptop Fans?

The fans in your laptop are important for keeping the components cool and preventing overheating. Over time, the fans can become clogged with dust and debris, reducing their efficiency.

Cleaning your laptop’s fans regularly will help keep your computer running smoothly.

There are a few different ways to clean laptop fans, depending on how accessible they are. If the fans are easily accessible, you can use compressed air to blow away dust and debris.

If the fans are not easily accessible, you may need to open up the laptop to clean them. In either case, it’s important to be careful when cleaning laptop fans.

Use only gentle pressure when blowing air into the fan, and be careful not to damage the delicate blades. When opening the laptop, follow the manufacturer’s instructions carefully to avoid damaging any components.

You can keep your laptop’s fans clean and running smoothly with a little care.
