The laptop is one of the most popular gadgets that people have at their disposal. It’s lightweight, you can use it for anything from sending emails to watching movies on Netflix, and it can even play games with you. But this convenience has a downside: laptops are notorious for overheating.

The problem is that your laptop fan might not be working correctly if you notice any of these signs:

1) You hear an unusual amount of noise coming from the device

2) The computer shuts down unexpectedly

3) The CPU fan emits a burning smell

4) There are excessive amounts of heat coming out from underneath the machine

5) Your battery lasts less time than usual or shuts down when not connected to a power supply

6) You see warning messages about overheating

If you’re worried about your laptop fan speed, there are a few things that you can do to check if it’s working or not. In this article, we offer three ways to do so. By checking the computer fan regularly could save you from an expensive repair bill!

Why Care About Your Laptop Fan?

Laptop fans are critical for the well-being of your device. They keep your laptop cool, so it doesn’t overheat and shut down, which would be detrimental to your work.

The cooling fan is an internal part that sucks in cold air through air vents, circulates the vital components, and throws it back out faster, so your laptop stays at a safe temperature. But if it gets blocked, the internal components of your computer can quickly overheat.

Laptop Fan Repair

An overheated laptop can lead to loss of data, an expensive repair bill, and complete hardware failure because of damage to the motherboard. If you’re using it for work, an overheated laptop could lead to loss of money or precious time that you need on a project.

So, by checking the fan is working correctly, you can avoid all those risks and keep your laptop in good condition.

How to Check Laptop Fan Performance

There are a few ways you can check if your laptop fan is working correctly. Here we offer three different methods, so choose which one works best for you!

Method 1: By Listening to the Fan’s Sound

One of the easiest ways to find out whether or not your laptop fan is working correctly is by paying attention to its sound. Remember, a noisy fan is terrible news!

The best way to do this is in silence, so it’s easier to hear the noise coming from the fan inside. Make sure all your other applications are closed, and then put your laptop on a flat surface with the bottom facing up.

Place your ear close to the laptop. If you can hear the sound, then your fan is working correctly. But if you don’t hear anything, it could mean that the fan needs to be replaced. The CPU fan speed is quicker under heavy processing, so load up a game or HD video and check if the fan is working. You may be able to feel the CPU temperature rising, which would be an indication fan speed is too high or it’s not working at all. In some cases or older machines, you will hear fan noise inside.

Method 2: By Checking Air Coming Out of Your Vent

Another way to check whether or not your laptop fan is working correctly is by checking for air coming out of your vent.

The laptop fan usually emits air out of the laptop’s vents located at the back or side of the device, so that’s where you should look first. With this method, place your computer on a flat surface, then put the back of your hand close to the exhaust ports. You should feel some warm (or hot!) air, which indicates the fan is working.

If that’s not the case, this method is a quick way to determine whether your fan could be faulty.

Method 3: By Using Fan Control Software Applications

This is an easy and efficient way of checking your laptop fan. There are applications available on the internet that can display information about your machine’s hardware. If you download and install one of these software, you can see if CPU usage is high and faster fan speed. This shows that your laptop fan (if working correctly) must be kicking in to cool down your machine and keep it from overheating.

By checking regularly, you will be able to diagnose issues with your laptop’s fan quickly. Fixing the fan is an easy, fast, and cheap operation if your computer isn’t under warranty anymore. By using a temperature sensor, you can prevent damage and promote a good CPU temp.

For Windows devices, you can install SpeedFan, Real Temp, or HWiNFO, which will provide an array of information about how well your laptop is performing. You can control them better when you know how well they are working. As a general rule of thumb, anything above 158 Fahrenheit is a cause for concern.

iStat Menu is the best option for your Mac device as this enables you to see the big picture regarding fan speed control and general health and performance.


So that’s how you check if your laptop fan is working correctly. If the cooling fan isn’t working by any chance, it could indicate hardware damage because of overheating. That would require you to open up your laptop and investigate further.

Of course, this doesn’t mean that all fans are soundless. If you use your laptop regularly, you can expect to hear some noise coming from it. It’s just that there shouldn’t be an unusually high pitch sound or a crackling sound.

To prolong the life of the fan, using a laptop cooler is highly recommended. A cooling pad is specifically designed to promote good airflow, which prevents the CPU processor from overheating and overworking the GPU fan.

With all these three methods, you can keep your laptop running smoothly and know if the fan is working or not. This way, you’ll be able to notice any complications before they become significant issues.
