Your laptop’s fan is responsible for keeping the internals cool and functioning properly. Over time, the fan can become dusty and clogged, diminishing its ability to do its job. Additionally, thebearings in the fan can wear out, causing it to make noise or even fail completely. In this article, we’ll show you how to check your laptop’s fan health so you can keep an eye on it and know when it needs to be cleaned or replaced.

What are the symptoms of a failing laptop fan?

The fan in your laptop is responsible for keeping the internal components cool. Over time, the fan can become dust-clogged or simply wear out, causing it to run less efficiently and eventually fail. While you might be able to clean a dusty fan, it’s generally best to replace a failing fan with a new one.

There are several symptoms that can indicate a failing laptop fan:

-The laptop runs hot and the fan is constantly running.
-The laptop randomly shuts down due to overheating.
-There is physical damage to the fan, such as bent blades.
-The fan makes strange noises, such as grinding or squeaking.

How to check the health of your laptop fan

There are a few signs that indicate your fan needs some attention:
-Your laptop sounds like it’s about to take off
-Your laptop overheats quickly
-Your fan is always running

Here are three ways to check the health of your laptop fan and see if it needs to be cleaned or replaced.

1. Check the air vents
The first place to look is the air vents. If they’re blocked by dust, hair, or other debris, your fan won’t be able to do its job properly. Use a can of compressed air to clean out the vents, being careful not to spray too close to the fan blades.

2. Listen for strange noises
If your fan is making strange noises, it might be time for a cleaning. Turn off your laptop and use a can of compressed air to remove any dust from the blades. If the noise persists, it could be a sign that the bearings need to be replaced.

3. Check for thermal throttling
Thermal throttling is when your CPU slows down to prevent overheating. This can cause your laptop to feel slow and sluggish. To check for thermal throttling, download and run a CPU stress test program like IntelBurstWatch or ThrottleStop. If you see your CPU speed dropping during the test, it’s likely that thermal throttling is occurring.

What to do if your laptop fan is failing

If you think your laptop fan isn’t working as it should, it’s important to figure out the issue before it causes any long-term damage. Here are a few signs that your laptop fan may be failing:

1. Your laptop is overheating frequently or shutting down unexpectedly.

2. Your laptop is making unusual noises, especially grinding or whirring sounds.

3. The airflow from your laptop’s vents feels weaker than usual.

If you notice any of these signs, there are a few things you can do to try and fix the problem:

1. Make sure that the vents on your laptop are not blocked by anything. If they are, clear the area around them so that air can flow freely.
2. Check for any dirt or dust buildup inside the vents or on the fan blades themselves. If you see any, use a can of compressed air to blow it out.
3. Try running a program like CPU-Z to monitor your CPU temperature and see if it’s getting too hot when you’re using your laptop. If it is, you may need to apply new thermal compound to the CPU and/or add additional fans to help cool it down.
4. If none of these solutions seem to work, then you may need to replace your laptop fan entirely. This is generally a pretty easy repair that you can do yourself, but it will void your warranty if your laptop is still covered by one.

How to prevent your laptop fan from failing

Laptop Fan health is important to maintain in order to keep your computer running cool and quiet. There are a few things you can do to prevent your laptop fan from failing, such as Dusting out the vents and using an external cooling pad.

If your laptop fan does fail, you’ll want to know how to check laptop fan health so you can replace it as soon as possible. To do this, use a can of compressed air to blow out the dust from the fan blades and bearings. You should also check the voltage and amperage of the fan motor with a multimeter. If the readings are outside of the manufacturer’s specifications, then the fan needs to be replaced.

Laptop fan maintenance tips

You may not think about it often, but the fan inside your laptop plays a crucial role in keeping everything running smoothly. Over time, though, dust and other debris can build up and cause your fan to slow down or even stop working altogether. That’s why it’s important to know how to check the health of your laptop fan and clean it if necessary.

There are a few different ways to do this, but perhaps the simplest is to just download a piece of software like Speccy or HWinfo32. Once you have one of these programs installed, open it up and take a look at the “Fan Speed” reading in the “CPU” section. If everything is working as it should, you should see the fan speed increase when your CPU usage goes up.

If you don’t see this happening, or if you notice that your CPU usage is high even when you’re not doing anything strenuous on your laptop, there’s a good chance that your fan is either clogged with dust or isn’t working properly. In either case, you’ll need to open up your laptop and take a look inside.

Before you do anything else, make sure to power down your laptop and unplug it from any power source. Then, flip it over and remove any screws that are holding down the panel that gives you access to the internals. Once you have that off, take a can of compressed air and give the area around the fan a good blast. This will remove any dust or debris that may be causing problems.

If that doesn’t seem to help, or if you want to be extra thorough, you can also try removing the fan entirely and giving it a good cleaning with some rubbing alcohol. Just be careful not to damage any of the surrounding components in the process.

Once you’ve done all of that, put everything back together and see if things are running any better. With any luck, your laptop will be good as new!


In conclusion, it is important to check your laptop fan health on a regular basis. By doing so, you can ensure that your laptop is running smoothly and avoid any potential issues.
