Laptop Fan Quick Fix Guide

When we run programs on our laptops, the system starts to heat up as the load increases. Laptops use a fan or sometimes multiple fans to keep the core temperature of the system down. The fan inside of our laptop helps keep the airflow going, there are often vents on either side of the laptop from where the air keeps flowing out.

When you first start the laptop, the fan runs at a very slow speed but after the laptop gets to its normal usage, the fan speed begins to climb up and you can also hear the sound of the fan getting louder and louder as the temperature climbs higher. It makes sure that the system doesn’t get overheated which results in the laptop getting restarted or the apps getting crashed abruptly.

How to Figure out the Problem?

If you think there’s some problem with your laptop’s fan but you don’t exactly know what it is. Here are some of the things that you can do to figure out what the problem might be.

Fan Noise

Once you start your laptop, you should be able to listen to a very slow noise from the fan’s propeller. If you can’t listen to it at first just give your laptop some time to get to its normal usage. You can make sure by booting up some of the apps that use more ram and let it run for a few minutes. This should increase the speed of your laptop’s fan and in turn, it should also increase the intensity of sound coming out of the laptop.

If you still can’t listen to the noise of your fan, you should move into some silent room to make sure that you can properly hear it. If you still can’t hear anything, chances are your fan might be broken or not starting at all.
