Reasons why laptop fan makes noise

Unlike other electronic devices, laptops tend to have a single-functioning fan. So it’s very easy to locate where the sound is coming from. The fan is located at the bottom left of the laptop’s base. There can be multiple reasons why your laptop’s fan is creating an irregular sound. Here is a list of reasons why your laptop may be creating noise.

  • Overheating
  • Dust
  • Blocked ventilation
  • Improper surface
  • Malware

1. Overheating: 

Overheating a laptop is one of the most common ways a laptop’s fan tends to make noise. Running too hot during usage can make your laptop fan run faster, hence, creating a greater, irregular sound.

2. Dust: 

Dust is another considerable factor that makes your laptop’s fan create noise. The dust blocks the area around the fan and makes it begin to rattle. Dust can harm the functionality of your device’s fan if blocked for a longer time.

3. Blocked air vents: 

The Air ventilation system located in a laptop can be blocked by the presence of excessive dust gathered in the vents. The dust ceases the fan’s movement and makes it resist functioning. The resistance, in turn, is fought by the laptop’s fan through excessive force- in this situation, the rattling or grinding sound is created.

4. Improper Surface: 

The place you put your laptop during usage can also affect the functioning of its fan. An uneven surface creates higher chances of a laptop’s fan dysfunctioning.

5. Malware: 

Malware can be one of the many reasons a laptop’s fan is creating grinding noises. The presence of malware can disrupt laptop fans and other functions. Malware is quite harmful to your device.
