One of the most common reasons that laptop fans suffer from sound pollution is that they might not have been cleaned in a very long time.
Dust accumulation or misplaced components can cause the fan to not work properly and grind unnaturally. All the same, ensure to check if your computer fan is working properly.
If you want to keep your laptop fan as highly functional as possible, clean them at least twice a year. The steps you need to follow to clean your laptop fan are given below:
