When you clean your laptop’s fan, you prevent dust from getting into the computer’s internals, leading to more significant issue if not taken care of properly. Debris buildup has been demonstrated to boost cooling efficiency by up to 20% if cleaned regularly.

A small amount of dust builds in the area above the fan and the air vents whenever your laptop is turned on. And if this isn’t addressed, games and movies will run slower, but it may shorten their overall lifespan.
