How can I prevent dust from building up on my PC fans in the first place?
Preventing dust buildup is key to minimizing the need for frequent cleaning. Placing your PC on a desk or elevated surface, rather than on the floor, can significantly reduce the amount of dust it accumulates. Dust tends to settle on the floor, and a PC placed there will act as a magnet for it. Regularly vacuuming or dusting the area around your PC can also help.
Installing dust filters on your PC case intake fans is an effective way to prevent dust from entering in the first place. Clean these filters regularly (every few weeks or months, depending on your environment) to maintain their effectiveness. Positive pressure airflow, where there is more air being pushed into the case than being pulled out, can also help minimize dust entry through unfiltered openings.
