Dust is one of the biggest performance killers for any PC, not to mention the negative consequences for component lifespan due to elevated temperatures. This makes regular cleaning a key part of PC maintenance. Many users recommend deep-cleaning your PC once in six months or a year, but I haven’t done it even once in the three years I’ve spent with my current PC. It’s not that I don’t have the time, or that it won’t help; I just don’t consider it worth the effort. My PC doesn’t have any severe dust deposits, and performance hasn’t dropped either. Besides, regular upkeep has allowed me to delay a deep clean indefinitely.
