A constantly whirring fan on your home computer is never attractive. In most desktops or laptops, it is a sign that your computer has got too much dust in the vents or on the fan itself, or that the cooler is starting to come away from your CPU, potentially causing overheating issues.
You know it’s going to happen, and most likely at a crucial time. It’s there lingering at the back of your mind, leaping forward and causing you panic if there’s even a slight delay in your computer powering up. Yes, if you own a PC, it’s more than likely to have already happened to you: the dreaded crash that stops you in your tracks.
