Is dust overheating that desktop?

It turns out excessive dust in your PC can cause more harm that even we thought.  Sudhian.com found that cleaning dust out of a PC cut the CPU temperature down by over 14 degress with the case closed, from 65 degrees before dusting to 50.5 after blasting it with compressed air.  The system was still functioning well at the higher temperature, but likely would have run into problems sooner or later. So if you haven't cracked your case open in a couple of months, you might want to do so before it ends up looking like this fine specimen here.
