Computers get dusty. Inside. No surprise - any box sitting in a dusty corner sucking air through a fan would gather dust over time. Last week, one of my machines took the process to it's logical conclusion.
A few months ago, I took some old parts and built an HTPC. It recorded TV, played DVDs etc. The usual HTPC tasks. The case (and power supply) used in this machine I owned for a better part of a decade. The case I cleaned every time I swapped the guts of the system. Power supply just sat there. Last week the machine started making the usual noises. "Dust in a fan, it will pass" I told myself, as I do every time this happens. Then the machine shut down. I opened it up and sure enough - the processor fan sucked in enough dirt to clog solid. Heatsink was hot enough to fry eggs. Processor was cooked.
I took this event as a sign that it's time to get a proper HTPC case. I was planning to do this for good while anyway. The power supply I decided to keep. It worked well enough for me all these years. Then I had a thought - in my old system, the processor fan sucked air right from the exhaust of the power supply. If processor fan got clogged, power supply must have been a bit dusty. I decided to clean it up before putting it into a new case. Most of the dust fell out as I was opening the PSU. These are the lefovers...
