Yesterday I decided to clean one of my computers, which had a thick layer of dust on every single component inside. I used compressed air, which is a very nice option. However, you must be careful not to point the jet directly at a fan, because it will spin up to extreme speed in no time. That’s why it is a good idea to block the fan from moving, before your compressed air goes anywhere near the fan. I was in a bit of a hurry and slipped with my blocking of the CPU cooler. In a couple of 1/10ths of a second I heard the sound of a fan spinning up from zero rpm to like 20000 and it instantly ripped itself to shreds. There were broken plastic fins everywhere. To assess the damage I decided to remove the heatsink and inspect the cooler. I loosened the fasteners and pulled straight up and BAM. The CPU was ripped out from its socket because the thermal paste had hardened to something resembling epoxy glue. I also bent a couple of CPU pins in the process. Two pretty serious mishaps happened in about one minute. However, I am grateful for the important lessons I learned.
