I vacuumed and cotton swabbed the cases and innards of 2 PCs last night. One of them had hung, forcing a reboot, earlier in the day. It had a lot of crap plugging ventilation holes, in heat sinks, and on fan blades. That one might not have been cleaned for too long. Perhaps. Maybe. It could be.

Its cores are running up to 15C cooler with, right now, Firefox, a turn-based Steam game, and a video stream running. The ambient air temperature is about the same.

The other PC is the mastodon server and it was almost completely clean inside.

A tale of 2 PCs.

Clean your PCs!!
