The joys of hardware
I've been hearing an odd sound in the office the last couple of days. At first I thought it was the scanner, but it continued to persist after the scanner had been turned off.

This morning, Jacinta remarked that she could distinctly smell the odour of frying silicon. That filled me with dread, having already had two power supplies and a hard-drive die in our main server over the last few years.

It ended up the problem was a CPU fan that was on the verge of dying. The smell was caused by dust that had burnt on the heat-sink after the fan had stopped working. An easy enough job of swapping in a new CPU/fan. The old CPU works, but I don't have a replacement fan for it, and don't really have a use for it otherwise.
