I know I've tried various other oils and they worked for a few months and then the fan suddenly jammed and wouldn't move anymore as the lubricant started coagulating due to heat.

I think WD-40 is a less than optimal choice overall. It’s about 50% hexane (kerosene, basically), and about 15% mineral oil. The hexane will evaporate eventually leaving only the mineral oil behind. So the next time you need to lube it, maybe look for a decent mineral oil based lubricant. Like the stuff used to keep hair clipper blades lubricated or something.
