It's a recording of my computer. It seems to make this noise when I start it up, and continues to do so for about 5-15 minutes after I'm on it and everything, then it stops and everything's fine.
Any ideas?

Yeah this happened to my Akasa fan nebula (although it was manifest in noticably slower spinning and a more noticable vibration in the case). I took off the stick, opened up the rubber cap and drowned it in WD40.
Job done.

I have NEVER known this to happen, even on cheap fans. Your original post said that over tome the fan blades lengthen and then when cold they touch the fan surround. But then the fan surround heats up and enlargens meaning that it doesn't anymore.
Firstly, plastic has to heat up an awful lot more than that. Secondly IF you did manage to heat it that much, then the fan surround would also expand in the way, so the noise would continue.

I have indeed tried that numerous times before, and it's worked.
Doesn't work with this though.

It's true! It does happen! The gap between the fan blades and the casing decreases as the fan is used more. Tends to only happen on cheaper fans. Sometimes the bearings can play up as well. Try hitting the case - see if that stops it.

However I seriously doubt it's this.

I think it could well be your PSU fan.
I had opened it up a few days ago to see if any wires were touching fans or anything, so it's not that.
However, I had a listen as to where it's coming from, and I do believe it's coming from the PSU.
Which, in an odd way, is a good thing I suppose as I'm looking to get a new PSU anyway.
It's a reasonably oldish one, so you think that's probably it?
