If that's directed at me, then I'd like to point out a couple of things.
1, I'm not an expert. I never said I was, and never made any attempt to sound like one.
2, There's a difference between a mild agitation, a gentle prod, a stiff poke, and a violent shake. Which of these you would choose is down to common sense. If you gently touch the blades of a fan and they tilt severly, they are either designed to tilt, (very uncommon I would have thought), or the fan is not quite right. Where exactly was the mention of a fan that runs at particularly high RPMs?
3, the poster suggested it was his PSU fan. I acctually advised the poster not to enter the PSU unless he/she knew exactly what they were ding, and gave good reason. Rather, I suggested that if it is the PSU fan, a replacement PSU would be better.
Personally, I think it's about time that some people on this site started to get down off their high-horses, and start appreciating that nobody knows everything, including theirselves, and to acctually read and think about something someone has said before attacking them. If you had thought about it, you'd have realised that it was a post of suggestions, not advice, and that even then, the first line implied a certain level of general uncertainty for the next suggestion.
I'm not the first person it's happened to recently. No doubt, I won't be the last.
By the way.....
How would they fail? The first thing they do is making a huge noise racket.
you wouldn't by any chnace be confirming my suspicion that the bearings in a fan were wearing out would you?

The weird thing is I use the same power supply on my friends computer when I made it and i makes the same noise
I'm sorry if I'm just being a bit dense here, but are you saying you used a new power supply of the same type in another computer, or that you used the acctual same power supply making the noise now?
