Sometimes (about 75% of the time), when I power on my computer, one of the fans makes this hideous sound for like 5-7 seconds and then it goes away. I've tried booting with the side panel off to see what was causing it.. But it's so hard to tell with the CPU heatsink/fan combo, NB fan, ABIT OTES fan and the Radeon fan so close to each other.. oh yeah, can't forget the case fan as well.. so what's the best method of narrowing down the problem?
The noise sounds like on of those old Air Conditioning wall units.. best I can describe it
There are no wires touching any of the fans and I've blown them clean
