my pc roars
 

i put off the case, made it all dustfree but still it roars.
I can hear the roaring is not coming from a fan, but from, i think it are cooling ribs (like on a cilinder of an engine), behind a fan. When i stop the fan for a while with a pen the roar is still there.. what is this? How can i fix this?

i have the same problem with one of my pc's doesn't really bother me. could be a bad fan or power supply. i actually feel naked when I turn it off

get a new fan decent one ball bearing n all or watercool if you wanna...

and dont stop that fan too long or youll get a fried processor...

just kick it !

Fanless cooling.

If it's still there when you stop the fan, then it's not that particular fan. I assume you are talking about the processor fan, so try stopping the power supply fan at the same time.

I'd guess it's the power supply fan and it's vibrating the power unit, and that in turn is causing vibration somewhere on the case (doesn't even have to be near the power supply). The cases are made so thin these days that audible vibration is a common problem.

Pinpoint where it's coming from and pack some foam or cloth in if you can. I put some between the metal top and the plastic outer shell and it took care of a very high pitched vibrating on mine.

yea, i think its something thats against or between those ribs whats causing it.. when the fan in front of it is spinning very fast, the roaring is gone, the slower the fan spins the harder the roar gets.. ill look into it once im done working.

...and it was exactly like this... so simple!
it seemed that the screws of the monitor plug were vibrating because they werent screwed tight, i just moved and probably forgot to put em in better.
Caused a hell of a noise! Just screwed them in better and the noise is gone..
thanks for the heads up :pimp :pimp

Mine was roaring the past days and I think it's on the fan.. Got problems with my power supply two weeks ago and that has something to do with this..
