My CPU/heatsinks are causing a very loud and unbeatable vibration. I've been reading and a few hinted at something called mechanical resonation. Though I'm not entirely sure how to fix this.

I don't even want to turn my pc on because of this and am tempted to dish out too much money for a damn water cooling solution.

I've tried adhesive tape and helps a little bit, but not good enough. Only thing that relives it completely is physically putting my hand on it and pushing a bit in some spots.

It's a CM v6 gt and the case is a thermaltake ms-I cmdr snow.

Thanx

It may be a fan out of balance. Or poor bearings. You don't need to go to a water cooling solution just to fix a vibrating fan. If the fan isn't replaceable, simply replace the whole cooler with a different one.

Update- I noticed when I disconnect one of the two fans(doesn't matter which one) the vibration stops....

O.o

You don't have them countering each other, do you? Both are blowing in the same direction, right?

Yes, push/pull- both are facing up

Does the vibration stop when one particular fan is unplugged? Or does the vibration stop when either fan is unplugged?

Either, I can switch em and the they stop the vibrations only if one of the two are unplugged- I keep the one on because it is faving the exhaust vents on the top of the case.

Strange. It is like they are creating turbulence between themselves. Are they matched fans, running at the same RPM? I would try swapping them around and see if that makes any difference. Also, remove them from the cooler and verify that the air is actually moving in the direction of the arrows on the fan housing. They may have been miss-wired at the factory.

They are matched fans- there is no marked direction for them to be facing stangly- I'm trying to RMA them, but I doubt they would let me keep this until a new ine is sent with a deposit or something - I don't really want to have wait two weeks for a CPU fan- but I may have to unfortunaly
