Squealing q6600

So i finally got my water cooling setup for my q6600 so i can start overclocking, i noticed that under load at about 1.3v i can hear a squealing/squeaking sound coming from my cpu. Is that normal... or if not normal does anyone else have this problem?
 
Oil it, just kidding ..

Its not the cpu (well its possible but I have never heard of it) its the inductiors or a capacitor in the cpu voltage requlation circuity around the cpu socket or one of the decoupling caps direclty under the cpu socket in the "well" in the middle. I guess it could be one of the caps on the back side of the cpu too.

Think of the squeal sound a charging camera flash makes, your sound is caused by the same thing, a high frequency vibration caused by the changing electric field of an AC voltage.

What has happened is the higher current draw and higher voltage setting for the quad core has increased the strength of the electic field and made the vibration strong enough to hear.

What is difficult to say is if this is a problem or not, I could be from increased ripple in the incoming voltage due to your cpu voltage requlation circuity becoming overloaded (unlikley unless something is failing or the board was not orignially designed for a quad core) or just a side effect from the increased current. Inductiors often squeal due to loose windings or ferrite cores. If you notice a lot of power supplies have "gunk" around the base of some caps and inductors. This "gunk" is there to dampen the vibrations and reduce or eliminate squeal due to high currents which are normal for power supplies.

So the squealing is kinda "normal" under high current situations but on the other hand it could indicate a failing component. No way to tell without putting an O-scope on the power traces and seeing how "clean" the voltage going to the cpu is.

What board do you have ?

edit:
But if I had to guess I would guess its more an annoyance than something failing. Try taking an wooden probe and pressing on the caps and inductors aournd the cpu socket and see if the sound changes to try to identify exactly what is making the sound. If you can find the component sometimes a "blanket" of hot melt glue ("gunk") will stop the sound.
 
thanks for the timely response, i guess im not the only one up at this hour. My board is a striker 2 formula, i have another one on the way for a lan rig and ill try it out and see if it makes the same noise.I will have to try that first thing tomorrow. thanks for the info and the tips
 
For the record, it could be your PSU as well. It's more common for a PSU to have this issue than a CPU voltage regulation inductor, so it's possible the sound is actually coming from the PSU and you just thought it was the CPU area.
 
I thought it might be the psu, but i ran my pc with it ouside the case and it still sounded like it was coming from the cpu or somewhere very close to it, thanks for the suggestion though
 
Definitely sounds to me like a PWM going bad, try turning everything back to stock and see if that helps.
 
so today i got really bored. what i did was made little "noise isolators" out of some old styrofoam coolers i had laying around, and turns out the sound was coming from my psu. later i might take the psu apart and prod around with a small piece of wood to see if i can locate the sound. thanks everyone for the help and suggestions. Edit:: can anyone recommend a really quiet psu:)
