squealing motherboard?

[upok]

Oc'd q6600(SLACR), things are stable at 3.2~, 1.36~ vcore(1.31 with vdroop), OCCT stable(30 Min), but when I use OCCT I get a high pitched, barely audible whine, or maybe a squeal?! Is that from overvolting the board? I've heard about whining mosfets, is that what this is?

Board voltages are:

 

fsb 1.4

spp 1.40

mcp 1.5

spp<->mcp 1.4

 

Any help would be appreciated.

 

Oh and it only happens with OCCT, not orthos, or superpi on 4 instances, not during gaming.. I dunno.

Normal with the 680i reference boards.

I don't think mosfets can whine as they are semiconductors. Inductors make the whining sound, and it's almost always inductive coils of copper wire.

My old nForce 2 and my nForce 4 Ultra squealed when heavily loaded and overclocked. My old X850XT did the same thing when loaded down (even at stock speeds).

 

I never worried about it.

So, it's nothing for me to worry about? Just keep on oc'ing?

Good point. Like I said I just saw it in another forum and was trying to isolate to problem. Inductor whine seems to be the most logical solution, thanks.

It is indeed inductor whine... easiest thing to do is dampen it with some hot glue
