Weird Sound from Motherboard, near CPU?


May 19, 2012
Hey everyone, I'm hoping this is the right section to ask my question.

Basically, I just bought a new PC (I built it myself):
i5 2500k (running with stock cooler just for now)
ASUS p8z68v
corsair vengeance 8gb of ram 1600 mhz
gtx 285
ULTRA 650W psu

i'd also like to mention i heard a weird sound around the CPU area.. it was a bit high pitched, but when i run Prime 95 stress test, the sound went away... as soon as i stopped it, it came back... should i be worried? is the motherboard or cpu defective?

anyways, i'm getting around 67-66-69-68 currently after 25 minutes... are these temps normal with stock cooler?? thanks!
I hear the same thing from my P8Z68-V LE. I THINK it's from the VRM's, but I never have figured it out. It seems to be a common thing on Asus boards though, so I just don't worry about it, and it's not THAT annoying anyway (I can only hear it with my ear literally right up next to the mobo).

As far as temps go, they're fine for the stock cooler. Just as a comparison though, I have a little less than that (low to upper-mid 60's, depending on room temp) @ 4.5Ghz and 1.277V in Prime, with a Hyper 212 Evo.

That seems to support my theory that it's the VRM's. Turning the power states off, along with SpeedStep, takes a lot of stress off of the VRM's.

I just say don't worry about it, unless you have REALLY sensitive ears and can't stand it. It's not hurting anything.

It's not unless every person that has this problem on an Asus mobo has a bad HSF installation (very improbable)...
