Weird Noise

post #1 of 7
Thread Starter 
I just OCed my 3000+ Newcastle to 2.4ghz on stock with as5. my temperatures don't get over 45 on load and its stable running prime95 and 3dmarks. But i've noticed that when i hook up my ipod to charge up through usb i get this high pitched wirring coming from the cpu that wasn't there before the oc, at least i think its coming from the cpu.
The noise is only there when the cpu is not stressing, as soon as i run it at full load the noise goes away.
Any ideas on how to fix this?

This is common and I have heard other people compain about it. I have had this happen to me also (on my 3000 Newcastle), It hasnt caused any problems. BTW that is a nice overclock.

The higher pitched sound when idle is the fans spinning faster. When you load up the computer, the components suck more juice from the PSU, starving the fans a bit and causing them to spin a little slower, putting out less noise. When you relieve the load, the power is free'd up and the fans go back to full spin/noise. Best way to fix this is to get a better PSU or a UPS battery so that the power source is clean. I'd say get a new PSU and your problems will be mostly gone. You could also get a fan controller and slow the fans down to relieve the RPM jump/decrease.

There are some good chepones out there Namely a Q-tec 650 watt but ill get flamed for saying that so to be more future proof i would get a OCZ 500 watt or a Tagan modular PSU there very good and stable.

Alright, I figured out the noise is not coming from the fans, i shut them off for a bit and the noise still persisted.
I googled it and came up with something about...cpu throttling...?

Hey!, thats pretty smart. Come to think of it, after I got my new PSU it hasn't happened to me.
