Cool n Quiet creates painful noise

[Promit]

When I enable CnQ on my Athlon64, my computer begins to emit an extremely high pitched noise that is not terribly loud, but is loud enough to be disconcerting and occasionally painful. I'm not sure, but going by ear I'd say that sound is in the 18-20 khz range. It sounds like noise being generated by RF interference, rather than any mechanical part (and I stopped a couple fans to see if the sound went away). If I set my power profile to Minimal Power Management, it starts. Go to Home/Office Desk (thereby disabling CnQ) and the noise promptly vanishes.

Is there any way I could address this without doing anything drastic (e.g. replacing parts) ? I can live without CnQ, but I'd really love to run it; it's just that the noise is quite annoying at times.

System specs:
CPU: AMD Athlon64 3200+, 512KB L2 Cache, Socket 939 (Winchester core 2 GHz, stock cooling)
Motherboard: Asus A8V-E Deluxe VIA K8T890 Chipset Motherboard for AMD Socket 939 CPU
RAM: Kingston ValueRAM Dual Channel Kit 184 Pin 1GB (512MBx2) DDR PC-3200
Video card: CHAINTECH nVIDIA GeForce 6600 Video Card, 128MB 256MB DDR, 128-Bit, DVI/TV-Out, PCI-Express
Case/PSU: CompUSA ATX Tower Case, 400watt Power Supply

I'm not doing any CPU overclocking or anything fancy like that.

Ther RightMark clocking program is a more flexible version of CnQ, where you can set the custom voltage and multiplier.

My guess is that it is the lower voltage that is causing this, so just tell RMClock to underclock but keep the same voltage.

there could be problem in power sulply

Probably has something to do with the voltages changing like slaimus said.

RMClock seems to have sorted things out nicely. So maybe I won't get power use reduced that much without the voltage drop, but at least the heat will probably be less.

Out of curiosity, what tips you guys off to the voltage being related?

[EDIT] Odd, even when I enable voltage changes in RMClock, the high freq noise doesn't appear. What gives?

[EDIT #2] Is it safe to allow a 4x multiplier on a Winchester 3200+?

 

[Promit]

Anybody for the last 2 questions?

 

[Doctorweir]

Hmmm...maybe the noise is from the mainboard cpu power regulator? Making noise if lower voltages are used?

Using RMclock also and runs like a champ...even down to 4x with 1.0V...together with Asus Q-fan saves a lot of noise when not gaming hard

Ok, well the 4x did not cooperate with the 3200+. The CPU simply stopped.

Time to screw with voltage a bit...but I'm still confused why the CnQ driver drops voltage and makes noise, while RMClock drops voltage and no noise results...
