My limited understanding is that non PFC switchers have very high short-duration current draw that taxes power generation equipment. Electrical utilities don't like switching supplies because they must oversize their generation equipment to meet the high peak power demands yet (billable) energy cons...

However, the reason it is low is due to the work of safety agencies such as UL. You will find that printed wiring boards (pwb) and all plastic parts in PC's ...

After reading thru the responses, I agree that it sounds like a non-grounded PC.

This equipment would generate about 30Vac on the me...

lenny,
I previously saw both your Zalman 7000 mod and another mod that was much more involved. Perhaps I will try it one day, but for now, the noise level is not bothering me. I'll check out the wav files you posted when I get home. My work proxy server has blocked my access to those files!?

I believe the M1A draws 0.4A max. at 12V. Many motherboard fan headers will not supply that much current, and may burn out.
