FSP350-60GLN PSU started peeping after replacing Asus P5W DH with P5Kmotherboard.

[D]

Hello!
FSP350-60GLN PSU started peeping after replacing Asus P5W DH DELUXE
with Asus P5K motherboard. Asus probe 2 and Everest show, that the
voltages are fine all the time. How to prevent the peep?
Best regards,
Dima

Thanks kony for your suggestions!
The noise comes from the magnetics (transformer or inductors). It
continues even after shutting down Windows sometimes.

Thanks peter for replying!
I meant a whining or creaking by the peeping.
Why does www.silentpcreview.com write "most powerful Intel 670
(P4-3.8) processor rig with nVidia 6800GT video card drew ~214W DC
from the power supply under full load" on http://www.silentpcreview.com/article292-page4.html
for example?

My PSU uses Protechnic, not Yate Loon fan.

Peep, not beep. The main transformer or an output choke may peep if
the load is just right, usually on the high side.

Thanks do_not_spam...@my-deja.com for replying!
I replaced FSP350-60GLN PSU with Zalman ZM460B-ASP. The Zalman is much
quieter!

Yes, I determined the peeping is coming from the electric circuit, not
from the fan.
The fan makes a different noise from its vibration.
I replaced the FSP350-60GLN with ZALMAN ZM460B-ASP. The Zalman is much
quieter.
