Thanks all for the help. It turns out that the noise I was hearing was not
from the power supply fans after all. The culprit was the small fan on the
ATI video card. When I put the computer in standby I had assumed the power
supply fan was the only thing left turning, but in fact the video card fan
is left running as well.

I guess the old power supply noise masked the sound of this fan. When I
temporarily disabled the video card fan, I could hear that the power supply
was very quiet indeed. The CPU fan makes quite a bit of noise as well, but
I had identified that sound, which disappears in standby.

Now I need to decide whether the Antec is really worth $70 given the
remaining cacophony.
