this thing is indeed very quiet,
now, i need a quiet case fan: the zalman 92mm doesnt blend in the noise anymore :)
the zalman cpu fan i think 7000AL? on my p4 2.8 is very quiet at low speed, no clicking no noises.

the corsair hx520:
if outside the case, my ear within 1/2 meter i can hear an electronic/high frequency 'hissing', i attribute that to the fan moving. but doesnt bother me in the case, in my desk, it is very very quiet with the zalman 92mm off.

air out the back of the psu is luke-warm towards luke-cool... very nice efficiency

ambient is 27C (NY ... humid)
cpu is 36 idle
hdds 40

interestingly the UPS monitor has decreased in %load at idle, used to be 43%, now is 36%.

will need to do some cpu tester thingy to make sure my p4 wont suck all the 520watts out the psu

The reason why your UPS load percentage has decreased is because most likely, your HX520 is more efficient than your old PSU. This means it can make more computer power from less outlet power. Win-win situation :).

Don't worry, your CPU will not suck 520 watts. I can guarantee that.

what kind of ups are you using? that %load thing sounds interesting.

Active PFC probably also affects to it, UPS might equally well measure apparent power when it comes to such percentage values.
But in case of small ~300W UPS it could really mean realtive Watt loading if old PSU was low efficiency one.

hi

its a 550VA belkin ups with AVR, got it because previous psu had no power correction and where i lived a brownout busted my hdd.

case is bad, bad airflow, i forget the make/model
