HELP! Antec Sonata PSU problem

Hi!

A new Sonata based system landed on my doorstep today. Typing away on it right now.

Problem: The PSU fan is not moving at all and I have been running the system for more than an hour. Is this normal? Shouldn't the fan be spinning at least a little?

I do not want this system to burn up as I install BF2, what should I do?

Thx,
mattek

assuming that you mean the Sonata II is your new case, you dont have a problem. The new Sonata II's feature the Antec SmartPower II power supply. The new Power Supplies have two 80mm the exterior of which (the one you can see) only starts spinning once the temperature gets high enough. Read the SPCR review for more details http://www.silentpcreview.com/article260-page1.html

Ahhh.. Didn't know that. Thanks.

Can this threshold temp be configured somehow?

Thx,

not from the outside. If you cracked open the psu and figured out how the measured the temperature im sure you could figure it out somehow.

About a month ago I bought a PSU that had a stuck fan in it. Plugged the PSU into my PSU tester and the fan didn't spin at all. Gave it a good push with a screwdriver and it started spinning (wish it hadn't now, the thing is noisy and will be replaced). This probably isn't the problem you have, just an FYI.

Leave it on a torture test in Prime95 for a few hours and then see how warm it's gotten to touch, if it burns you you've got issues, if it's not then be happy, your PSU is silent.
