Any body know how to adjust the PSU fan speed, mine reads only 842 RPM, and i think that this may be contributing to my cpu temps benig a little higher that expected. I have a AMD 6400+ with zalman 9500 and arctic silver 5 paste and my cpu temps are still reading about 36-40 C idle.

Unless your PSU came with some way to change it (and AFAIK most don't) then you won't be able to change it. But most PSU's either have the fan set to top speed, or are thermal controlled.

And I'd recommend against opening up your PSU to do any work on it.

Anyway, the RPM's may be reporting wrong anyway.

LOL !! yeah not everyone here lives in US.
Anyway, i really dont like to do anything with the PSU. Just keep it and if you really feel that you arent comfortable with it then just wait till the warranty period finishes. Next you can open it and change the fan without voiding your warranty.

I recently changed my fan of my generic power supply unit and it went without a hitch. I made an article about the procedure: How I Changed the 80mm Exhaust Fan of my PC's Power Supply Unit (PSU). It's by no means an authoritative guide and I don't recommend anyone following it (disclaimer, disclaimer) but maybe some of you might want to see how easy it is. PLEASE READ THE ARTICLE'S DISCLAIMER BEFORE DOING ANYTHING. :P
