is a fan controller for my power supply a bad idea?

i have an antec neopower 480 with a 120 mm fan, and it is the loudest thing in my case, not that it is loud, but it is the loudest. so i was thinking of putting a controler on it for when my comuter isn't being used, when it is idling. will i burn up my psu if i turn my fan down? mostly i don't have money for a silent psu, and the neopower is awesome.
 
I'd say it's a bad idea to do that to the fan inside the PSU. What else do you have inside your computer that you can hear the fan on the NeoPower? I can't hear mine at all in my V1100 case.
 

i have a quiet 120mm fan for my exaust and a zalman 7000b-cu for my cpu, and my 80mm fans are at 5v. and are on a switch for at night. my zalman is silent when i turn it down.
 
I've done that to my fan. Shouldn't be a problem. Maybe looking to replace the fan with a quieter one, not just slowing the current one down, would be a good idea. You should be able to get moderate airflow and quietness with a 120mm fan.
 
It depends. Most PSUs these days already contain a thermally regulated fan speed controller. But my Delta's exhaust air was running too warm for my taste (seems a lot of PSU companies are favoring low noise over heat removal these days - a bad idea, IMO), so I replaced its way cheap 2-wire fan with a much better three-wire fan and hooked it up to a mobo fan header. The fan I used doesn't sound too loud at full speed and now I can keep an eye on the second most important fan in my computer.
