Opening PSU

Hey guys,

My PSU (Antec TruePower 480) seems to be running really hot, and unable to power my whole system. I had one of my exaust fans die, hasn't replaced it yet. Its the top one close to the PSU. Today I replaced the fan, and I looked at my two PSU fans, and noticed they aren't spinning really quick. If I put my hand there, I can barely feel any movement of air. So, I plugged on of my PSU fan monitors into the Mobo, and it says its blowing at around 1500RPM. I know that isn't that slow, but if I open it up, and pop some new fans in there, will it give my PSU a longer lifetime? Also, are the connections different in the PSU than regular case fans? How would I convert them if I had to? I do have lots of electrical wiring expereince, I am not a Newbie. Also, is there a risk electricuting myself if I open it? How do I discharge it?

Thanks
 
You can usually replace the psu fan with any standard 80mm fan.....the wiring is the same, ecept some have the wires soldered to the circuit boards. Heat IS an issue, just like in any board that has heatsinks on it. Heat is the enemy of electronics.
Also, is there a risk electricuting myself if I open it?

Yea, you could "take a hit"....but someone else will have to help you on discharging it, Im not sure on that one( at the very least, dont touch the capacitors). I dont bother, Im just carefull not to touch the boards, and do my thing.
Just so you know, from the Antek specs:
The acceptable range for hotter, 430+ Watt TruePower PSUs is 1500-3800 rpm. As long as the RPM is within the acceptable range, there should be no problem. This power supply is designed with an advanced temperature response system to run at minimal speed until the temperature rises pass the threshold of 45 Celsius.

Hope this helps.
 
It does a lot, but let me get this straight. On case fans with LEDs which colour wires are which again? I can't rememeber.
 
I'm thinking about doing this too, I want to slow down the fan in my 450watt PSU, its just spinning too fast. It seems to be at full speed, even though it says "Temperature Controlled fan". I was thinking of replacing it or putting a resistor in there to slow it down, but I don't know much about electrical stuff. If someone were to give me exact directions of how to do it, I would do it, and be very careful about working with the insides.
