Overheating PSU?

Not sure how else to qualify this, but I'm pretty sure my PSU is overheating.

First and foremost, the desk I use incorporates a rather small slot to place the computer (while I have done as much as I can to improve the circulation, the place is still small and heat tends to build up on it.) Up until recently, I had a fairly poor case, cooling wise, so I decided to upgrade since I was experiencing some overheating problems.

After moving to the case I did notice that the rest of the system remained remarkably cooler (the case was a Lian-Li with a 25cm fan) and it was remarkably quieter to boot (larger fans and all). That was until I moved the case into my desk, which caused a fan in the system to spin feverishly which created a fairly loud noise. After eliminating issues, I've reached the conclusion that it was my PSU (not only being the smallest fan in the case, shortly after crashes, my PSU remained almost too hot to touch.) These crashes are instances where the computer just freezes and eventually reboots without a BSOD.

In the past I've thought I had issues with my PSU, but at the recomendations of the people on these forums (I did some testing with a voltage reader), those concerns were dismissed. (I honestly can't recall the exact numbers right now, but the 3 and 5v were good, but the 12 was high, but not too bad).

My specs are as follows:
Asus nForce 570 SLi mobo
8800 GTX
AMD 6000+
2 HD (one seagate (IDE), one WD (SATA))
SATA DvD burner.
4GB Ram.


My PSU is a PC P&C 750 Silencer Quadro.

Could my PSU be overheating? Is this a potential cause for my issues? Silence is a key part of my computer (I do watch a lot of movies and tv shows on it), and having a loud fan on a PSU is a large inhibitor (besides the random crashes).
 
It could conceivably be overheating. Have you tried keeping your system outside your desk and reproducing the conditions under which you were having your issues? If everything is fine outside of your desk, then it would seem that it is the issue.
 
I have placed my case outside my desk, which causes it run fine. Which basically confirms that something is overheating.

Is there anything I can do combat an overheating PSU, besides trying to buy a cooler one?

Aside from that, you can improve your cooling, or you can decrease the power usage of your computer by changing components, removing overclocks, etc. That's basically it.
 
Mount another equal sized fan over the psu fan. Thats what i do, and it keeps my pc working in my 99F room during the summer.
 
When did you last check the voltages using a multi-meter? According to your last thread here in the PSU subforum, you thought you had PSU problems around June of 2008.

Just out of curiosity, have you done any sort of stress test (CPU, GPU, HDD), once while the case is outside and once when the case is inside?
