Is your TruePower PSU making your case hot? Solution for Antec 800-series and 1000-series cases

I noticed that the Antec TruePower PSU's get a bit warm. I doubt it's a problem for the PSU itself, but since it sits near the top of the case, it's apt to warm up the air up there. And there are no fans drawing air out of the top section of the case.

Is it a problem? Maybe not, but if you want to try something to cool that top section of case where your optical drives probably live, try this:

• Look at the rear of the case where the PSU is bolted in. It's bolted to a plate, which is then bolted to the case itself.
• Of the four bolts holding the PSU to the plate, remove the bottom pair.
• Now remove the four bolts that hold the plate to the case, and flip over the PSU and plate so the bottom fan is now on the top. Bolt it in again.
• Replace the two bolts that hold the PSU to the plate, which are at the top now.

Now the PSU pulls air from the top of the case. The two 80mm exhaust fans next to the CPU should be plenty for keeping the air moving past the CPU. I don't know if this would be a good solution for a 600-series case because 1) there is a lot less room for a topside PSU fan to draw air, and 2) the 600-series cases only have one 80mm exhaust position.

Anyway, I did this with my PPlus880 and everything seems quite satisfactory. I'm still wondering about the 12-volt reading on the PSU, which seems rather low at 11.4V, and this seems to be the trend with the TruePower 330's I'm using to build computers with. What's everyone else getting for 12V readings...?

PP880 w/ True Power 430:
12v - 12.3
5v - 4.9
3v - 3.5

Readings taken w/ Asus Probe, seem pretty constant...
