Antec TruePower PSU raised my temps

[idea]

My old temp, with a OEM PSU in my Aopen case:

46 idle, 55 load

new temps:

52 idle, 57 load

I mean I know this PSU is supposed to run quieter, and it does I think... but I figured having dual fans would help suck the air off the CPU a bit. I admit I don't have the best cooling setup, 57 is probably expected, but even so how did it raise even if I added an exhaust fan (the one in the psu)? I don't recommend using this PSU as means to cool off your system if you're overclocking, you'll definitely need another exhaust fan in the back.

yes the powersupply does get pretty warm I have one. but just install a good intake and exhaust and use those fan headers that it comes with it has a thermostat in the powersupply that will slow down the fans when not hot inside and go to full speed when it needs it

It sounds like the PSU is the only exhaust in your case, if your temps are rising that significantly... am I right? Add an auxiliary rear exhuast fan such as a Panaflo L1A 80mm fan (if you're a newegg shopper, be warned: they sell an 80mm L1A but it's a 24-volt fan, don't want that ).

I recommend not using the fan headers. They don't put enough voltage to fans to do an adequate job of cooling. I've never had my temps up enough that the fans would spin up higher, despite my tbird hitting 65C!

The thermal trigger for the PSU is set just too high. After a little while, you can feel hot air coming out of the exhaust yet the fan is barely spinning. Your comp will need to be on fire before the fan will spin up. That's reason why this PSU is so quiet. Another problem I had with it was that the voltage rails would drop to unacceptable levels (430W model). I don't know why people praise this PSU so much.

The voltages aren't suppossed to drop (that Voltage Feedback feature) that much. It also depends on how you're measuring it (ie MBM5/BIOS is not the best way to measure voltages).

BIOS is not the best way to measure voltages

So you're saying that the voltages reported in the BIOS on every computer is incorrect?!

It certainly can be. Get a voltmeter from Radio Shack and check the BIOS voltages against the real voltages as measured by the voltmeter. You might be surprised. On my A7N266-VM, a very good-quality board, the BIOS reported 11.4V on the 12V rail. Guess what...

If I leave my case open, it drops 14c. I think that's enough evidence that another exhaust fan'll do the trick. For now my case will be open. The rails are fine, I'm actually getting a little too much juice.
