New power supply causes computer to run hot?
The Antec 350 I got yesterday is working, and the fans are running and blowing in the proper direction, but things aren't right. I edited and uploaded one of my webshows today and the processor did it as good as always, but folding is screwed up.
Before the power supply quit, it was folding a frame in THIS work unit about once every 1 munite 20 seconds. Today it was taking 5 minutes, and I just came in and saw it reading 13+ minutes!
Case temps are up 1-2 degrees, CPU is up 5. And that's AFTER I put the CPU back to its stock 1.83 Ghz from 2.20! 2.20 was much hotter.
All this from changing a power supply? I may try deleting and reloading folding in case one of its files got screwed up somehow.

I see, its in a different forum. Dont start duplicate threads.
I can't imagine why changing the power supply would do this. Nothing else got disturbed in the case that I can see.
change the fans in the psu to tornados that should bring temps down 10C
Could it be that since it's not pulling out as much air that more heat stays inside the computer case?
Taking the power supply apart will void its warranty. But I could do it. Does it take standard size fans? Can't the original fans be rewired to get 12 volts full power ALL the time? It would probably have 3 wires going to the fan motor, just cut the extra one so it only gets 12+ and ground?
If that is the case, then definitely.
Does your case have room for more fans? In conjunction with the bottom>>rear path on the PS, AMD also recommends an intake fan at the lower front of the case. This gets cool air coming in the front of the case, passing over the CPU, then exiting through the PS.
Cooling is a topic on which there can be much disagreement, with two seemingly opposing viewpoints both being correct - for their individual circumstances. With all of the variables at play, (case size & design, the size and location of PCI cards, HD's, etc), the only "right" answer is the one that works for your specific configuration. Personally, I've had the best results when using a robust exhaust fan at the rear of the case and an intake fan on the side of the case opposite the MB blowing directly onto the CPU.
The rear exit fan on the power supply definitely does not blow air out anywhere near as hard as the Powmax fan did.
How is your computer running overall? Your current temps of "28 case / 49 cpu" are not terrible by any means. If the computer is stable and those are the temps you're getting with Folding running I'd be inclined to not worry about it. Messing around with the PS thermal regulator will certainly void your warranty. If you get it wrong it could fry the whole computer.
One other thing to consider: When you replaced your old PS you undoubtedly kicked up a lot of dust inside the case. When was the last time you removed your CPU heatsink fan and cleaned everything out thoroughly? I just did mine a month ago and my CPU temp has already risen 3-4 degrees (two hairy dogs in the house...) Try cleaning it out and adding a new layer of thermal paste when you reinstall it. (Get rid of the "chewing gum" heat compound if it's still on there.) If you haven't done all that recently I'd bet you get back something close to the 5 degrees worth of cooling you've lost.
28 and 49 may be okay at 100% folding, but these are my temps at 1.83 Ghz, and I was running 28 and 47 at 2.20 Ghz with the old power supply.
And 27 and 44 when it was at 1.83 Ghz with the old supply.
I sent an email to the tech department at antec.
