The guy I talked to at Fry's said that the PSUs might have been designed to handle 13V, but I'm not completely sure I can believe that.
A few things support his argument, though. For starters, there's the consistency in average voltage (12.9V) between PSUs of the same brand. The specs say that the normal operation temperature is 0-40C; HWMonitor says that it's 34C right now. The 12V rail supports up to 60A, by the way. Just sayin'.
The guy at Fry's said it's definitely a GPU driver issue, so I spent literally the entire weekend installing and deleting different versions of my GPU's driver.
I've download and tested the following driver versions for my GPU:
I also looked on NVIDIA's FAQ and checked all 1048 articles; none of them were of any help.
I should also mention that my card was manufactured by EVGA.
The guy at Frys has no Idea what he's talking about.
From the ATX PSU Specs which all
PC Power Supplies are designed to meet
- Tolerance for the motherboard power rails should comply with the values listed in Table 6.
- Table 6. Voltage Tolerances
- Voltage Rail Tolerance
- +5VDC ± 5 %
- -5VDC (if used) ± 10 %
- +12VDC ± 5 %
- -12VDC ± 10 %
- +3.3VDC ± 5 %
- +5VSB ± 5 %

The only way to be sure is check it with a digital voltmeter something every PC tech should have.
The newer GX series Coolermaster PSU's are made by Enhance Electronics and not nearly as reliable as the older units(using the same exact model number by the way) made by Seventeam.
If it happens to be a GX-lite model there made by ATNG and very poor quality.
Fans do not become obsolete.
If the hard drive is still showing a temp of over 42c there's your starting point.
High drive temp could be from lack of air flow, overvoltage, or a failing hard drive.
See if you have a PC Health or Hardware Health page in your bios and check the voltage readings there to start.
