Strage voltage readings with speedfan

[edm]

I've been having some problems with my computer recently (mostly when gaming) with Artifacts, freezing, etc..

I figured the problem was the video card because it's been over heating with the gpu fan reaching 100% occasionally. Temps have been hovering around 85c. Peaking at 90c under load. Other times however, it's stays below 60c when playing the same game. Sometimes I idle at 40c. Other times it idles at 60c. Which seems odd.

I was told to check the +12v reading in bios, which show a normal level at +12.09.

However, when I checked the readings using speedfan it shows two +12v readings. One is normal but the other is above 16v! Obviously that's too high!

So how trustworthy are speedfan readings? Should I replace my power supply?

Specs (I know its ancient. Please no judgement My plan is to upgrade everything this fall.)

GTX 260
Phenom II X4 940 Black Edition
ASUS M4N82 Deluxe mobo
8 Gig ram (4x2)
Corsair CMPSU-650TX 650-Watt
Antec 900 case
Win10 home 64 bit

Air flow in the case is good and everything was air blown for dust about a month ago.
If you need any more info please let me know.

I would look for another way to access the situation.

As seen above -

-12V is -1.42V

5V is 1.83V

temp3 is -128C

Yeah. The numbers on the far right are the ones I'm seeing in bios. Not sure why the other ones are so out of whack,

As for the -128C. I had done a google search and apparently there's a bug with speedfan that tries to read a sensor that doesn't exist, and gives a false high or low reading on temp3.

Does anyone know of another program that would show the voltages?

Download and use the Portable.

Thanks for the link. I ran both hwinfo64 and hwmonitor. Both are close to what I get in bios. With the +12v, +5v, and +3.3v all within acceptable ranges. hwinfo64 does show two readings for the +3.3v however? And neither have all of the readings shown in speedfan however. Maybe they don't exists, hence why the readings are so out of whack in speedfan?

Speedfan is ancient. I believe I stopped using it sometime around 2006 or 2007, when some of its features seemed to stop working.
