SpeedFan voltage accuracy?

[lcaley]

Hey guys, I hope this is the right section for this. I installed SpeedFan just for the fun of it earlier, and it's reporting that my +12V rail is at 9.87V. Is this normal/acceptable or should I worry? Or is this just another thing thats not so accurate. It also says that my system is at -65C, and I'm almost positive that's not true :lol:.

My PSU is a Thermaltake Purepower 600W on an EVGA 680i mobo.

Thanks guys, let me know if you need more info.

speedfan isn't always too accurate, and on vista64, who knows, could be even worse.

Try HWMonitor. It is made by the same guys from CPU-Z.

Thanks for the reply. HWMonitor shows my +12V at 10.43. That's closer, but its still not 12. Of course this one also shows my system at -64C lol... I also suspect Vista64, but I just thought I'd see what everyone else thought.

unless your motherboard came with monitoring software (mine came with PC probe) then anything else might not work. You could TRY to find 64bit versions of these programs. Your temp sensors could just be off too, and it's always possible the PSU is slightly undervolting.

I'm sure my PSU isn't perfect, but at what point should I start worrying? Is 9.8/10.4 (which ever is closer to correct) acceptable?

I looked through the disc that came with my motherboard and there wasn't really anything on there except nTune.
