12v dipping to 11.78v ...

post #1 of 6
Thread Starter 

Alright, I was just testing this, and when I put some sort of load on the PSU, the 12v drops, it's 11.97 at idle, but this is the lowest I've seen it go, wonder what happens if I put full load from everything in my system..Is Speedfan just inaccurate? My temp readings are pretty off too, but the 3.3v and 5v seem to be fine, does anyone know any other programs that measures voltages accurately?

I don't trust any software voltage monitor, none of them have ever given readings as accurate as a multimeter.

Even if those readings are spot-on they're not so low as to warrant any concern. 3-5% fluctuation is acceptable.

The thing is that the program reads directly off the I/O chip which checks the voltage, so it wouldn't matter changing programs.

Besides, SpeedFan is the most customizable and thinnest program of anything related to monitoring temps and voltages.

For OCers a 3% variable is prefered but up to a 5% variable is acceptable.
