I've usually been able to find at least one monitoring program that gives fairly accurate readings, but I once had an ECS K7VTA3 ver. 8 mobo that didn't work with anything. SpeedFan said the +12V rail alternated between 6V and 8V, 1-2 times a second, while MBMx read a steady 10.62V, which I had earlier confirmed wouldn't let the very same hard drive spin. A multimeter read 12.11V.

I like MBM5 because you can edit a configuration file to tune the scale factors to your particular motherboard. It also allows you to use your own names for voltages, fans, and temperatures, plus many other settings. Do any of the current hardware monitor programs have such features? - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
