| I guess yesterday's post is gone (I was formarly MK). I did some testing of the power supply voltage with a Digital Voltmeter and compared them to MBM 5.04 readings. They were not the same. The voltmeter showed +5V Supply to be rock solid at about +5.18V while MBM displayed +4.88V to +4.98V. Similarly the +12V Supply read a solid +12.33V while MBM varied between +11.37V and +11.8V (I'm trying to remember the values I wrote yesterday, may be slightly different). Does anyone know how MBM determines the voltages? I trust the voltmeter and wondered why the discrepancy. I think that the Temps and Fan RPMs are correct. |

| i'd trust the multimeter to.my 12+ reads 11.1 to 11.4 but i haven't threw my multimeter on it yet but suspect i'll find the same thing as you.as for fan rpm the value isn't as important as changes in speed are.for example if you notice your rpm slowly looseing rpm over time it may be time to clean.as far as temp accuracy i believe theres away to fine tune temp with mbm but i cant find it right now.maybe start another post just under that subject and someone will reply.
