where are the sensors located though? if they read from the molex aswell... then ya.. i'd say they are crappy sensors being used..
and no.. comparing 3 different versions of the same board model isn't "the exact same hardware".. and of coarse you're going to get the same readings when measuring at the molex.. cause it's just the voltage coming from your PS.. it won't change unless you change you're PS..
i'm not trying to start something here.. i actually do want to find out where exactly the board measures it's voltage.. and if it's possible to measure with a multi-meter to double check them..
as for your question Dacs i'd personally say that playing with the power supply is THE last thing you want to do.. sure it's all in good fun and whatnot.. but the risk of screwing up the rest of your hardware.. i think.. is too high...
check this power supply guide by firingsquad done a little while ago.. it has a good table showing you which devices are taking from what rail.. and how much.
