I was having a play with speedfan (motherboard monitor) the other day noticed my -12v reading was -0.97v. My -5v is -2.04v. The computer has been setup like this for years so I wasnt too bothered, although it is not what I expect! I expect -12 and -5v !! Can the -12v and -5v go down if the PSU is under heavy load? Ive checked speedfan on another computer and it is taking similar readings on that one too. So I tried MBProbe and this gives normal readings on "this" computer but the same as speedfan on "my" computer. Ignoring an issue with MathCAD which took a good few months to identify my computer has been solid as a rock. Surely id have problems if these were the proper readings?
