This has been occuring for a few months now.
The voltage is at 1.3v and I can't go below that in BIOS.
I don't think 2 case fans will make much of a difference, to be honest. I think the culprit lies elsewhere...
Well, the way to problem solve, is to remove all the obvious possible faults, and then you will be left with only the impossible un-obvious. I would be interested to see your case, and hardware configuration.
