UberBlue,
yeah, it would be nice to do without unsoldering those... however, there are several large components in the way of the screws that hold them to the heat sinks. So, I am REQUIRED to remove them to change out the sinks.
Krazy,
I don't think I'll short them with a screwdriver... I think I'll check them with a meter through the vent first. If there is significant voltage present on one or both, I will just make sure and isolate that last regulator as that's the ONLY connection either of the "fingers" had.
Again, I am convinced that I messed up with a sliver of solder across two traces or something similar as there was a black soot spot on the casing and the board. I cleaned the area and it was still shorting. So it's fried.
The new PSU has shipped and should be here in a few days. Meanwhile I'm going to start on the HDD water block drive cage. I have some old dead drives around to use as "dummy" drives for the construction so I don't risk my new drives.
