Interesting, as with my 550watt the power rail origin was the same point, so the bridging it would not have made any difference.
I notice that you have a copper "Cover" near that coil in mine that gets hot. Is it in contact with the coil?, I was intending to do something similar but wasn't sure if it might short something.
It can be seen in this image, it's the coil shown by the shorter Pink arrow, (click for large image).
If this is possible I could easily run a copper plate to it from the side of the waterblock shown here.
