Hmmm, good find!
I have seen this on EVGA 780i with the SB HS connected to the others with a flat wide slab of metal but the 680i uses a pipe ... since finding this, I always check the temp and if it seems high, I re-do the whole thing (not an easy DIY)
Well, let us know how things go after you get them.
Remember, build the motherboard outside of the case, as in, install the CPU HSF and RAM before putting the mobo in the case, you can even attempt POST with the board out first to ensure everything is working.
