If there were mis-contact, it should still run 1-2 minutes from cool before the system shut down by itself (8800 does that, and GTX280 is not hotter than 8800 on idle). Suggest try back the stock fan block to see if they can still operate first.
Yes, but with such a high failure rate I am a bit concerned. Do I need to use the spacer on both sides of the block, I am assuming that only the copper side needs them? In any event the thread on the SLi connectors I used is so short that I could not fit a spacer even on the copper side of the block. What you say about at least getting a signal for a short while is true, that is why I am confused. I will try again when I get the backplates. Any other help/insights would be appreciated such as how tightly I should attach the blocks. My main concern when attaching the block is making sure that the smaller NVIO chip is getting good contact, as I know that this chip runs very hot.
