This is my Gigabyte GTX 460 1GB under stock Voltage of 975mV,
the memory will go a little higher but the core clock won't, even if i go up to 1.081V. I've already reapplied the thermal paste on the card.

Under full load via F@H. My top card is dying. Very close to breaking 100C w/ the top card. The cooling on the Zotac 1GB cards is rather poor. I need to buy waterblocks for these bad boys asap. My Gigabyte GTX460 768MB card will do the same clock easily enough as well. I just don't have room for the card until my motherboard gets back from RMA.

I don't know why but even in reviews Zotac 1gb card was the hotest. The EE heatsink used by Evga and Zotac is worst than reference. And you have a problem with fans , you must flash a new bios to unlock them to 100%.
Two Gigabyte cards should have been a little better.

The problem for you most likely is the IHS itself. Do some research and pop that sucker off. From what I can tell the IHS will come off a'la A64 style, carefully use a razor around all sides, and dont let the blade go further in than about 3mm.
