I recently bought and installed an Eisblock Aurora GPX-A water block for my MSI Gaming X Trio 6800 XT. When I benchmark or play a game, the junction temp immediately climbs to 110C and the GPU throttles itself. Core temp is 77-80C. I used the included thermal paste and applied it according to the instructions. When I saw temps were high, I disassembled, cleaned and liberally applied a different brand of thermal paste: Arctic Silver 5 but am still getting max junction temps. I'm using Gelid GP-Extreme thermal pads that are 1.5mm for the front (instructions say use 1mm) and 3mm for the back. All the pads have imprints showing good contact. Idle temps are about 30C. I'm stumped. It's like one of the chips doesn't have a thermal pad on it at all. Can thermal pads be "dead"?
