Normally I run my 5770 Hawk at 1000MHz core clock, 1200mV core voltage and 1400MHz mem clocks, and manage keep the temps below 70C and the fan below 50%.
Today I changed my CPU heatsink, and now my GPU even at stock clocks (875MHz core, 1125mV, 12000MHz mem) jumps to over 80C near instantly, and the fan has to run at 00% to stop it getting well into the 90's, although the fan speed seems to have very little effect, a 50% fan speed only seems to make like 1C difference...its as if the heat just isnt getting from the core to the heatsink suddenly...
When I first saw this I litterally thought one of the 2 fans must have died or somthing, so open up my case again, but both fans are working, and moving a lot of rather cold air around that heatsink... Even the other side of the card near the CPU is getting a lot of cool air pulled across it due to the rear and top fans on my antec 300....
Any ideas on what I could have possibly done to it and what I can do about it?
