nev_neo, I wouldnt want to avert any heat of the core away from going directly to the heatpipes. I dont think one could improve on the two heatpipes that the heat from the core goes directly into, so I think leaving it as it is is fine.
ZX81, yah, that's more along the lines of where you should be
. Personally, I'd open it up again and put more on the GPU core, 96C is still damn hot, hell, you can almost boil water at those temps. I bet that if you take the heatsink off the card, you'll notice that the core isn't making complete contact with the heatsink. Unfortunately you need a good amount more than just a thin layer for these cards
Don, neither of those games are very GPU intensive. As stated, ATiTool and FEAR are probably two of the best apps to get the temps up. Here's the link to the sample pack
from onlinemetals.com. I think the 16 oz. would work well in this case.
