Heatsink on eVGA 6800 Ultra

I installed the copper heatsink on the 6800 Ultra using arctive silver 5, and I think I messed up with the depth of the screws on the heatsink. Have any of you guys installed this heatsink and if you have, can you tell me how much of the screw is sticking out of the board? My temps aren't too good. The idle temp has actually increased. Thanks.
 
I installed the copper heatsink on my eVGA 6800 U.

How much AS5 did you use? If you use too much, you can actually cause the temps to rise.

Just screw the HS on until it's snug. Do not over tighten them. Just a little of the screw is sticking out form the bottom.
 
I used a razor blade to scrape a thin layer on the GPU itself. Then I put a little dab on the heatsink and put my finger in a plastic bag and spread it around. I think this was the wrong way to do it, though, because the AS5 instructions are different than the AS3. What I did was for the AS3. I should have just put a dab of AS5 and put the heatsink on. This is what I did on my AMD 64. Check out the instructions here and let me know what you think (I wouldn't have put on AS5 except that someone in my family touched the paste on the new heatsink so I had to put new on). Here's the link:

According to Rivatuner, my GPU temps are 52 for idle and 67 for load. Is this too high? Will the eVGA copper HS do much. Can somebody give me an idea of what I can lower my temps to with this cooler?
 
My temps with the copper heatsink are 49C at idle and 64-67C (used to be 71) at load (like HL2 or that 3d stress program, don't remember name --> rthidbl or something). I think the big thing here is the amount of the AS5 (or whatever you use) you put on. Do not put on too much. Also, check the instructions on how to install the heatsink (screw depth). I forgot to (doh). And there is a burn in period for the AS5 (200 hours) for full effect. Don't use the instructions for the AS3, go to www.arcticsilver.com and use the correct instructions for AS5. All in all, I'm still in the burn in phase and don't really know what I am getting from the heatsink. Still not sure if it was worth the bucks.
