Gentle is right. I didn't put any paste on the RAM, just the GPU. I left the included thermal pads on the ram. I checked my wifes temps on her 6800GT earlier, and the core was at 53 degrees with an ambient of 38. During 3D, it would only hit 71-72 at a clock of 430/1100.
The process of putting on the paste is as folows:
1. Clean off the existing paste from the GPU AND Silencer.
2. Apply the new Arctic Silver paste to ONLY the GPU.
3. Reassemble the Silencer to the card. Remember, just a dab.
Hopefully, that should make everything better.
