OK things are going better with the Expert now.
I put it on the chiller. I have the art of kneaded eraser figured out pretty well now so the board and socket are always perfectly moisture free when I remove the eraser. Even after several days of playing.
After 3 days I noticed moisture on the back side of the board/socket....it's tough to get air in there so I covered the back with Dragon Skin.
Then I realized these old GPU blocks I have are about the same size as the chipset area........so I made a chipset block.
It works great, just as good as one I could have bought for $30-40.
Tomorrow I'm going to put the chipset before the GPU because it gets hot....I think I saw 35C with 1.96v
EDIT: it's held in place with 9-ply nylon waxed lacing cord and it's on there nice and snug.
