Well................ I use eraser. Lots of it.
Eraser the whole back of the board. Liquid tape around anything that doesn't have eraser around the socket. Also eraser around the socket leaving a gutter before the ram so I can roll up a paper towel and shove it in the gutter which prevents the ram from freezing. A layer of paper towel before a 1" thick pre-cut neoprene dealio. Then some magic sauce, aka OCZ Freeze, and pot it. Also stuff paper towels anywhere that condensation can build up. Fans on the NB, Fets and Ram are also a must. Have the A/C, which is 4' away, blasting cold air over the rig. My setups isn't as pretty or as perfect as others but it gets the job done.
Hope that helps buddy.
