large amounts of condensation, you will need to seal the peltier, the area around the cpu on the motherboard, the area underneath the cpu on the motherboard (socket 370 board), the on die cache on the bottom side of the cpu, and the space between the closed cell foam and the heatsink, with electric grade silicone. I recommend getting a peltier kit since it comes with the cold plate and closed cell foam needed with a peltier. Also, the PEP66 has 4 rubber feet on the bottom which prevents it from touching the peltier completely, which will cause the peltier to burn up. You will need to cut off the feet with a razor, or you could get the PAL6035 from alpha, which does not have the rubber feet, and cools peltiers more sufficiantly. The fans, the peltier kits, and the electric grade silicone can be purchased from
