Repair of Thermal Interface Material (TIM)

(1) Northbridge and processor dies, my custom aluminum heat transfer squares, and OEM heatsink plate are cleaned with alcohol and Q-tip swabs. Remember not to touch any of the heat transfer surfaces with your oily fingers after you have finished cleaning! (2) Apply Dow Corning 340 heatsink compound on the dies and carefully place aluminum heat transfer squares on them sandwiching the Dow Corning 340 heatsink compound between the dies and the aluminum squares. (3) Apply Dow Corning 340 heatsink compound to the top of the aluminum squares. Then place heatsink plate over aluminum squares. I gently pressed down, then lifted to make sure everything aligned. (4) Secure heatsink plate to motherboard with screws.
