got my 64 bit 3500 (venice) today will be putting it in with everything later. The Zalman 7700 is one heavy MTF lol. But i think the way the mount it will be perfect. Uses a backplate and just screws onto the board basically. Ok now for my question. The Zalman 7700 came with a small tube of its own thermal paste (Zalman brand) now im wondering if i should use this or go buy some artic silver.. Like i said this thing requires you remove the mobo to mess with it so i want to do it the best way i can. On the tube it says Zalman thermal grease (CSL 850) What you guys think?
