I will be getting some water cooling this week and plan on cooling my NB. I will be getting parts from frys and microcenter. Mostly DD stuff. I am wondering if I should spend the extra 14 bucks on the DD MPC chipset block ($40) or go with the swiftech MCW30 ($26) I have read reviews saying the DD block is really good due to the new pin design. Would there be much of a difference in performance and/or flow restriction?
