Hi there, I recently purchased a Q6600 GO stepping to upgrade my old watercooled 939 system. I still have the hardware Swiftech provided to use on a Socket LGA 775. In the loop I will have an EVGA 8800GT with the MCW60. For the heat exchanger I am using a Weaponized 1971 Bonneville heatercore. The motherboard I purchased is a GIGABYTE GA-P35-DS3L. I am trying to avoid buying a new waterblock so I am wondering If this set up will sufficiently cool this processor. Thanks.
