Right now my rig has an E2180 in it overclocked to 1600 FSB and runs great but I built my rig intending for a 45nm quad core beast so I'll be finally buying a Q9650 here in the next two months or so and I do plan to OC it up to the 1600 for that 1:1 ratio. But lately I have been contemplating water cooling along with this CPU swap. My rig puts some noticeable heat which I hope to reduce and just keep my system at a generally cooler temperature. Right now I use a Zalman CNPS9700 cooler which rocks, but with respect to CPU cooling alone (water cooling has to implemented in the whole system right?) what kind of temperature changes can I expect?
