Without a doubt it could handle it
i dont think anyone is used to working with a water system as massive as the reserators. having working with them, one can cool overclocked 3870 card and 2.2ghz chip upped to 3.0 (amd) fine and dandy, and this is a reserator1 setup.
res 2 has just about 2x the heat capacity.
read my article on water wetter 3-4% and pure steam distilled bottled water vs other things and that huge amount of water in the system will absorb anything you might be concerned about.
9600gt's arent that hot, cpu's make miniscule amounts of heat. I think it would be fine and dandy.
your cpu is choking you!!! dang! isnt that like 5-6 years old? could buy a bottom barrel 775 chips or am2 amd chip and feel like your floating.
has most any zalman part. they are good to ask or call zalmanusa directly.
