I have used Water on other machines, but in a air conditioned room I find fan cooling to be as effective (with a mini desk fan behind the machine to move dead air) I run a 3500+ (2200) at 2695 with a core temp of 40c and case temps of 32c constant.

Antec 80 mm and 120mm 6 fans all together. That video card cooler looks good the only problem is my X850 XT takes up two pci slots and no room for any coolers . IT has a good enough fan it to push out hot air to the rear of my computer. And it runs at 100% all the time. The fan speed that is.

I'm running 5x Zalman f1 80mm fans and the ZALMAN ZM-MFC1 Fan Controller Panel on my rig and love em. They come with a noisless mode that works well it aint p4 system though.
