Put a Senfu Water Block on my Radeon 32ddr this afternoon, so far so good. I'm just using the little pump that came with the senfu, the single fan senfu cooler,( without a fan), and have the Pump in a tupperware container, with about 2 pints of water. All this is in my Dorm Fridge, as I run my main Pump for my cpu in a reservoir that I have the freezer section dropped down into, The top of the freezer section gets quite chilly, so for now, I am leeting the senfu rad "absorb" some of the chill from the plate, to help cool the water a bit. Anyone else water cooling a vid card? If so, Please describe how you are doing this , as this is my first attempt at actual Water cooling a vid, and pointers would be helpfull. At present, Room temp is 68f, and the Radeon (LE), is clocked to 169/169, and the temp taken with a probe on the back of the gpu is a flat 75f.
