Great product, I had been contemplating buying this for a while, and im glad I finally did. It lowered my 8800GTX from 65c idle and 80c+ under load, to 50c idle with 58-60c under load, with an ambient temp of 75f. I have it on a loop with a core 2 duo 6600 with a MCR220 radiator. You do need at lest a dual 120mm radiator, due to the high heat out put of the 8800GTX. Other then that I highly recommend it, great product, and glad I bought it.
