Well I have just tried the Vantec Iceberq and the result was temps about 3-4C higher. Its kinda disappointing because the vantec cooler looks much better than the dfi one. Also, the Iceberq (not iceberq 4 or the spire look alike) needed some alteration to the mounting holes to fit the dfi. Maybe I will try the Iceberq 4 if I can make it out to fry's this weekend.
