rad needs unobstructed airflow to maximize efficiency, might be time to look at another cpu block, koolance or heatkillers.
Thanks, the rad rests on 4 legs about 3 inches high so its not laying on the case top......it was only like that when I was setting it up and testing it out. The air blows straight down and through the rad..........I didnt think it could be the waterblock! Hmm something with more mass to it? I idle at 27-30c.....its only after 20-30 minutes that the heat seems to overwhelm the cooling system. Seems like its not drawing heat away fast enough so it builds up over time with te Thuban where as the Deneb rose to a certain point then couldnt deal with the cooling and level out at 50-52c. This is at 1.575v.
