The Thermaltake Volcano 7+ performs magnificently! I am now getting cooler temps than I was getting with the OCZ Dominator 2 with the 60x60x38mm Delta fan on it. The Dom2 with the big delta runs at about 54dBA however and after a few hours it would give me a headache. The Volcano 7+ provides temps rivaling this cooler at a much more comfortable level of noise.
