yup your right Frederic, the Thermalright is prob a better air cooler according to the reviews, I've just kinda standardized and had good results with the zalman. Maybe I'll try one of those Thermalright next. That Aquagate Mini water cooler has got good results as well, but I've read that for a 4 core this is on the edge of being able to drain the heat away from a quad. I do have a galaxy 500 Wc on a q6600 and I've been running in at 3.65 for a least a year although its runs about 60c.
