I'm not kidding! I've been told how great the Zalman 9700 LED is, and after putting one on my Fiance's computer, I was convinced. So I bought one for my E6600, and the temps are lower than my Thermalright Ultra 120 Extreme! This seriously doesn't seem possible, but I've tried stressing the processor to max, playing games for a couple of hours, etc. and the results speak for themselves... the Zalman is doing a better job of cooling my processor than the Thermalright was... and the Zalman is quieter with its stock fan than the Thermalright was with a far faster fan.
