The reason I am posting this is because I am disappointed with my Zalmon 9500 cooler. I have been doing some research on all 3 of the coolers and have come to a point where I need some help. I would like to stick with air cooling as its cheaper and more in-line with my budget currently. I would like to know if anyone has had experience with any of these coolers or all three. Right now I've got an e6750 and the start up temps run from 35-40c and after 5+ hours of playing games run about 45-47c stock. I plan on over clocking it upwards of 3ghz, and would like the best cooler that can handle this situation. Thanks for all the help
