Yes, it's true, this cooler sounds like a freaking hairdrier. I'm a newbie at this stuff, so this may be a dumb question, but can I replace just the fan and get comparable performance? Or is it just better to get a whole new cooler? If I can replace the fan, which would be a good, relatively quiet, choice? If it should be the whole cooler, which would you guys recommend? AMD 1.2 ghz with an Abit KT7, by the way.
