Lately, in an effort to get the best bang for the buck in my new system to be, I have been researching effective cpu coolers orther than Zalman, as I feel they are too expensive, and I can get a better deal. Anyway, my cooler will be used on a PD 805 overclocking to between 3.4ghz and 3.6 ghz. So, I've narrowed it down to two coolers, the Artic cooling Freexer 7 Pro or the Scythe Katana. So, which one should I get? And is their something better around the same price range that I'm missing?
