I'm looking into overclocking my FX-6300 and am a bit lost on the CPU Cooler side of it. I've been looking around, and I'm not really sure whether I would like to water or air cool. My maximun budget for a cooler is around $90, and I also have a mid tower, so I wont be able to fit in a large radiator such as the h100i's. Thankyou. Edit: Case- Zalman Z5 (I know. I regret it) Overclock plans: At least to 4.3Ghz
