run up to frys and buy a zalaman fan bracket and a 120mm silverstone fan. Keeps my ram/mosfets/heatsink cooled very well and the silverstone fan comes with a speed contoller....its a 100cfm fan at max and is not very loud.
I was using that fan you linked for a while, its damn good, but when you really want to overclock and need some REAL airflow it doesnt cut it.
