just out of morbid curiosity, why would you spend almost 200 bucks on an aftermarket cooler? what exactly was wrong with the one that came with it? even FE cards can do the job. I dont understand why you would spend that much to AIR cool it?
unless you're experiencing severe performance issues due to thermal throttling, you're better off investing in ways to get a positive airflow in your computer case than slapping on a cooler that won't help that much (maybe 5% performance increase if you bump up clocks a tiny bit).
Anyway, just make sure the 'be quiet silent wings 3 120mm' is high static pressure.
