I've heard good things about the Accelero Rev. 2. Although, without a fan on it, it'll just be passive cooling and would rely a bit more on your airflow, which could be good or bad depending on your case. Either way, though, passive cooling results with it on the 4850 have been shown to be very very good.
tested with Accelero rev.2, Auras Fridge and HR-03 GT all manage to coll 4850 very good with a slow\silent fan
