Lemme just spell it out: I am torn between Arctic Cooling NV4 Rev2 and some passive cooling solution with fans (Tt Giant III or Zalman ZM80D-HP) for my VGA. Which I plan to OC of course. The AC is alot cheaper I must say, but I was thinking that the passive cooling ones might perform better with... say a 120mm fan blowing into it. It takes more work and all that, but the main thing I want is performance. Airflow in my comp is top notch I think at the moment, so I might not even need another fan blowing: 1. 80mm on top. 2. 80mm on side panel. 3. 120mm (about 36CFM) front. 4. 120mm (67CFM, rocket sounding thing) back. 5. modified my PSU to take in a higher CFM 80mm. can't remember spec on that now. I might just get anohter 120mm to blow directly on top of my VGA, if I get the passive cooling one (stuff the 80mm optional fan or 3 CFM 9kRPM crap). I can't get any decent reviews which will tell me which one's better. The AC is winning though, since its got really good reviews, but I think its just because of the brand. Any thoughts appreciated.
