Hi! Just bought a visiontek 4850 from Fitseries3, and it's coming this way (thanks Fit). Anywhoo, iv'e read that the stock reference cooler it's crap, and i have a zalman vf-900 unused, anybody had luck installing this cooler on the reference 4850? If so, can you tell me the temps you achieve with this cooler? Or should i buy a newer cooler? The akasa reviewed here looks nice: http://www.techpowerup.com/reviews/Akasa/Vortexx/ Txs!
