>> Asus EN9600GT Silent Video Card Review
The worst thing about the exclusive V-cool heatsink (really the only bad thing) is that to get enough surface area for the passive cooling to be effective the normally single slot 9600GT becomes a dual slot design. I also found that the back edge of the passive heatsink blocked the retention clip for the six-pin power connector the card requires. I had to lift gently on the fins of the heatsink to get the clearance needed for seating the power plug.
