Recently one of the more interesting product released in their VGA cooler line-up is the all new Accelero XTREME 4780X2 cooler. It is a massive eight heatpipe based cooler that might be as big as a whale, yet is virtually silent and has extraordinary cooling performance.
If you are gutsy enough to strip down the X2 and mount a this cooler, then you can achieve temperatures that are roughly 30 degrees C lower than I've just mentioned, right out of the box.
