Bigbruin.com has posted a review on the Arctic Cooling Accelero X1 VGA Cooler

I am impressed by the performance of the Arctic Cooling Accelero X1. It outperforms the previous model, the NV Silencer 5, by a few degrees, and cooled the card much better than the default eVGA cooler. The Accelero X1 would be a great choice to keep your graphics card as cool as possible, especially if overclocking.
