Neoseeker has published a review of OCZ's Tempest CPU cooler

Now when it comes to the construction and engineering of the OCZ Tempest cooler, attention was paid to almost every detail. The most obvious aspect of the tempest is its 36 stamped aluminum fins. The OCZ label is stands proudly on the side of each, bringing the total surface area of all to 2,300 square centimeters -- roughly. OCZ didn't include this measurement, so I had to calculate this myself. As is expected from a quality product, every fin is highly polish to maximize air flow and reduce the settlement of dust.
