"The Nitrogon NT05 is truly an overachiever with an overall dimension small enough to fit inside nearly any case but with performance level surpassing bigger CPU coolers. To accomplish this feat, the NT05’s heatsink is packed with a massive amount of aluminum fins (63) and copper fins (43) to increase its surface area. All fins are also shaped with precisely calculated airflow pattern to maximize heat dissipation." ~SilverStoneTek.com
