Hardware Pacers has posted a review on the Thermaltake Extreme Spirit II Northbridge Cooler

Thermaltake's Extreme Spirit II Northbridge cooler is a finely crafted heatsink (made with 100% copper) with an integrated 40mm blue LED fan. Although larger and bulkier than most chipset coolers, the Extreme Spirit II is definitely worth its weight in style and performance. This cooler's look and feel, with smooth copper frame and stylish blue LED fan, is amazing. With an almost 10 degree Celsius temperature difference, the functionality is remarkable.
