Cooler KX heatsinks are offered in several grades of finish and include mounting hardware. The Simply Better Manufacturing website offers guidance on which model to choose. Illustrated step-by-step instructions are provided to make installation quick and easy; no messy thermal grease application or tedious paint removal are necessary. Price: $79.50 to $118.
