Solid Copper Turbo Fan Heatsink for LED / Peltier

Very high quality, capable of eliminating up to 200 watts of heat from your CPU / Peltier Chip / LED / whatever you throw at it. Large base of 45 * 45 mm. If your target chip is 40*40, the extra padding provides a boost to ensure even cooling. Precision CNC machined, heavy copper block, 88*88mm footprint. Powder coated iron shroud forces air flow from all four sides of the heatsink, to the center, and out the centrifugal fan. Product weight: 374 grams (13.1 oz). That's almost a pound.
