The Scythe NINJA Copper CPU Cooler one very large cooler! The heatsink weighs in at 1015 grams and if the fan is installed that adds another 115 grams. This is unquestionable heavy but not a big concern because of the way it gets installed using a motherboard back plate. It has an all copper heatsink with many fins. These fins are large and they are connected to long heatpipes which meet into a solid base. Watch the video to find out more and check out the bloopers at the end.
