To celebrate its 5th birthday, Scythe has launched a limited quantity all copper Ninja CPU coolers. According to the press release, this full copper version uses  all copper heatsink fins and a slower fan.

The new model uses an improved LGA 775 mounting mechanism that includes a back plate. This was done because of the extra weight that can be attributed to its all copper design. This new cooler measures 110 x 110 x 150mm and weighs 1015g without the fan. The 120mm fan, which produces 40,16CFM of air flow at 10,70 dBA of noise and spins at 800RPM, weighs an additional 115g.

The available quantities of this new cooler are limited due to the nature of the material, so if you want one you should pounce now. It supports Intel's Socket 478, Socket T/(LGA)775 processors and AMD's Socket 754, Socket 939, Socket 940, Socket AM2 processors. The suggested price for the new all copper Ninja is $70.00 and €59.99 without tax.
