I this is biggest CPU cooler fan I ever seen, you can see at the pic beside it a cigarette box and you can imagine how big it. The “Big Boy Turbo Mega Fan 2″ aka CNPS9500 LED, from Zalman is one badass CPU cooler. Drawing a massive 1400W of power, it comes with instructions on how to daisychain five 300W power supplies to feed it and apparently requires “starter cartridges� .
