Pumping an impressive 25 cubic metres of air per second Zalman are confident that the 'Big Boy Turbo Mega Fan 2' will be able to keep any Intel CPU, up to and including the Pentium 4 670 3.8GHz, running cool in even the warmest conditions.
Developed with the help of the British Aerospace wind tunnel engineers, the BBTMF can pump enough air to pop you double glazing out, so it comes with several precautionary notes, mainly involving the suction and loss of small pets whilst in the vicinity of your machine.
Drawing an impressive 1400Watts of power, Zalman include a full instruction booklet on how to daisy chain 5 300W PSU's together to power the fan, and you get 50 starter cartridges free to get it spinning in the first place.
