Mark,
Huh? Cooling? This is no antique fan and it is certainly not for cooling....you have probably heard of a "base trap" well this is actually a "base mixer" ... my most expensive audio tweak.....it evenly distributes the lower base frequencies evenly through my room.
Since I upgraded the pulley system from ordinary rubber to directionaly aligned genuine cow hide leather, the smoothness in base reponse has been phenominal...with this tweak I think I have nearly achieved audio nirvana...although I find it a nuisance to continually adjust the rotation speed to match the sound level and once I nearly lost a finger when my wife hit what she thought was the light switch and started the rotor just as I was making critical phase adjustments of the blades.
