correct me if im wrong but dont the ants already come with fans... why the need to purchase new ones...? also is it recommended to purchase a big one to blow on all of them...? do they over heat quick / often...?
I put a $69.99-20% coupon=$60 (including tax) Vornado fan from Bed bath and Beyond behind three ants grouped together (you can put another three on top of first three). Cost-$10-20/ant. Ants cool down so there is only 2000-2100rpm+fan (which is relatively quiet on medium setting). The whole setup is just 60db in 1-2 ft distance, which is fine even to be in the same room (tolerable). No squealing of accelerating fans even at 375mhz (did not check higher).
