I would like to buy 6, or however many fans you would recommend to cool 3x open air rigs via "appropriate" positioning of said fans.

Please send me a PM with a Bitcoin payment address with the total number of fans (if you recommend a different count), total, and price per unit, and I'll reply with my shipping and contact details, along with proof of payment.  My zip code is 44138.

(Assuming that's how this works, of course )

Appreciate the service.  I'm told that Delta fans really have no equal

Cheers.
