i dont understand how you only get 10 gh from 14 rigs


about the cooling

1 water cooling is stupid
2 air cooling is the way to go
3 i suppose that you cant use some natural cooling in your place http://www.csia.org/HomeownerResources/ChimneySafetyInfo/HowYourChimneyWorks/tabid/114/Default.aspx


whats the best way in my opinion ?? a air pump (connected to a tank ? ) and split the exit to little tube for each card, ac is a waste of money on electricity
