Just finished the Antminer Hood H1. 
Running a couple Habaneros at 1.4TH/s combined down below as well.

Are Antminer fans pulling air? If not where is all the hot air going?
Oh I missed that. But still it looks like the exhaust duct is a bit too small. I see that it's pulling air from both left and right, but it's size is only a half of antminer for each side.
Ants are pulling air from front towards back. The bottom of the hood is open as well. Top is 6" duct with a 400cfm turbine exhausting the air.
Ants actually went up 1 degree in temp, but ambient came down 10 degrees, so my wife and my habaneros are running much happier.
