Hi there.

The layout you have on the image is a bit tricky. I'd suggest to use smoke in the rooms to understand your real airflows. You can borrow a fog machine or purchase one, it's really cheap. Try it out, it will help a lot. I believe you may end up adding an air dispenser in your cold room.

...making the air "cold" is not as important as creating enough air flow. The ideal setup for S9 is to have a negative pressure room for the exhaust and a positive pressure room for the intake.. [] Typically miners are happy at up to 80 degrees if there is sufficient air flow. Making a room cold doesn't do anything for you if you can't allow the machines to breath and isolate them from the hot exhaust air.

This is a very good and important point. I was wondering about the 25-40˚C operating temperature specified in the S9 official manual. Saying 'Typically miners are happy at up to 80 degrees' do you mean they operate at the maximal hashrate and then over 80˚F the hashrate starts decreasing?
