forced air on the intake side is useless, the miners only flow so much. You need to 100% focus on removing hot air and letting the miners pull the ambient air in for themselves.

Not completely true;
Take a look at my "small home farm" topic setup.

My experience is that when hot and cold side are really isolated, you can use "push-in" air. It equalised the temps of the miners within a few degrees from each other.
What you really need to do, is check the CFM of the used fan, and compare it with the 300cfm for each s9.
If you move less, they are sufficating, and its easy: the strongest wins and gets the most air, and won't frie. The less powerful one heats up. Temps will be further apart from eachother.

If i take a look right now at my miners in Awesome miner program, they are all within 4 degrees celcius from eachother. I have one hotter, and one colder one, wich is specifically miner related. All others are as good as equal.
My compartiments are truly separated.

I wll use a bigger fan this weekend to see if temps get further down, and this way i hope to shutdown my suction fan and use push-in air only.
