I did remove all the fans ..
and so far working well ....

Nice layout.
One fan cooling all 10 pods. Nice.
I'm cooling 5 pods with one pod with fan in the center and 4 pods without fan surrounding it.
Running at a decent 80* to 91* F in Scrypt only mode.
The cool air that the center fan throws is enough to circulate some air around the other 4.
They're all within 1* of each other.
I'm testing their temps with an infrared temp sensor gun.
So far, so good.
