I highly recommend the book Pandora’s Star by Peter Hamilton. They explore using tiny wormholes. They move them, poke a powerful sensor suite though, scan, retract, and close, gradually moving in on prospective planets. They have powerful forcefield to protect against anything coming in the other way. Makes sense to me.
That makes sense to me… You really only want one path for the air flow. E g. In through the front, over the components, and out the back.
Most of the fans in this setup are just fighting against each other.
