So the one at the "back" is getting pre-warmed air. Wouldn't this be a problem?

*Note I am used to normal data-centers but not high density stuff. I don't know of the special provisions a high-density setup would have.

In general, high-density or supercompute systems are installed with custom racks, cooling, power supplies, etc. This doesn't need anything custom, just something that isn't always the default in some DCs.

They're ARMs, they don't need much cooling anyway.
