It's those tiny high-speed (< 1U) fans that are killing you.
Cheapest solution: Move the system out of the room? Have you looked at
just running a network cable to a minimal diskless system for the
in-room needs? I assume those needs are graphic head plus some manner
of sensor input. The in-room unit could boot from the cluster, located
In-room solution, but possibly above your price range: Go to a cluster
builder for a custom solution that removes the p/s and fans from each
box, centralizes the larger and slower fan(s) and p/s in the cabinet,
running dc to each node.
Depending on your skill and labor availability (I did see duke.edu in
your addr), you might be able to do this yourself or get some, um, cheap
