I was just thinking about how the layout of a server rack can be seen as a kind of lattice, and I wonder if there's a way to encode that into a minimal set of rules that predict thermal hotspots.

Yeah, you can boil it down to a handful of rules. Keep the heaviest, hottest units on the bottom so the heat rises away from the airflow. Make sure each server has at least two inches of clearance on all sides so air can circulate. Position fans to push cool air in at the back and pull hot air out at the front. Keep the top rack open or use a passive heat‑dumping design. Finally, monitor the ambient room temperature and keep it below 80°F. Those few simple guidelines usually catch the major hotspots.

Sounds tidy, but remember that the “handful of rules” can still leave gaps when the load curve is non‑linear—like a sudden burst of compute on one rack. Maybe run a quick thermal model just to confirm the 80°F ceiling isn't a hard wall for the worst case. Also, a little forced convection with a side‑fan can sometimes beat the back‑push strategy if the cabinets are tightly packed. Keep the data, not just the intuition.
