Your comment about cooling reminded me of a fun anecdote from my time in academia. My PhD involved quite a lot of high performance computing simulations. We kept running into problems where on warm days, all our jobs would get killed pretty consistently. Our IT guy noticed a pattern where the temps would be perfectly normal, and then suddenly out of nowhere go through the roof, triggering a thermal shutdown of the racks. In the end our IT guy camped out in the server room on a hot day to watch what was happening. The Astrophysics' cabinet were directly infront of ours, and they had jerry rigged their cabinet door so that when it got too hot, it would swing open and their hot air would be blown all over the neighbouring cabinets...
