Cooling Basics: Why Hot Air Is the Enemy | Lesson 11

Every watt a server drinks comes back out as heat. This lesson opens the cooling module with the law that rules it all: the balance law, watt for watt. You will see why a rack is really a heater that happens to compute, how air works as the courier that carries heat away, and the cooling chain — air, water, outside — that never gets to stop. A worked example runs the numbers on one 10 kW rack.
