<hardware> /heet sink/ (from "sink", electronics jargon for something
which takes in current) A piece of thermally conductive metal attached to a
semiconductor or other electronic device and designed to prevent it from
overheating by conducting heat away from it and radiating it to the environment.
Heat sinks often have fins to increase their surface area. They occasionally
have fans attached. Heat sink compound can be smeared between the device and the
heat sink to improve thermal conduction.
