19" 3U rack mount fan unit with 2x ebm-papst 4650N fans *worn fans*

A cooler coil is a heat-exchange device used to transfer heat from a working fluid (often coolant) to the surrounding air. Commonly found in vehicles, machinery, and industrial cooling systems, its primary function is to prevent overheating of engines or other components by dissipating excess heat.

This particular unit has fans, which emit some small rattling like noise. So they are not in the best or worst condition, but rather somewhere in between and still usable state.
