No Fan. Not at all.

The cube was "convection cooled." The heat it generated caused an upward air draft. The negative pressure generated by the air movement sucked in cool air through the bottom of the machine.

The G4 cpu it used was, for the time, both fast and power-efficient. Partly because it ran at such low clock speeds. The power supply was external, and there were not PCI cards or extra drives to generate heat inside the case.

Current chips are much bigger (more transistors) and are clocked much higher. Thus, they generate much more heat than the old G4s.
