What should the fan sound like?Updated 11 hours ago

The Pro Laser’s fan sounds like a laptop’s fan. It works like one, as well.

The fan may or may not turn on right away. It turns on when the device needs to cool.

It becomes faster when hot. The sound may change, just like a computer fan.

Only the Pro Laser models have a cooling fan. The Pro Laser has a high energy output. It needs extra airflow to cool down.
