Fan

Some router models do not have a fan, while other models have either one or two fans.
The fans spin at full speed, as a diagnostic aid, immediately after the router is powered up. After the
router has booted, the fans spin as fast as necessary to minimize fan noise while maintaining a safe
internal operating temperature.
