Coil whine on startup but good PoE HAT

Good PoE HAT, RPi 4 stable at 2.147GHz (with optional fan and heatsink) but stable in vented case at 2.0GHz, no low voltage warnings. : The included standoffs and HAT are used to clean low-profile heatsinks and other components. - 2 stars for coil noise on startup and no extra pins to access 5V, 3.3V or GND.

Pros
