You are welcome.
There is 2 fans, one on top one at bottom of the table for air flow.
The switch command the led lights.
The front blue box is a W1209 thermostat for fans.
The rear red lcd is the PSU voltmeter.
Hidden below table an other W1209 regulate the PSU fan.
I didn't installed soundproofing or vibration damping, my 3D printer has silicon pads yet and it's enough for me :)
