I'm in the process of building the frame for my P10 matrix tune-to sign (4x2), and am contemplating adding some 5V fans to vent the cabinet. My venerable LEDtriks sign was vented at the bottom of the cabinet but I did not use fans to move the air, and I would always end up with condensation on the front plexiglass. I'd like to try to avoid that with my P10 sign if possible.
Does anyone else use fans to vent your tune-to sign cabinets?? I was thinking possibly two fans, mounted on the bottom of the cabinet, one pulling air into the cabinet, and one exhausting air out of the cabinet. My next thought is run time - should I let them run all night to keep airflow moving through the cabinet??
