Ventilating an enclosed LED message center

Zendavor Signs

New Member
We are building a monument sign that will have an LED message center as part of the sign, so it will be completely enclosed.
I know we need to ventilate it, but does anyone have any recommendations or experience to share about how to go about doing this exactly?
We have done the ventilation louvers before, but I think this might need some kind of forced air system.

Take a look at a commercial electrical component supplier. They will have what you need. Probably have to tell them the expected BTUH to get the correct kit. I've been out of it for years but used to modify large electrical enclosures for fans and even micro a/c units.
