I heard back from the support team at Vertex. Surprise!! we all are wrong. The fan is supposed to blow OUT and pull hot air from the enclosure and blow it out. He said:
There is an internal fan in the compressor that draws air through it to assist in cooling. The case fan is designed to draw the hot air out. It's more effective to blow internal air out, as blowing hot air in adds to the heat and will damage it in the long run.
Went out last night and turned it around..
