    My layout is a mirror image of that because the VFD air inlet is on the left. I cut out a large hole in the side of the enclosure next to it to allow the air straight in to the VFD and the it exhausts out of a hole directly above it. That stops it drawing warm air from the enclosure.

    I allowed 2 80mm fan sized holes in the base of the enclosure below the drivers but never added the fans as they barely get warm. Natural convection seems to work fine although we are in the UK so it does not get that hot.
