Do I Need an Extruder Motor Fan If I Build Enclosure Over Print Area?

Do I Need an Extruder Motor Fan If I Build an Enclosure Over Print Area? Normal printing and open heatbed my motors do not get hot at all. Perhaps not 100% closed, but something against drafts.

If you planning on printing ABS all the time with an enclosure at 100~120 then you will need a heatsink and a fan, if you looking for an enclosure temperature between 60~80 degrees then just the heatsink. A fan only cooling system is inefficient.

Besides that, you'd have to pump in air from the outside of the box to get cool air.

Or design an enclosure that has a bounding box that keeps out the motors (and use bowden for extruder so that too sits outside the box).
