Convection flow requires gravity. Laptops on various space labs
starting with the skylab and Shuttle found out about this. For
convection to work it needs gravity so the lighter heated air
moves *up* being displaced by cooler heavier air. On Mars
no problem except the amount of heat the atmosphere can carry.
