I guess the square one could be mounted inside the roof on the underside of the roof vent.
You wouldnt want anything as heavy as that. Plenty of small high flow fans available for the job that wont weigh much. You could even use some of the hardcore computer fans as a lot of the higher end stuff is water proof now and definitely high enough flow to deal with all those nutters with super hot PC's and water cooling etc.
