well thanks to This post I now know the cable is indeed not long enough. and so far I’ve yet to find a way to extend it. Only way I would be able to get it to reach is basically designing it by having the screen on the underside like the framework 12 in tablet mode. This however cover the vents. so I got a different question now.
Would opening up the side that are normally under the input cover as airflow vents give adequate cooling? I dont know how these fans work and if this side only pushes out air or not.
Edit: To simplify my question. can the fan on the mainboard pull air from both top and bottom?
