damnit, i just found out gigabyte has launched another model for 2070 super windforce oc which is called windforce oc 3x (GV-N207SWF3OC-8GD, rather than GV-N207SWF3OC-8GC).
the new revision has some features cut, like rgb and type c and from 6 heatpipes to now 5 hp only.
but, the whole heatsink of this new 3x model got significant upgrade on thickness, making it now >2 slot instead of <2 slot on the old model.
so the 3x model should have the same thickness like gaming oc model.
it is very interesting to see whether the number of heatpipe matters or the thickness of the heatsink determines the cooling performance.
