In theory it is for cooling. The outer smaller vents route some air to the fender well but I don't think there are further guides to force the air to the rotors like you might expect there to be. The bigger vent that is on all the p10s with the factory lip directs air to the front of the gearbox. Later versions of the gearbox, but not on the p10 itself, actually has a bunch of cooling fins and the gearbox case.
