in the MAC would be beneficial for cooling ? Running my mac near the limits I am trying to figure out some way other then
filling it with oil to help keep it cooler or reduce cooling times between runs.
I used thermal glue to attach heat sink fins to my geared hub bafang motor.

heres a photo.

the aluminum fins definitely help dissipate heat, because they got hot after riding the ebike for a long commute.
