Fan won't turn off

[V0RT3X]

MMM

Plug everything it, flip the switch, all the usual beeps but the fan will not stop. Always spins, even if I start it the next day. Thought it was getting hot but I don't think that's the case, 6S 5000 30C with 1520 geared for 38-40mph. (Flux XL)

Not that it's a big deal but can something be dead inside? (like the thermal sensor)

Temps on motor after hard run were 50°C and the ESC about the same(at the motor bullets), lipos were 30°C max.
