Extruder stepper motor gets very hot - too hot?

The extruder stepper motor gets very hot after ~2 hours of constant printing. I cannot touch the metal cover for more than ~5 seconds and then it hurts badly in my fingers. Is this temperature "normal"( I know we all have different level of resisting pain 🙂 ) for your stepper motor?

I posted a picture from thermal cam somewhere here on the forum. It is around 70°C, which is completely fine for the motor and won't hurt it's performance 🙂

Did you print something cool already?
