They will get hot. If you hear a ticking sound from the motors, they could be shutting down.
100°F is not too hot. It is that hot outside here :-). They should be able to run above 125F.
It has nothing to do with the board. You should change they value below 255 if you want high current. Motors draw the most power when idle.

Yeah, I haven't run the current up and tried holding the motors. I'll try that and see if they start to really cook. FYI, It's not the motor that's heating up but the driver

@tgirard Yes, I was talking about the drivers too, but if the drivers overheat they will cycle on and off. That will cause a ticking sound in the motors as the coils pop on and off.
Motors can get very hot without damage. Most of the time hot motors will damage something else like plastic parts, pulleys and belts.
I melted a motor through a plastic table once during testing. Motors was fine, table not so much.

@bdring Yeah, I melted a 3D printed mount with a hot motor.
