Just tested temperature of stepper and  driver.

After one hour of working TMC2130 had temperature 88C. I checked datasheet and it is ok. (Overheat protection should started from 100 to 120 degree.) I think we doesn't need active cooling here. May be in future I add some additional holes in box.

Different situation at stepper:

72C not too bad for NEMA 17 stepper (depends on class working temperature is 105-180C) but since it is 3d printable 72 it is maximum for PTEG. I decided to add 40mm cooler fan.

Image changes after one hour of work 41C.
