[Need help with ABS splitting problem]

Hello, I'm trying to print ABS with my cr-10s and keep getting split problem.

 

I'm using Cura 3.6.0, nozzle temperature at 250C, bed temp at 100C with layer height 0.1mm

Extrusion speed is 20mm/s with 2 shells, 10% infill.

 

Regardless of the print size, splitting happened.

I think printing speed isn't that fast and the temperature is high enough.

I didn't check the fan power but I didn't change default setting value of it.

Any help would be appreciated!
