Fans of Prusa i3MK3S+ not fast enough for cooling?

Basic Information:

Printer Model: Prusa i3MK3S+
MCU / Printerboard: Einsy
Host / SBC RPi 5

Describe your issue:

Hi, from the OrcaSlicer Preview, especially under Speed, Flow and Fan Speed, I can see that there are two colors. The one at the same layers of vertical holes are darker. In the actual print, same thing. Does Klipper has any function to eliminate this problem? Is it because the fans of the i3MK3S+ not fast enough to cool down the filament? Any good mod or fans that I could buy to replace the stock fans for better performance? Current print speeds: Outer wall 30mm/s, inner wall, sparse and internal solid infill 200 mm/s. Gap infill 30 mm/s, Support and Support interface 80 mm/s.

Hi @printeruser ,

This is a fairly universal 3D printing limitation. To make your outer surfaces print the same speed, you can disable the slow down outer walls setting in filament → cooling settings.
