Green - stock cooling and drivers.
Grey - new cooling and TMC2208.
It's much better than the stock cooling and will greatly improve Your print quality.
If You want to make Your printer super silent You will need to swap original fans.
If the specification is right, they should be silent. There is no 24V silent fans from famous brands like Noctua but as the motherboard fan and prinhead fan should be powered directly from the psu You can connect two 12V fans in series and it should work just fine.
You can find marlin for this setup in the download section. If You want to use Linear Advance with TMC2208 You need to set MINIMUM_STEPPER_PULSE for 1 in Configuration_adv.h.
LCD plug needs to be connected upside down. Yeah, that's weird but trust me. There may be a need to cut latch off.
Card reader needs to be glued to new box. I have used epoxy glue and it's holding well.
Sd card reader needs to be connected via AUX-3 pins. Pin CS should be connected to pin 53, the rest is obvious. If it's not I do not recommend this mod to You. Make better cooling duct and You will be happy with the results.
Place supports only in USB and sd card slot.
