Ender 3 V2 Noctua Mod

I recommend printing everything on PETG :

Use fans:
Mainboard : 

NOCTUA NF-A8 FLX 12V need a step down converter !!!
 

PSU:

NOCTUA NF-R8 redux 1800 12V does not need any change for PSU !!!

Printers is several times quieter, the problem with a defective board has been solved(layer shifting 4.2.2.)  when given proper cooling
