Carefully install the new shroud on the printer, ensuring it is properly seated and secured. Double-check that all screws are tightened firmly to avoid any vibrations during printing.

Upgrading the Mainboard and PSU Fans

Next, upgrade the mainboard and PSU fans by replacing them with the new Noctua fans. Open the printer case and drill holes for ventilation and fan mounting. Take care not to damage any of the components or wiring during this process.
