thingiverse

Here is the rewritten text: Upgrade to a standard small and noisy motherboard fan with a 92mm Silent Fan. The upgrade consists of three printed parts, a 92mm fan, a step-down converter, and a few screws and small parts. - Fan Plate: The plate has the correct holes for this fan -> BE QUIET PURE WINGS 2 92mm PC FAN - Conrad Product Number 1170667 - EAN 4260052183380. It is mountable on both sides, and the fan can be attached to the original cover or like me with three M3x30mm spacers and a new printed cover. There are holes on the plate for securing a standard step-down converter (LM2596S). The trim pot is accessible from outside through a hole. I have regulated it to nearly 5V, so the fan runs reliably and has enough power despite being silent. A clip with a cable tie is also printed directly onto the board. To connect the original fan cable, cut it off and connect it to the step-down converter. - Spacer: The thicker fan makes the case too wide in the printing area, and the bed could collide with it. There is a spacer that moves the motherboard plate outward. You need three M5x45mm screws for fixation. - Cover: If you choose the fan outside, use the original cover. For mounting like on the pictures, with the fan inside, you need to print a new cover. This also seals better on the side. The airflow passes by the stepper motors and exits through the ENDER logo.
