This is a basic 40mm fan adapter for Sega NAOMI hardware. The stock fan often is extremely loud and worn out, by now. This will allow you to easily fit a 40mm (Noctua) fan after repinning the wiring to match that of the NAOMI.

You will need to file/cut 2 opposite corners off the Nocuta fan, in order to use the original fan mounting screws, to the heatsink. I was pretty aggressive, but you don't need to take off a lot. 

The fan itself is friction-fit, but you may need to adjust based on the accuracy of your printer. For me it was just ever so small and held the fan securely. A little hot glue wouldn't hurt, along the edges.

YOU WILL NEED TO REPIN THE FAN CONNECTOR FOR THE NAOMI.

Recommend high temperature resistance material - I am using ASA.
