This cable allows you to replace the stock 40mm fan on the 3DO FZ-1 with a quiet aftermarket one like the Noctua 12v 40mm.
NOTE: Only the North America FZ-1 came with a fan preinstalled. If you have a PAL or JP region machine, they didn't come with fans preinstalled and the header on the motherboard and supporting components are missing. So unless you want to add those back in, consider this cable just for North America consoles that had fans factory installed.
