Twotrees Sapphire Plus SP-5 v1.1 120mm controller fan adapter

Mount to replace the internal 40mm with a 120mm fan for much quieter operation.
Uses the existing screw mounts; a strip of double-sided tape may be required to support the far end if you have a heavy fan. 

Important: this is for the 2022 version Sapphire Plus, officially called the SP-5 v1.1 / v2.1. This fan adapter would need basic modification to fit the older models as the fan and mcu orientation are different.
