Replacement fan, still noisy and I then upgraded to an after market quiet computer fan, dropping the voltage using a 1W resistor is easy and works a treat, printer is so quiet now with extruder fans on, now I need to find a turbo fan replacement and power supply fan to make the printer super quiet.
When replacing fans, I cut wires and made a connector system, enabling fast swap out in future, FlashForge creator pro could do with an upgrade kit to allow a break-out box set up above the extruder, would work wonders for servicing the printer. Maybe I’ll make one :)
