Finally got it out of the box, setup, explore the new features, amazed at those, and the extreme exhaust fan noise.
So what do I do with this monster that I couldn't do with my ender 3? yup bag clips.

I replaced the idiotically loud motherboard fan with a 24V 40/10 Noctua. It needs slightly longer screws than the stock ones but otherwise it's a drop in replacement. Noise levels are much more acceptable now.
I've been doing some light research and i think it's possible to run the stock fan slower and turn it off when not printing, but it's unclear whether i'd have to plug the fan into a different header or not.
Because the full info is in a private facebook group :bleugh:
Is it running Klipper or something else?
In Klipper I have my controller board fan set to speed up only when there’s any active heaters or stepper drivers?
E.g. fires up only when moving/heating or printing but not when idle. Even then it’s set to a reasonable 80% threshold.
It has klipper but not mainline klipper, looking at some firmware updates that might automagically fix this. gotta confirm what I currently have.
Here’s what that looks like for me. Basically a controller_fan configured to kick off with the steppers.
#Case fan for cooling when heating bed [controller_fan controller_fan] pin: YOUR_FAN_PIN_HERE heater: heater_bed stepper: stepper_x,stepper_y,stepper_z heater_temp: 40.0 fan_speed: 0.8 shutdown_speed: 1.0 kick_start_time: 0.5
Thanks, so in sv08's case, I'll have to open the bottom and plug the fan into another header before updating printer.cfg just like your example.
The firmware update is a .deb file, I know this, it's a ~~unix~~ debian system!
