As you know the P1P doesn’t come with a cooling fan for the MU. I recently built an enclosure for my P1P and I saw recommendations online that I should install an MU cooling fan since I plan to run hotter extruder temps. I bought the Bambu Lab cooling fan for the X1 because it plugs right into the MU. I installed the new fan but it doesn’t come on. My question is, what should I expect when I turn on the P1P? I get +5v at the plug. Is the fan temp controlled? Having 4 wires at the plug would lead me to believe it is temp controlled but since the P1P didn’t come with a fan in the first place, I have no point of reference and the wiki or manual doesn’t describe how the MU fan is supposed to work.
ive removed the heatbed cable guide and the poop chute and the cover over the psu to get access the psu screw terminals. then i saw there were 2 unpopulated 24v terminals on the psu (+ and -)i could use. ive connected a 24v buck converter to it and adjusted it to 12 volts on the output side, since ive planned to use a bunch of 12 volt stuff on my printer anyways. i just connected a 12v 4010 noctua fan to this 12 volt rail ive created and have that fan always on. you cant hear that tiny thing.
you know the Main board has a port for that fan, and its enabled
with a connector i do not have spares for, and so i do not have to rig something that might break that connector or even board, ive made a direct connection to the PSU i can control with an PID temperature controller, you know
the X! board fan is a drop in fix not modding of anything for the P1P the port is in an odd place on the side but works great
i did not want to use a shabby x1 fan. i use a noctua fan on the heatsink and a 60mm papst on my external air duct system connected to a PID - pwm controller with a temperature probe on the MCU heatsink which controls both fans. i do not run a conventional setup, i need actual environmental temperature controls since the entire printer is not enclosed, but encased.

ok but you can use the same control with that connector its meant for, seems like you over complicated it for no reason
