Air Purifier
Hello, does anyone know how I’d go about connecting this fan (https://www.amazon.com/dp/B07CG2PGY6/ref=cm_sw_r_cp_api_glt_fabc_l-fdGb1QVWHBM?_encoding=UTF8&psc= 1" target="true">Noctua NF-P12 redux-1700 PWM, High Performance Cooling Fan, 4-Pin, 1700 RPM) to my MK3S if it’s even possible? I’m using it as an air purifier for my enclosure and I want it to turn on when my printer turns on. Any suggestions?
RE: Air Purifier
This appears to be a 12 volt PWM controlled 120mm square fan.
Your Mk3 Printer is a 24 volt printer. so there is no direct power source to drive the fan.
there are 4 wires
Ground
+12 Volts,
Tacho signal
PWM signal
Noctua see, to say that you can use a 4 pin fan where you would normally use a 3pin fan. so I expect that you could run this fan with Just +12volts and Ground ( the tacho pin is an output that you can simply ignore... ) But you don't have 12 volts on a Prusa Mk3 Printer. You could use an external wall wart to drive the fan, and just turn on the fan, when you want it... If you have a 2 socket extension lead, you could use the wall switch to turn everything on and off together.
Or you could get a DC tp DC Buck Convertor and drop the 24 volts off the power supply to 12 volts for the fan.
your normal printer fans are 5 volts, so their supply is not suiteble
