Wakefield DS0402812V2B-BT0 30000 RPM "The Monster"
Product number:
RT10201
Product information "Wakefield DS0402812V2B-BT0 30000 RPM "The Monster""
40x40x28mm fan for use in the Nevermore Mini. Extremely powerful fan which can be controlled via the PWM pin down to sub-10%. The performance of this fan is extremely high, so is it's noise, hence "The Monster". Mount the fan prior turning it on, it will probably jump at you.
This fan is loud, fast and draws 3A at full speed. Using a standard fan output on your controller will probably kill the output, use an appropriate output like a spare hotend output.
The datasheet can be found here.

PWM control follows the standard Intel Spec (5V pullup, 25kHz signal). If no signal is given via the PWM input, the fan will run at full speed. Relevant config options for Klipper:
tachometer_pin: # Set to the pin you like to use. Make sure it has either a hardware or software pullup tachometer_ppr: 2 tachometer_poll_interval: 0.001 cycle_time: 0.00004 hardware_pwm: true # Hardware PWM is preferred if your board is capable of it
