Duet 2 Wifi - connection and settings aqua cooling kit

I have question about wiring and settings in firmware for Aqua cooling kit from alliexpress:
Is it possible connect into the Duet 2 Wifi? I am not sure, because this kit has 4 pins:
Thank you for your answer.
Best regards Radek

It might work by just hooking up fan pin 1&2 to the Duet. Speed control may or may not be possible, which may or may not be possible to work around by wiring pin 2&4 both to the positive pin on the Duet, and fan pin 1 to the negative pin on the Duet. (I think).
Edit; need to get 12v/24v right, and be sure to get the polarity right otherwise the fan will most likely die silently.
https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans#Section_Connecting_4_wire_fans Suggests tying the PWM input to negative instead of positive. Also has info on how to connect the RPM feedback.
Yes, connect it as either a 2-wire fan (using just red and black wires), or as a 4-wire fan as explained on that wiki page.
