Unable to control my Alphacool VPP655-PWM

[FTA7700]

I'm using Fan Control for a year now, and anything else is set up and working fine. But never been able to control the pump from that software. I was able to do it from Gigabyte's SIV control software (uninstalled now), but it had it's own bugs and limitations, so I migrated to Fan Control. The pump is attached to the motherboard with 4-pin header (2 wires, tach signal, and pwm control) on that port:

I can see it's rpm in Fan Control, but I'm unable to control it either with forced/fixed setting or with curve attached to sensor.

I'm able though, to control the pump with a software called Argus Monitor, and now im forced to use those two simultaneously.

Motherboard: Gigabyte Z390 Aourus Ultra.

Not sure if any other information will be relevant, but I can provide more if needed.

Any help is appreciated.

Do you have InpOut activated in sensor settings?

Yes, I have.
