there's no power and no control going on with it. The PWM cable from the pump is only a speed reading for the motherboard, so it doesnt beep because you have 0 RPM. I don't want to burn out a header or worse. I feel like plugging it in to the AIO Pump header makes the most sense, but I am unsure if the pump needs more current than 1 amp. The other is named 'W_PUMP+' and operates at max current of 3A and 36w. One is named 'AIO_PUMP' and operates at max current of 1A and max power of 12w. Would it be possible to just plug the commander core in to SATA power, plug the 24-pin pump cable in to the commander core, plug the tach cable in to CPU_FAN header on motherboard and have the pump run at 100% (default)? I would then plug the 3x 140mm fans into headers on the motherboard to control their curves in bios.Īlternatively there are 2 pump headers on my motherboard (Asus Maximus Hero z690). I feel like iCue should not be needed for this.

I have an H170i elite capellix 420mm that I would like to run on 100% pump speed while having control of the fan curves in bios. After having issues with the iCue software, I am looking to uninstall it once and for all.
