Please read the Shop website of the Cable.
https://shop.aquacomputer.de/product_inf…roducts_id=3607
The cable is only compatible with the listed devices on the shop site. It does not work anywhere else.
The aquaero is not listed, so the cable does not work on the aquaero.
The mainboard cpu header is not listed, so the cable does not work on the mainboard cpu header. (it will damage your mainboard if you connect the cable to the cpu header)
So i connect it to the pumps RPM connection even when the pump is connected to the Aquero?
Yes.
And if so,i can not use the Aquero RPM connection anymore for the mobo cpu fan header because i connected the Connection cable alarm header to motherboard power switch header (53217) to it?
You have to connect the cable from the Aquastream Ultimate RPM Connector to the mainboard PWRBTN connector.
see the attached picture.
Please read the Mainboard Manual (section is called the "System Panel Connector" ) to find the correct Pins for the PWRBTN on the mainboard.
Warning: Before connecting the cable, make sure the RPM/alarm header of the Aquastream Pump is configured correctly!
Configuration for aquastream ULTIMATE (aquasuite Software): Tab "Alarms": "Power switch (53217)" has to be activated.
