I just added a high flow next and a splitty 9 active to my existing loop that has d5 next 150 reservoir and leakshield. The high flow next is working correctly it is connected to the splitty 9 with the appropriate cable connecting the signal output on the high flow next to the input on the splitty 9 active. After installation I fired up the computer and was greeted with a message to upgrade the firmware on both new devices I clicked on the high flow next to update it then restarted expecting to be prompted for the splitty 9 next but it never popped up again and it is not showing in the aquasuite software or device manager. My fans are all running 100% I'm guessing the default. when I go into aquasuite / d5 next / sensors / flow / sensor type. the high flow next isn't one of the options. Any help or advice would be greatly appreciated

Thank you for the response. after researching all night I did figure out that it is passive as you said my mistake. the highflow next isn't a fan controller but it will send a fan speed signal that is synced with the flow speed, but that is not what I want. so I guess to get full fan control I will have to connect the splitty to the D5. The reason I didn't go that way first is due to the inability to get to the connection on the D5 without disassembling the entire computer. I have a cable that has these pwm connectors on both ends is this the correct end for the D5 fan output. I just want to be sure I have what I need prior to starting this nightmare.
