Question Which Motherboard Header For New AIO

[yanna1]

Hi, I have just purchased the Corsair h115i Elite Capellix AIO. This is my first every AIO and will be replacing my stock AMD Wraith Prism.

I was wondering what motherboard header should the pump tach cable be plugged into?

Currently the wraith prism is in the CPU_Fan1 header. I know the Corsair instructions say to plugged it into CPU_Fan header but what about the Pump_Fan1 or Sys_Fan1 headers?

Would be great if someone could confirm which header but would also I would be interest knowing what the other two would be used for.

Sorry I was trying to upload pictures of the instructions but I couldn't get that to work.

Thank you

CPU - Ryzen 7700
Motherboard - MAG B650M MORTAR WIFI
Ram - 32GB(2x16gb) DDR5
GPU - Sapphire Radeon RX 7800 XT PURE 16GB
PSU - Corsair RM1000X

Follow through steps outlined in page 32~34 in your AIO's manual.

Yes it's CPU_FAN header on your motherboard.

Brilliant. Thanks for confirming.

Lutfij told you the answer. FYI, the why?

In the Corsair AIO system their iCUE software takes over all control of CPU cooling, and uses a cable from their Commander Core unit to a mobo USB2 header for communicating with the system. One piece of info that iCUE needs (and so does the mobo itself) is the speed signal of the critical component of the CPU cooling system, and that is the PUMP. iCUE expects to find that from the mobo CPU_FAN header. So that is where the Pump's speed signal cable is to be plugged in.

Thanks for that extra info. Always useful to learn.
