SudsMaker Posted April 22, 2022 Share Posted April 22, 2022 I have a new AIO which the pump is showing the lights are working and iCUE shows the liquid and the lights are working. However, the 3 fans attached to the radiator are all spinning but there is no lighting. The fans show up in iCue under Cooling with their RPM as expected. I am using the cables that came with the unit to connect the 3 fans. What am I missing? iCue - Hardware Lights shows the pump only. Link to comment Share on other sites More sharing options...

My apologies, I have a "Corsair H150i Pro XT 360mm RBG liquid cooler" Also, I noticed the "tach cable" only has one wire, I assume that is correct...

Corsair Employees Corsair Notepad Posted April 25, 2022 Corsair Employees Share Posted April 25, 2022 The H150i RGB Pro XT cooler only had RGB on the pump and not the fans which would be why they are not lighting up. Link to comment Share on other sites More sharing options...
Corsair Employees Corsair LandLubber Posted April 25, 2022 Corsair Employees Share Posted April 25, 2022 @SudsMaker Since you asked about the cable: Yes, it's correct that it only has one wire since this cable is only meant for reporting the pump RPM to your motherboard so it knows that a CPU cooler is installed and doesn't display a CPU fan error during boot.

Blane Posted May 11, 2022 Share Posted May 11, 2022 Re the tach cable from the H150i RGB pro XT pump header...What pin on the CPU_FAN header should it be connected to?? I have a CROSSHAIR VIII HERO (WI-FI) board and the 'tach' wire is going to the FAN IN pin on the board. The BIOS shows the CPU fan @ 4300Rpm...Should it not be connected to the PWM pin on the board??

Corsair Employees Corsair Notepad Posted May 11, 2022 Corsair Employees Share Posted May 11, 2022 Its purely a tach reading and is connected to the correct pin. If you want control over the pump speed you must utilize the iCUE software. Link to comment Share on other sites More sharing options...
