jht05016 Posted December 26, 2020 Share Posted December 26, 2020 Hello and thank you in advance for any help. I had installed a H150I Elite a few months ago and using the included commander core, I setup a total of 6 fans. 2 front, 3 rad and one rear exhaust. the 3 rad fans are the ML120s that came with the set and the 3 intake/exhaust fans are LL120. All RGB work as expected and gets detected perfectly by ICUE... However when I look at ICUE, I can only see 5 fans and the pump. so the RGB on the rear case exhaust fan works fine, but I have no PWM control of it through Icue. I have tried updating, uninstalling software, removing commander and reinstalling. Anyone experience this and have some advise? Thank you! Link to comment Share on other sites More sharing options...
c-attack Posted December 26, 2020 Share Posted December 26, 2020 Is the missing fan spinning or stopped? The Commander Core appears to use some type of auto-detect on the PWM side as well. Trying doing a full shutdown, then disconnect and reconnect the PWM fan that is missing. See if it shows up on next OS load. The power cycle to the device is necessary to trigger a re-detect of the PWM side of the fans. Link to comment Share on other sites More sharing options...

It is powered up, spinning at full speed since there is no speed control while the commander isn’t recognizing it. Link to comment Share on other sites More sharing options...
c-attack Posted December 26, 2020 Share Posted December 26, 2020 So what we are trying to figure out is if there is a problem with the tachometer wire on the one fan (no speed reported) or if this is just finicky detection behavior from the Commander Core. Disconnect the missing fan from the Commander and connect it to any motherboard header. If the tachometer wire is damaged, it won't show up there either. If it does give a speed there, move a different PWM fan to the problem header on the Com Core to see if there is a specific problem with that header.
