iCue software not changing fan speeds on my case fans and they are constantly at around 900 RPM.


Recommended Posts

I am trying to use my Commander CORE to manage my case fans but it seems like they wont change the speed regardless of what I change it to and they are always going super fast. Whenever I change the setting in the iCue app from for example quiet to extreme nothing happens and the fan speeds stay the same. The commander pro is working great with the fans that came with the AIO they just do not control the case fans at all it seems. Any way I can remedy this?

I am  talking about fans 1,2 and 3. those are the case fans. The other 3 are working perfectly.
 
Thanks a lot for any guidance!

What exact fans are you utilizing? Are they 3-pin or 4-pin fan connectors?

That is going to be the issue. The Commander Core and Commander Core XT controllers are not compatible with 3-pin DC fans.

The Commander Core is a PWM (4 pin) only controller.  The Commander Pro can do either 3 pin DC or 4 pin PWM.  Are you able to re-arrange it so your 3 pin fans are all on the Commander Pro for fan control?

I dont have a commander pro I have a commander core or w/e that came with the AIO, I got out a couple of old noctuas and plugged them in and they work like a charm, so it is as you and Corsair Notepad said; they have to be 4 pin. Thanks a lot for the help guys!
