Missing CPU fan within fan control

[gandalfwfh]

Hi,
I have 4 fans connected (each is based of 3 fans cascaded) 1 on the fans is connected to the CPU
fan header and it belongs to the AIO radiator.
the AIO pump is connected next to the CPU fan header. I can see all the fans and the AIO fan but not the CPU fan. in the bios I can see this fan and change the speed with no issues. this seems like something quite easy to solve but I am quite new with all this (just finished building the computer), any idea what I am missing here.

This is defiantly not fan control specific issue , I also don't see this fan using Libre hardware monitor.

installing Asus AI suite 3 all the fans are present and working except on fan control , both cpu fan and cpu opt fan are not showing in fan control

You pretty much got the cause. What exactly do you want/expect out of this discussion?

unfortunately I didn't got the cause , its not working using fan control but works with another program which means its not an hardware issue. if I am trying to get your point , its ok than use other software.

I said that because you figured out it didn't work with LHM, and Fancontrol uses LHM internally for everything hardware related.

Disconnecting CPU_OPT (gpu aio) fans solved the issue.
Thanks
