CPU opt fan detect but no RPM shown

[Kashrlyyk]

I have added another fan to my PC and plugged it into "CPU opt". The fan is running but it is shown in HWiNFO with a red cross next to it. No readings are shown too.

The Motherboard is an ASUS Prime X370 Pro.

I used version 8.24-5700 of HWiNFO.

Is there anything I can do?

Red cross means monitoring is disabled . Select the item and hit Ins key.
