Hey, i have a problem with my cpu fan rpm.
I have an aio from deepcool and i have the 3 fans in a hub and the hub is on the cpu fan header but it shows no rpm in bios or software.
It does respond to the curve i have made, but shows nothing, not even when ramping up the speed.
I have 6 other fans connected also through a hub and on chassis header and they do show rpm, all the fans are from deepcool.

Is there a solution to see the rpm of the cpu header?
All the fans are on pwm mode, the watercooler pump is on dc (3 pin)
Also none of my case fans (9 of them) are not showing in apps like openhardwaremonitor, on my older mobo they all showed up (asrock B560).

I hope someone can help me with this problem.

Thanks.

I have the latest version of the bios.
I tried the program you advised and only the mentioned fans are showing, so only the pump fan and chassis fans.
cpu fan is not showing in bios or in hwinfo64.

I solved the problem, apparently the fan hub has only one port that registers rpm, and i did not have a cable inserted in that port, so when i did, the bios registered a reading :)
