Minisforum AI X1 Pro has missing CPU fan and missing case fan support with AIDA64 7.99 7809beta

[Antiram]

Hello
I use a Ryzon AI 9 HX 370 based Mini PC.
It is the Minisforum AI X1 Pro with an AMI Bios
The PC does not recognize a CPU fan or a case fan with myfull version of AIDA64 7.99 7809beta.

There is no option to choose a CPU fan or a case fan with my machine.

All other stuff is working fine.
I used the latest Beta because I own a Turzx 5 " display

Is it possible to add those fans ?

Regards David

In AIDA64 please press Ctrl+D --> Sensor Debug --> ISA Sensor Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post.

Also in AIDA64 please press Ctrl+D --> Sensor Debug --> Embedded Controller Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post.

Thanks,

Thank you!  I'm afraid we cannot find the relevant registers that could be used to measure fan RPM on your system We'd need help from the manufacturer of the device, Minisforum to solve this issue.

Ok thanks. I send an Email to the Minisforum support.
Hope they will help.

Looks like Minisforum support will not help.

That´s sad. 
Any other idea ?

I could do a logfile again with different fan speeds doing full CPU load or nothing.

Would that help ?

That's a pity I'm afraid we're stuck since we're 99% sure the method would involve writing a value to one of the Embedded Controller (EC) registers and then read the fan RPM value from another register.  But without knowing the register indexes and values, it's a huge number of combination that we'd have to try.  And brute-force trying to write to EC would also risk damaging the hardware too, so it's a no-go
