Thank you!  Please create one more round of the Embedded Controller Dump to let us see how the registers change between two instances of issuing the dump.  Thanks.

[Iceberg]

Yes, done! Some values really changed.

I get two dumps: v2 on idle, v3 - on high FAN load. Thank you for your attention and help.

Thank you!  I'm afraid we haven't found a reliable method to measure fan speeds on your system.  We've contacted Minisforum about this issue, but they refused to provide the necessary technical information on the fan measurement

[Iceberg]

Dear Fiery!

Thanks a lot for research for this case about Minisforum MS-A1 fans. It's a pity that this company's technical support treats its users like this. Next time I'll think twice about buying their products. Thank you!

Hi The Minisforum EC controller can using CMDIO: 0x6C  DATAIO: 0x68 to commuticate with it.

FAN Speed and Temp Interface Read Datasheet:

CMD: 0xDD

Data: 

0x20	Get CPU DTS temperature	EC return temperature to tool
0x21	Thermal Seneor For MotherBoard	EC return temperature to tool

 

CMD: 0xD5 

Data: 

0x14	Get fan3 speed (low byte) motherboard	EC will return to tool fan3 speed (low byte)
0x15	Get fan3 speed (high byte)  motherboard	EC will return to tool fan3 speed (high byte)
0x16	Get fan2 speed (low byte) motherboard	EC will return to tool fan2 speed (low byte)
0x17	Get fan2 speed (high byte)  motherboard	EC will return to tool fan2 speed (high byte)
0x18	Get fan1 speed (low byte)  Cpu	EC will return to tool fan1 speed (low byte)
0x19	Get fan1 speed (high byte)  Cpu	EC will return to tool fan1 speed (high byte)

Good news! Can we expect this in new build?

Thank you!  Based on that it's not 100% clear to us how the communication needs to be performed on the ISA port I/O level.  Can you please contact us directly and send us the datasheet that includes the information above?
