Hi,
It seems like it is only the SYS_FAN1 and SYS_FAN3 that can be controlled (PWM) from operating system in my case Linux.

Is this how it should be?

It the BIOS it seems like SYS_FAN1-SYS_FAN4 should be possible to control but infact it is only SYS_FAN1 and SYS_FAN3.

In addition the CPU_FAN1 can also be controlled (PWM) from the operating system.

I am running the T13 BIOS.

Would it be possible to implement so that more SYS_FANs could be controlled (PWM) by the operating system, or is there a work around?

Thanks in advance!

    We will attempt additional testing on this feature. From what I recall, previous test records showed that the speed of all fans could be controlled. I will update this issue in the wiki subsequently.

    Hi @loodd,
    Let me know if you want to provide information with pictures and a list from the pwm directory when IT87 driver is loaded in Debian.

    Also the pictures in the BIOS on the wiki  https://doc.x86pi.cn/#/docs/fs/VXCQuW3XQSosL8RRJL2ixp/235 do not reflect how it look lke in the BIOS T13.

    Let me know when you have an update.

    Thanks!
