First of all, thank you for your hard work.... and then my problem is no fans detect in application macs fan control ,so the fans are loud sometimes, just like the sea wave. so I want control it when it up to the point temperature, it will spin some rpm. It also can't detect in the other system manager software such as istats, lemon cleaner, they all shows N/A in fans module. the picture below will show the detail what I said, sorry for my poor English. image image image image

I haven't done any work on fans, since the default fan handling is done by the BIOS/ACPI/EC. This would be a good issue to work on if you like @uncle-link.

See e.g. KNNSpeed's 9560 guide for getting temperature sensors to work: https://www.tonymacx86.com/threads/guide-dell-xps-15-9560-4k-touch-1tb-ssd-32gb-ram-100-adobergb.224486/

I imagine something similar is needed for fans on the 9570.

Having looked into fans a bit more, it seems this issue is actually quite complicated. You would have to read fan info from ACPI, then emulate the necessary info using VirtualSMC. Both parts would need work.

If fan control is important to you, I encourage you figure out how it can be done and submit a pull request.
