Thank you very much for your config!
Looks good to me :)

I guess this one is based on the HP Laptop 17-by1xxx config?

It is the same as HP Laptop 14-cm0xxx and it works very well.

This config doesnt utilize the full range of the fan,
The 100% value is the value reached at full CPU load. However the fan can spin faster. The CPU gets throttled when it reaches ~75° C, but if you let it reach 84° C (with Ryzen Controller) the fan starts to spin a lot faster, reaching ~151%. Tested on a HP 14 dk0007ng.

OK, then please edit the configuration using the high temperature. I was not able to test the fan speed at 84 degrees, and I did not pay attention to these circumstances. I'm sorry about that.

@Metaln00b Is this config file just a copy of the 14-cm or did you do a DSDT analysis / EC probing?

It is just a copy. In my eyes it went well and my fan was running at 100%. I did not know that it could run even faster.

The decimal min/max read values I found are 0 and 16. Strangely, when the fan starts turning, its already at 50%. Feels like one bit is indicating if the fan is turning. This causes the read and write value to be different. You set it to 20% and its already at 50%. @hirschmann have you noticed similar behavior on other laptops?
The decimal min/max write values I found are 46 and 87. 87 is the value if I let the CPU reach 84° C. This does not mean that this is the fastest that the fan can go, but I don't want to push my CPU further than it has to and I also don't want to write values without knowing that they work.
