Original GitHub issue: https://github.com/hirschmann/nbfc/issues/1133

This is the newest laptop of hp up to the year 2021. It has a 3070 GPU and so it is really NOISY.

I tried to follow the steps in How to create a NBFC config but unfortunately failed. I tried to extract the DSDT out but failed. I tried to observe the behavior of EC regs. I get some clue but not enough. I also read carefully Problems creating HP OMEN 15-dc00xxxx config but the registers he mentioned not work for me.

I want its fan to work constantly at 30%, which is 1800rpm. I have known that 0xb7 is the temperature of GPU. This laptop has a "Fan always active" in BIOS. If I set 0xb7 lower the 55 decimal, the fan will work at 50% if "Fan always active" and totally turn off if not "Fan always active".

I also worked out that 0x2e and 0x2f are the current speeds in percent, which are read-only registers and take no effect if I change them.

I used the utils in marhop/fanslow-probook430g2 to control EC registers explicitly.

I badly want this too. HP control program doesn't allow user to lower the rpm below 2900 which is annoying.

I wrote one for my omen here WhymustIhaveaname/fanslow-omen-2021. It can slow the speed of fans to 40% and 45%. Although not as slow as 30% I wanted, it is much quieter.

I am a user of en-100. I found that 0x34, 0x35 are the inputable fan rpm. Nbfc for windows does not work. I know it is a problem with the openhardwremonitor plugin.
