The RPM reading actually works perfectly fine! There is just a slight normal delay in the EC updating the value after the fans spin up. I re-tested it, and the RPM values are be= ing reported correctly. Also, writing 1 to `pwm1_enable` works flawlessly, and adjusting `pwm1` fro= m 0 to 255 scales the fan speed smoothly and exactly as expected. Thank you so much for your fast and incredibly effective help! --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
