On HP laptops (especially non-gaming models), the fan curve is hardcoded in= side the Embedded Controller (EC) firmware and cannot be controlled directly by = the OS. Since the ACPI tables do not expose active cooling trip points, we cann= ot change them via sysfs. You should ask HP to release an updated firmware: on my side I think I've d= one everything in my power. --=20 You may reply to this email to add a comment.
