This creates a stability area of two degrees, which seems to - be enough. Please let me know if you have problem with the - resulting overall behavior. + See the man page for details about the algorithm, arguments and + configuration file. * NOTES - I wrote this daemon for my personal usage on a X61s, and using it - may damage your hardware. - On Thinkpads you have to allow the module thinkpad_acpi to set the fan speed, which is not allowed by default in Debian. To do so, you have to have a file /etc/modprobe.d/thinkpad_acpi.modprobe
