###################################################################### ## thinkfan 0.9 example config file ## ================================ ## ## ATTENTION: There is only very basic sanity checking on the configuration. ## That means you can set your temperature limits as insane as you like. You ## can do anything stupid, e.g. turn off your fan when your CPU reaches 70°C. ## ## That's why this program is called thinkfan: You gotta think for yourself. ## ####################################################################### ## ## This file shows how to use sensor-specific temperature limits. ## First of all, you need to specify temperature inputs. On a Thinkpad, you can ## just use: ## tp_thermal /proc/acpi/ibm/thermal # provides us with 16 temperature inputs ## ## On other systems, you have to specify a file in /sys/class/hwmon for each ## sensor you want to use. They are numbered in their order of appearance. ## For example: # # hwmon /sys/class/hwmon5/temp2_input #1 # hwmon /sys/class/hwmon0/device/temp3_input #2 # ## If you want to read temperatures directly from the hard disk, thinkfan needs ## to be compiled with -DUSE_ATASMART. Then you can do: # # atasmart /dev/sda #3 # ... # ## You can have as many temperature inputs as you like. You should at get the ## temperature from the CPU, the GPU and the hard disk. # # ## Next we specify the fan we want to use. On a Thinkpad, this is: # tp_fan /proc/acpi/ibm/fan # ## On anything other than a Thinkpad you'll probably use some PWM control file ## in /sys/class/hwmon. Remember that fan levels range from 0 to 255 and that ## they're just a number, not including the word "level" as seen below. ## A sysfs fan would be specified like this: # # pwm_fan /sys/class/hwmon/hwmon2/device/pwm1 # ## But remember you can only have one fan. # ## Then you need to specify the temperature limits for each of the sensors. ## A dot means that the corresponding sensor should be ignored. The length of the ## UPPER and LOWER limits must be the same as the number of temperatures. In this ## example, /proc/acpi/ibm/thermal contains 16 sensors (on older thinkpads, ## there may be only 8), some of which are unused (hence the dots). ## A sysfs temperature input always contains only one sensor, so if you specify ## 5 sysfs files above, the length of your limits must be 5, too. # ## I've come up with these preliminary settings for my Thinkpad T61p. They probably ## don't make sense for anything else, so you most definitely have to work ## something out for yourself. # { "level 0" # the fan level # ^-------^ This works for /proc/acpi/ibm/thermal. # for a PWM fan in /sys/class/hwmon it would have to be just # 0 or "0". # # Sensor count: # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 # ============================================== (0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0) # LOWER limit (54 42 42 54 42 . 42 . 42 46 54 . . . . .) # UPPER limit } { "level 1" # ^-------^ For a PWM fan you may have to use something around 30 to get the # same speed.
