root@host:~# pwmconfig File /var/run/fancontrol.pid exists. This typically means that the fancontrol deamon is running. You should stop it before running pwmconfig. If you are certain that fancontrol is not running, then you can delete /var/run/fancontrol.pid manually. root@host:~# service Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ] root@host:~# service fancontrol stop root@host:~# pwmconfig # pwmconfig revision 6243 (2014-03-20) This program will search your sensors for pulse width modulation (pwm) controls, and test each one to see if it controls a fan on your motherboard. Note that many motherboards do not have pwm circuitry installed, even if your sensor chip supports pwm. We will attempt to briefly stop each fan using the pwm controls. The program will attempt to restore each fan to full speed after testing. However, it is ** very important ** that you physically verify that the fans have been to full speed after the program has completed. Found the following devices: hwmon0 is acpitz hwmon1 is coretemp hwmon2 is nct6106 Found the following PWM controls: hwmon2/pwm1 current value: 127 hwmon2/pwm2 current value: 255 Giving the fans some time to reach full speed... Found the following fan sensors: hwmon2/fan1_input current speed: 0 ... skipping! hwmon2/fan2_input current speed: 2749 RPM hwmon2/fan3_input current speed: 0 ... skipping! Warning!!! This program will stop your fans, one at a time, for approximately 5 seconds each!!! This may cause your processor temperature to rise!!! If you do not want to do this hit control-C now!!! Hit return to continue: Testing pwm control hwmon2/pwm1 ... hwmon2/fan2_input ... speed was 2749 now 2772 no correlation No correlations were detected. There is either no fan connected to the output of hwmon2/pwm1, or the connected fan has no rpm-signal connected to one of the tested fan sensors. (Note: not all motherboards have the pwm outputs connected to the fan connectors, check out the hardware database on http://www.almico.com/forumindex.php) Did you see/hear a fan stopping during the above test (n)?#此时应该是测了风扇1，并没有听见停止，所以选n Testing pwm control hwmon2/pwm2 ... hwmon2/fan2_input ... speed was 2749 now 1205 It appears that fan hwmon2/fan2_input is controlled by pwm hwmon2/pwm2 Would you like to generate a detailed correlation (y)?
