작고 얇은...
그런데... 팬소리가 좀 거슬려요.
이번에는 팬속도를 조절해야겠다 마음먹었어요.

여기 포스팅을 보고 그대로 따라했습니다.
전 이미 sensors 설치를 해놓은 터라
일부만 따라했어요.
순서는
1. 센서라이브러리(lm_sensors)를 설치합니다.
2. pwmconfig 실행합니다.
3. fancontrol을 실행합니다.
4. 시스템시작시에 자동으로 실행되게 합니다.
2번에서 헤매게 되는데요.
설명은 본문아래에서 다시 하겠습니다.
1. Detecting sensors
Before you can read out any temperature values and change the fanspeed accordingly, you have to your operating system which sensors you are actually using.
Fortunately, there is a small program that does the job for you.
Fortunately, there is a small program that does the job for you.
sensors-detect comes with lm_sensors, so we make sure, the latest version of lm_sensors is installedyum install lm_sensors |
before we start
sensors-detect
Pretty cool, huh? Make sure, the
lm_sensors daemon gets started automaticallychkconfig lm_sensors on |
2. Configuring sensors and fans
The
fancontrol script can automatically respond to temperature changes of your system by changing fanspeeds. Basically, we have to map one temp-sensor to one fan controller. fancontrol‘s config-file can be easily manipulated with pwmconfig. The program is quite self-explaining; It can even create detailed correlation with gnuplot automatically.
If you later want to change some values manually, you can also edit
/etc/fancontrol without pwmconfigusing your favourite editor. See also fancontrol manpage.3. Automatically starting fancontrol
Unfortunately there comes no init script with
fancontrol in Fedora or CentOS. So we have to ensure, fancontrol gets started automatically during boot. The easiest way is to put fancontrol into rc.local# echo 'fancontrol &' >> /etc/rc.local |
Sending the process to background with a subsequent ampersand is crucial. Otherwise the boot process may hang.
You can of course write your own
You can of course write your own
fancontrol init script if you want to do the full Sys V style init stuff.
Restart the computer and enjoy silence!
아래는 pwmconfig를 실행했을 때 볼 수 있습니다.
[root@localhost ~]# pwmconfig
# pwmconfig revision $Revision$ ($Date$)
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/device is it8772
Found the following PWM controls:
hwmon2/device/pwm1 current value: 0
hwmon2/device/pwm2 current value: 150
hwmon2/device/pwm3 current value: 76
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon2/device/fan1_input current speed: 0 ... skipping!
hwmon2/device/fan2_input current speed: 6683 RPM
hwmon2/device/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:(첫번째 팬이 멈추고 온도가 올라갈 수 있다 원하지 않으면 컨트롤 씨, 엔터는 시작!)

no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon2/device/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,

Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
