ファンコントロールソフトacerhdf
要点
- 熱いのにファンが回らない
- ファンコントロールソフトを設定してみよう
- いろいろやったけれどファンが回らない
- ファンが故障しているんだろう．諦める
メモ
acerhdf is a tool to monitor and control the fan of the popular acer aspire one netbook.
http://www.piie.net/index.php?section=acerhdf
it is included in mainline kernel since 2.6.31. but on this page you can get my current local development state, which is going to be merged into mainline in the future.
!!! use it at your own risk !!! no acer d150 and d250 support !!!
ファンコントロールモジュールの追加に成功しました。
AspireOneでubuntuを動作させているときに
今まで、背面というかウラ面というか、ファンのコントロールがされず、いつでも最大。

ガンガンに回っていました。
私の場合は，どんな場合でもファンがガンガン回らない感じ．

acerhdf - A kernelmodule which monitors the temperature
of the aspire one netbook, turns on/off the fan
as soon as the upper/lower threshold is reached.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0.0: VERY SHORT REFERENCE
install: make && make install
load module: modprobe acerhdf interval=10 fanon=67000 fanoff=62000 kernelmode=1
read temperature: cat /sys/class/thermal/thermal_zone0/temp
change parameter: echo 50000 > /sys/module/acerhdf/parameters/fanoff
1.0: INSTALL
1.1: DISTRIBUTION
Ensure you've installed everything to build a kernelmodule. For debian you
need at least to do: 'apt-get install build-essentials linux-kernel-headers'
1.2: ACERHDF
Obtain the source of the latest version from http://piie.net/?section=acerhdf
Untar the sources: 'tar xfvz acerhdf_kmod-<version>.tar.gz'
Compile: 'cd acerhdf_kmod && make'
Install: 'sudo make install'
1.3: AUTOSTART FAN CONTROL
To automatically start the fan control you can do:
'echo "options acerhdf kernelmode=1" | sudo tee /etc/modprobe.d/acerhdf.conf'
2.0: USAGE
2.1: LOADING THE MODULE
To load the module into the kernel type: 'modprobe acerhdf'
If you want let this happen automatically on system boot-up, add the module
acerhdf to your list of autoloaded modules. (ask google how this works for
your distribution)
2.2: CHECK
Launch the command 'dmesg|grep acerhdf' and read the messages printed out.
2.3: READING THE TEMPERATURE
The current temperature can be read by:
'cat /sys/class/thermal/thermal_zone0/temp'
2.4: MONITORING / CONTROLLING THE FAN
The fan can be monitored via:
'cat /sys/class/thermal/thermal_zone0/cdev0/cur_state'
ATTENTION: setting the fan state manually can damage your hardware!
To change the state manually you must first switch to user mode (see 2.5),
then following commands will change the state:
ON: 'echo 1 > /sys/class/thermal/thermal_zone0/cdev0/cur_state'
OFF: 'echo 0 > /sys/class/thermal/thermal_zone0/cdev0/cur_state'
2.5: ENABLING / DISABLING THE FAN CONTROL
enabled: acerhdf controls the fan automatically depending on the temperature
and the temperature thresholds (see 2.6).
disabled: acerhdf offers only the interface for reading the temperature and
setting the state of the fan. A userspace program must take care about
changing the fan state.
You can switch on the fan control via:
'echo enabled -n > /sys/class/thermal/thermal_zone0/mode'
To switch the fan control off:
'echo disabled -n > /sys/class/thermal/thermal_zone0/mode'
2.6: CONFIGURATION / PARAMETERS
acerhdf has following parameters:
o interval=10 - The interval in seconds, in which the temperature should be
checked in kernel mode. (default=10)
o fanon=67000 - The temperature in Celsius above the fan should be switched on.
(default=67000)
o fanoff=62 - The temperature in Celsuis below the fan should be switched
off. (default=62000)
o verbose=0 - Print out verbose messages to dmesg. (default=0)
o kernelmode=0 - enable the fan control after loading (default=0)
o force_bios="" - For testing purposes, see below.
o force_product="" - For testing purposes, see below.
Those parameters can be set when loading the module. E.g:
'modprobe acerhdf interval=5 fanon=65000 fanoff=60000 kernelmode=1'
You can add them to '/etc/modprobe.conf', so that they are automatically
applied, when the module is loaded. The line in modprobe.conf can look like
this:
'options acerhdf interval=5 fanon=65000 fanoff=60000'
Additionally every parameter (besides force_bios and force_product) can also
be read and written by accessing it via cat'ing or echo'ing the specific file in
/sys/module/acerhdf/parameters/*
Example:
'cat /sys/module/acerhdf/parameters/interval' to read the interval setting.
'echo 50000 > /sys/module/acerhdf/parameters/fanoff' to change the fanoff
setting.
3.0: TESTING UNSUPPORTED HARDWARE
!!!! ATTENTION !!!!
This could harm your hardware if you do not know what you are doing!
If you have hardware / bios which isn't officially supported by acerhdf, but
you are sure it should work, you can try to load the module by:
'modprobe acerhdf force_bios="v0.3305" force_product="AOA150"' or any other
bios version defined in source of acerhdf. The force_bios parameter will cause
acerhdf to omit the hardware and bios check and to pretend the chosen bios
version is available.
-> acerhdf will be started in user mode.
Before switching to kernel mode (see 2.5) test if the temperature and the fan
can be correctly accessed (see 2.4)
IMPORTANT: if you get your hardware / bios working with this parameter,
report it to peter (a) piie.net then it will get into the list of supported
devices.
