Hi,
ich entschuldige mich sofort für double/tripple Posting-aber vielleicht finde ich hier Hilfe. Habe ein Acer Aspire One 756 mit Celeron 847 gekauft- tolles Gerät für den Preis. Der Lüfter ist sehr leise, aber habe Gefühl, dass er trotzdem unnötig dauernd läuft. Deswegen hätte ich gerne eine Lüftersteuerung. Da aber AO756 ziemlich neu ist, funktionieren hier keine bisher bekannte Lösungen (acerfand, acerhdf, fancontrol...). Ich habe meine Frage noch hier veröffentlicht:
fancontrol/acerfand/acer_ec.pl/acerhdf für Aspire One 756 (AO756)? ? System einrichten und verwalten ? Forum ? ubuntuusers.de
[xubuntu] fancontrol/acerfand/acer_ec.pl/acerhdf for Aspire One 756 (AO756)? - Ubuntu Forums

Falls es sich hier jemand gut mit Linux-Lüftersteuerung kennt-bitte um die Hilfe.
Derzeit versuche ich irgendwie die BIOS Version in acerfand einzutragen, aber es gelingt mir nicht:
Code: 
linux@linux:~$ sudo acerfand
/usr/local/bin/acerfand: Zeile 87: BIOS_VERSION_1.05=v1.05: Kommando nicht gefunden.
/usr/local/bin/acerfand: Zeile 132: Syntaxfehler beim unerwarteten Wort `"$BIOS_VERSION"'
/usr/local/bin/acerfand: Zeile 132: `case "$BIOS_VERSION" in'

D.h.-habe keine Ahnung wie man V1.05 im bash Skript eintragen lässt:
Code: 
BIOS_VERSION_3305="v0.3305"
BIOS_VERSION_3309="v0.3309"
BIOS_VERSION_3310="v0.3310"
BIOS_VERSION_105="v1.05"
BIOS_VERSION_05="v1.05"
BIOS_VERSION1_05="v1.05"

# Changelog:
# 0.07 - change fan-raw-state setting for 3309. may fix people's issues
#        i didn't have same issues but did find it repeatedly switching fan off unnecessarily
#        because it was misdetecting the fan state, and which was logging and keeping my hard drive alive.
# 0.06.1 - experimental limited release with different fan-off controls for 3309.
# 0.06 - getBiosVersion before reading acerfand.conf, to allow user to force version
# 0.05 - Regognise bios 3309 and autoselect as default
# 0.04 - Recognise bios 3305
# 0.03 - Recognise bios 3109
# 0.02 - Added support for recognising bios version and selecting ec reg values accordingly
# 0.01 - Initial version, no bios checking, works on <=v0.3114

Niemand?
Natürlich-wenn ich eintrage:
linux@linux:~$ sudo pwmconfig
[sudo] password for linux:
# pwmconfig revision 5857 (2010-08-22)
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.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

Da die "Linuxer" hier deutlich in der Minderheit sind, ist natürlich auch der Erfahrungsschatz zu deinem Thema wohl (noch) nicht gegeben!?

Du bist hier selbstverständlich richtig, aber wie du schon selbst bemerkt hast, tendieren die Aktivitäten in diesem Bereich gegen Null (etwas übertrieben).
