J'utilise ArchLinux sur un HP Pavilion dv9000t qui a des problèmes de surchauffe. J'ai fait tout ce que je pouvais pour obtenir un meilleur flux d'air dans le portable et mettre une meilleure pâte thermique mais il y a toujours un problème:
le ventilateur cesse de tourner lorsque la température du CPU est basse (même si la température du GPU est élevée, ce qui est problématique).
J'ai découvert que je pouvais faire fonctionner le ventilateur en lançant des commandes de traitement lourdes (comme la yes
commande). Cependant, ce n'est pas une solution car j'ai besoin d'arrêter cette commande lorsque le CPU devient trop chaud et de la relancer lorsque le ventilateur s'arrête (pour que le GPU ne chauffe pas).
J'ai essayé de contrôler le ventilateur en utilisant ce wiki , mais quand je cours pwmconfig
, j'obtiens cette erreur:
/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed
Savez-vous que puis-je faire pour que le ventilateur tourne toujours?

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Module cpuid loaded successfully.
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
AMD Family 12h and 14h thermal sensors... No
AMD Family 15h thermal sensors... No
AMD Family 15h power sensors... No
AMD Family 16h power sensors... No
Intel digital thermal sensor... Success!
(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801H ICH8
Module i2c-dev loaded successfully.
Next adapter: nouveau-0000:01:00.0-0 (i2c-0)
Do you want to scan it? (yes/NO/selectively):
Next adapter: nouveau-0000:01:00.0-1 (i2c-1)
Do you want to scan it? (yes/NO/selectively):
Next adapter: nouveau-0000:01:00.0-2 (i2c-2)
Do you want to scan it? (yes/NO/selectively):
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
Do you want to overwrite /etc/conf.d/lm_sensors? (YES/no):
Unloading i2c-dev... OK
Unloading cpuid... OK
Le fichier /etc/conf.d/lm_sensors
contient:
HWMON_MODULES="coretemp"
Et le fichier /etc/modules-load.d/lm_sensors.conf
contient:
coretemp
acpi-cpufreq
La commande sensors
génère ceci:

(emerg = +115.0°C, hyst = +5.0°C)
sensors-detect
?
sensors-detect
et j'ai ajouté sa sortie au message. Pour la yes
commande, j'ai pris un peu de temps pour découvrir qu'il vaut mieux augmenter la température du CPU que quatre simultanément grep
sur tout le disque dur (je ne sais pas pourquoi cela demande beaucoup de CPU, cependant).
yes
commande soit lourde en termes de CPU. A part ça, bonne question :)
