Ventilateur Bruyant, Réduire sa vitesse
Bonjour à tous,
je viens de recevoir un serveur DELL PowerEdge 860.
Il possède 2 énormes ventilateurs qui font beaucoup de bruit (un avion au décollage).
Le processeur, au toucher est quasi-froid (tout juste tiède).
Je cherche donc à réduire fortement la vitesse de rotation de ces ventilateurs.
J'ai donc installé lm-sensors.
Executé sensors-detect et chargé ces modules :
modprobe i2c-i801
modprobe lm85
modprobe eepromAprès, je fais un sensors et là :
sensors
lm85-i2c-0-2e
Adapter: SMBus I801 adapter at 08c0
V1.5: +0.00 V (min = +0.00 V, max = +3.32 V)
VCore: +0.00 V (min = +0.00 V, max = +2.99 V)
V3.3: +0.00 V (min = +0.00 V, max = +4.38 V)
V5: +0.00 V (min = +0.00 V, max = +6.64 V)
V12: +0.00 V (min = +0.00 V, max = +15.94 V)
CPU_Fan: 0 RPM (min = 0 RPM) ALARM
fan2: 0 RPM (min = 0 RPM) ALARM
fan3: 0 RPM (min = 0 RPM) ALARM
fan4: 0 RPM (min = 0 RPM) ALARM
CPU Temp: +0°C (low = -127°C, high = +127°C)
Board Temp:
+0°C (low = -127°C, high = +127°C)
Remote Temp:
+0°C (low = -127°C, high = +127°C)
CPU_PWM: 255
Fan2_PWM: 255
Fan3_PWM: 255
vid: +2.050 V (VRM Version 8.2)Donc, ça ne fonctionne pas.
Il trouve bien les ventilateurs mais n'arrive pas à les sonder.
Ceux-ci ont pourtant bien 3 fils.
Enfin, encore plus étrange, voilà ce que renvoie un pwmconfig
Found the following PWM controls:
0-002e/pwm1
/usr/sbin/pwmconfig: line 102: 0-002e/pwm1_enable: Permission non accordée
0-002e/pwm2
/usr/sbin/pwmconfig: line 102: 0-002e/pwm2_enable: Permission non accordée
0-002e/pwm3
/usr/sbin/pwmconfig: line 102: 0-002e/pwm3_enable: Permission non accordée
Found the following fan sensors:
0-002e/fan1_input current speed: 0 ... skipping!
0-002e/fan2_input current speed: 0 ... skipping!
0-002e/fan3_input current speed: 0 ... skipping!
0-002e/fan4_input current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.Donc, là encore ça ne tourne pas rond.
(il va sans dire que j'ai fait un chmod sur les pwm*, mais que ça ne change rien).
Si ça vous aide, voilà le compte rendu d'un lshw complet :

Re : Ventilateur Bruyant, Réduire sa vitesse
L'accès à la vitesse des ventilos, ou mieux au réglage de celle-ci, dépend du modèle de CM. Chez moi, la CM ne permettait pas de modifier la vitesse du ventilo processeur (elle n'est pas sur cette liste).
Une solution hardware si tu as une petite pince coupante et des cables d'alim non-utilisés : brancher les ventilos sur du 5V (fil rouge) au lieu de l'habituel 12V (fil jaune).
Il faut alors bien contrôler que le débit d'air obtenu soit suffisant, et que le processeur en pleine charge ne monte pas trop haut en température. Si le 5V est trop juste, on peut également obtenir du 7V en branchant 1 rouge et 1 jaune. (12V - 5V = 7V)
Attention aux faux-contacts
