 Posted: Wed Jun 28, 2006 10:58 pm Post subject: fan is not working properly |
 |
|
hi,
this summer is very hot here. My laptop has and intel centrino sonoma (1.6ghz, min speed 800mhz), that is quite cold on windows, where the fan often is on.
On gentoo, the fan is active very seldom (i can say NEVER) at his full speed. Imagine that you are compiling for hours, with governor powersave, and the temperature is about 86-90°C (186°-194° F) or more (ambient: 32°C, 89°F), is this normal?
i agree that probably fan is bios-controlled.
maybe the temperature from /proc/acpi/thermal_zone/THRM/temperature is wrong?
now, for example, during a compilation with powersave governor (800mhz) is 62°C (143°F)
laptop is sony vaio fs115b
thanks for helping |

That definitely does not sound normal. Do you have any module to control fan speeds? I have a dell laptop for which I use i8k. I can make it auto or manual using a gkrellm plugin. I usually leave it in auto and the fan comes on when the temp goes above 55C. Even on full load the max temp it reaches is about 75C and comes back down once the load is down.

do you mean if thermal and fan is enable in kernel? yes, they are
(performance governor, no activity no compilation, only web browsing)
also this can help:
| Code: |
localhost THRM # cat trip_points
critical (S5): 105 C
passive: 95 C: tc1=1 tc2=5 tsp=10 devices=0xc18d8800
localhost THRM # cat cooling_mode
<setting not supported>
cooling mode: passive
localhost THRM # cat temperature
temperature: 71 C
cpufrequtils 001: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: centrino
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: ondemand, powersave, performance
current policy: frequency should be within 800 MHz and 1.60 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1.60 GHz (asserted by call to hardware).

/proc/acpi/fan is empty.
[edit]
with the latest version of iasl available on portage, my DSDT shows no errors.
previous version give me errors.
wtf? |

I apologize in advance if I misunderstood your post, but are you saying that you are trying to use a computer (any computer) when the surrounding air temperature is 89°F? Is your laptop even warranted to work in those conditions? Check the manual to see what the acceptable range of operating temperatures is.

| and pls use "cpufreq-set -g conservative", also check kernel config for Dothan acpi tables in cpu governors. There's something called Vaio extras in ACPI config I think. |

yes, 32C°,(see http://www.wbuf.noaa.gov/tempfc.htm ) this is italy this summer 
so, what is your ambient working T?
so i cannot use my laptop in africa, for example

why should i use conservative, i think powersave is safer for temperature (never above 800mhz)
| Code: |
localhost gremo # cat /usr/src/linux/.config | grep TABLE
CONFIG_CPU_FREQ_TABLE=y
CONFIG_X86_SPEEDSTEP_CENTRINO_TABLE=y

No, you're NOT using powersave until you set it as a governor. See that info of yours?
| Code: | current policy: frequency should be within 800 MHz and 1.60 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1.60 GHz (asserted by call to hardware). |
And you're missing some kernel options, like:
CONFIG_X86_SPEEDSTEP_CENTRINO_BUILTIN_SONOMA=y |

yes, i can set powersave governor

i don't have this option, what kernel you are using? |

is that available and masked on portage (sys-kernel/mm-sources)?
is there a guide to better configure this kernel (i always used gentoo-sources)?
thanks, i'll try it, maybe i'll solve my problem |
