Inspiron 6000 CPU Fan Uses One Speed

Chryzmo · 11-16-2005, 05:52 PM

Hello all,

I have an Inspiron 6000 and I can hear the fan spinning, but it seems it only has one speed. In Windows the fan will get a lot louder when I'm doing CPU intensive work. I have yet to have my laptop lock up or restart on me, but this is my only computer and I just want to make sure I'm not risking it over-heating.

Is the fan only using one speed because Linux is keeping the CPU cooler than Windows does or do I need to add different fan profiles or something similar to what I did got cpufreqd?

Also, at one temperature should I start being concerned with it over heating? When idling it tends to stayaround 38-40C. I was just compiling and kernel and downloading something and it went up to 57-59C.

Thanks,
Chryzmo

Did you enable this;

Code:

#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=y
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m

# CONFIG_X86_CPUFREQ_NFORCE2 is not set
# CONFIG_X86_LONGRUN is not set
# CONFIG_X86_LONGHAUL is not set

Thats for mine yours will be different.

You should use a cpu clock speed controlling daemon, such as "cpufreqd" or "powernowd". Make sure you load the necessary modules. You can use my page as a reference:
