Re: Latitude C400 Overheating+Slowdown under Debian Etch
- Ok, thanks, so it seems that the fan is broken.
Meanwhile I had reduced in BIOS the AC mode from
maximal performance to maximum battery and I work
on 750MHz instead of 1GHz even on AC. Running this
mode I get maximum on heavy long loads to 65-68C
So it do not creates problems but it is 25% peformance
If I was able to adjust the CPU frequency according
to temperature thresholds:
1000MHz - 60 normal work low temperatures
750MHz 60 - 80 reduce under loads
185MHz 80 + critical temperatures
But cpufreq-set do not work and I /proc/acpi/
there is no support for changing CPU freq.

I had found the solution for clock control according
to the temperature of the CPU.
I had to load following modules:
and then I had installed cpufreqd that had given me the solution
I just adjusted a little temperature ranges in /erc/cpufreqd.conf
and thats it. Even at heavy long loads I get maximum to 75C and
the clock is reduced to 750MHz and normally it works on 1GHz at
temperatures of about 55C.
