Heat problems with laptop running Ubuntu

[t341]

I have just installed Ubuntu 6.10, 2.6.17-11-generic kernel, on
a Compaq Presario v6000z laptop with no changes made to the
installation yet except for installing Nvidia drivers for the video
chipset. The temperatures are so high ( 58c core temperature,
74c gpu temperature idle) that I do not want to leave this laptop
running while trying to poke around with the settings right now.
The fan will go on for short periods once in a while but I need to
have more control over how the fans operate.
In the folder proc/scpi/thermal-zone/THERM there are a number
of configure files for cooling mode, temperature, polling, etc. but
there is no content to any of these files, they are empty.
Can someone help a new user configure Ubuntu for better heat
management?

I absolutely love running Ubuntu, I have been for a year now on my desktops. Unfortunately Ubuntu on every laptop I've tried sucks. Poor battery life, heat issues make it unbearable for travelers. I do have it as a dual boot on mine so when I'm docked I'll have no probs..

Actually I don't know if those are configurable, /proc is a virtual filesystem made up from the state of the current running kernel so none of those files are real. But even so, some of them are editable, you can run "echo newvalue > file" and if the file is indeed configurable it'll set whatever value it holds to the newvalue you gave it. But if those files are indeed empty it probably means that the ACPI implementation in your laptop's firmware sucks, have you looked to see if there's any updates for it?

Can it be C3 state problems with the processor by a chipset problem or misconfigured Bios ?(Cool and Quiet sometimes have to be disable to cool down your CPU...)
For Nvidia I know the drivers have to be tweaked to cool down the GPU for certain GPUs, but the problem seems to be ACPI.
ACPI in some Laptops are a problem because of the rerouting IRQs, try to disable Extended IRQs in the Bios ( This will leave a real IRQ 9, 10 or 11 for ACPI ), enabling ACPI with the kernel. The problem is to reinstall...

I get better life and have had many less problems with my Dell D810.
