Unhappy pavilion cpu fan wont stop...


hi people

i'm desperate, hope you can help me

I'm using Linux Slackware (current), Kernel 2.6.14.3 on HP Pavilion ze4274s, but I have never noticed that cpu fan work so much.

For example, usually when I run back into console and doing nothing the fan should switch it off, and tempreature should be less, but on a contrary fan is still on, and the temprature is only 2-3C lower.
The Cpu - temprature is always between 55-63. From 52-62C is fan at "speed one", and from 63 is "speed two" that sounds like a jet taking off.
Is there any posible way to change value of fan switching on, for example to make it switch on first at 58C.

I have installed omnibook module hoping I could switch fan off, but I get message when omnibook module is starting
omnibook: Fan status monitor and control is unsupported on this machine.
omnibook: Fan policy is unsupported on this machine.

I have tried so many things to keep my cpu-fan quiet, but without any success.

I don't know what I'm doing wrong, is there some problems whit this kernel version, or is something else.

For more information about my laptop (and kernel config files) please visit

I would be very thankful for any help

Do you have ACPI and its child features enabled in the kernel? One of them is for fan control. That's what I use (without any omnibook extras) on my Pavilion ze4315 and it works.

Yes there are all enabled.
Could you switch your cpu-fan off, or you can see only is it on or off?
Which version of kernel du you have?

My config is very similar to yours, except for some of the options at the bottom of the list. Here is mine. I just installed 2.6.15.4, importing the config from my 2.6.14.1, of which I didn't change anything.

The ASUS and Toshiba options only apply to laptops of those brands. The IBM option says it adds support for Fn-Fx key combinations, which is why I enable it as a module (It works on mine). I haven't needed the timer and the container doesn't sound like anything that applies.

To answer your question, I do notice when the fan speeds up and slows down. It's up for a while when doing things like loading apps or compiling source - anything that puts load on the cpu. When it's not busy (not compiling, not working with a file, not playing games) it calms down to a hum.

A thought just now, is the acpi daemon enabled? Check /etc/rc.d and see if rc.acpid is executable.

acpid is started and executable.
I've just downloaded 2.6.15.5 and made changes in config and made it identical to yours, though I don't thing that would change a thing.

Is it posible that a fan-thing is not supported for a mobile celeron?

could you please send me your config to email, maybe there are some other things that need to be changed?

my mail: nijebitno (at) gmx . net

thanks

still can get control over cpu-fan. Compilied new 2.6.15.5 and everything is pretty much the same.

but finally, thanks to God, I found whats wrong!

Seems to be some bug in a X (probably latest 6.9.0).

When I reboot the machine everything works fine until I get in the X (tested kde, xfce).
Temperature before entering X is not much then 53C mostly 45C, and cpu-fan works really nice.
After starting X temperature gets to 55C and more.
Now something very interesting!
After exiting X and returning to console temprature stays at 55C, cpu-fan is always on, and temperature dont get lower than that. But as far as I know should be lower.

Checking processes before starting X and after returning to console shows nothing, meens theres no any new processes running. Everything seems normal, but isn't.

Million dollar question is: how to know what thake cpu power and make temperature not getting under 55C?

dmesg shows nothing, ps shows nothing, top...

desperately need some really good advice

thanks
