fan control dell studio 15

hi,
I got my dell studio 15 yesterday. Bootin into vista the fan was fine, booting in archlinux the fan is on constantly at almost max speed.. I8k hangs my machine so that isn't an option. Sensors-detect only detects coretemp. Pwmconfig says there are no detected modules. (I have coretemp loaded)

Is there a solution? Is my hardware to new for linux?

Re: fan control dell studio 15

alright so I got i8k to work. The module is loaded using force and i8kmon stops my fan. (after a long while it goes in full speed to cool the cpu for a short time and then back to zero)
Only problem now is that my whole laptop hangs when i8kmon is running. It doesn't respond to keyboard presses nor mouse control. (only once every 20 seconds does it respond.) I even have to wait for the magic sysrq key to be registered. (to reboot the syem and sync ,...)

Any possible fixes? Does it sound familiar to some people?

Re: fan control dell studio 15

The i8k kernel module gave me a whole lot of trouble, sometimes it wouldn't load, sometimes it messes my bootup screen entirely, sometimes it hangs the whole system... So I've disabled it, acpid works just fine on my vostro 1310...

Re: fan control dell studio 15

you mean you didn't have to do anything but load acpid? Or did you wrote specific acpi events? (like when temp gets above .. do ...)
My fan just starts blasting all the way up (from the dell boot screen) to the point where i8kmon kicks in,

Re: fan control dell studio 15

It may have nothing to do with your problem, but if you are using KDE4 and have the calendar widget on your desktop, this may cause your fan to be at maximum. Some bug in the widget, I don't know. At least this was the problem for me in KDEmod, I'm not sure if this happens also in vanilla KDE4.

So probably nothing to do with your situation, but I thought I just throw it in, in case you actually use that.

Re: fan control dell studio 15

no I wasn't using kde4 but thanks anyway ;-). It is all the way from the bios to the command line not running any app whatsoever.(offcourse it stays on the whole time i use linux)
I noticed reinstalling that vista the same problem is occuring but after installing the dell drivers the fans start to behave great. This means that the bios is crap at controlling the fan and that linux doesn't offer an appropriate driver yet.
Biting my nails till the next great update I guess.
