HP Pavillon DV7 7-2670QM fan control???


I have a HP Pavillon DV7
which has cuadcore Intel(R) Core™ i7-2670QM CPU @ 2.20GHz
On win7 the fan stops and almost never runs if you don’t use cpu power.
On opensuse 12.1 the fan always run full…

How can I control this?
I have loaded acpi_cpufreq but there is no /proc/acpi entry for fan :frowning:

Thanks a lot


I have read in an other thread a similar problem.
It’s right in OS 11.4 the fan works right, in 12.1 the fan is everytime on.
OS 11.4 and 12.1 have the same dmesg output i.e. that fan is controlled

but on OS 12.1 there is no /proc/acpi/processor directory
IN OS 11.4 for every CPU there is an

What I also noticed is that it seems that default installation installs both modules radeon an i915
but it seems that the i915 is active not radeon. Could this be the problem of heating and therefore
the fan is always on?
How can I activate the radeon driver?
