AMD mobile CPU problem: temperature too high

Newbie here.
I bought and AMD based laptop.
I installed archlinux but I encountered a problem.

First of all: specs.
AMD Turion II P540
AMD/ATI 5470

on windows 7, temperatures are 45 C / 58 C (idle/load)

On my linux distro (arch 64bit, kernel .38) temperatures are stuck @ 60 C in idle!
Temperatures were measured by lm_sensors.
Ubuntu confirms the issue.

My archlinux setup is new; I added these modules after installing cpufrequtils:
powernow-k8 for cpu scaling
ondemand governor enabled and it is the default governor

cpu scaling is working.

No proprietary video driver installed. Using xf86-video-ati/radeon

My suppositions:
a) undervolting not supported/bug/whateverelse????
b) proprietary drivers needed?? maybe the high thermal power is produced by GPU and not from CPU???

Where is my mistake?

At first I would try the proprietary AMD driver for the graphics-card. Is the CPU fan running at all?

oh yess, there is only one fan (it's a laptop).
Today, in linux, the laptop reached and maintained 62 C. It was VERY hot.
Fan @ max

I installed proprietary drivers.
Kernel module loaded by
modprobe fglrx
but anything changes.

Now I try with the last ubuntu LTS. Maybe I'm too noob to use n configure archlinux.
