Thanks for answering, good to see that i am not alone!
I already disabled this option and it actually didn't changed much.

I have a Probook 4510s and a similar problem.
One thing you can try doing is going into your bios and disabling the
"fans always on while on AC power" option..did not work for me, but
could work for you :)

Hello folks.
I 've been on lesswatts.org <http://lesswatts.org>, trying to fix
an issue that makes my fans always on (hp probook 4530s / i5 /
ubuntu 11.10).
I am not sure about what is going on, if my power consumption is
ok, and it's my fan control that is bad, or if it is the opposite ...
The first entries of my powertop overview list :
Power est. Usage Events/s Category Description
3.52 W 100,0% Device Radio
device: ath9k
2.38 W 100,0% Device Audio codec
hwC0D3: Intel
651 mW 100,0% Device Display
backlight
651 mW 100,0% Device Display

651 mW 100,0% Device Display

17.3 mW 50,8 ms/s 0,0 Process
/usr/lib/thunderbird-7.0.1/thunderbird-bin
13.7 mW 40,3 ms/s 0,0 kWork
input_polled_device_work
12.8 mW 37,6 ms/s 0,0 Process compiz
I did not managed to activate the power_saving mode of the wifi
radio, following the tutorial.
Also, i was wondering how this intel codec could consume so much
...? what should i do with it ?
After googling my problem of fans a bit of time, i've read that
there has been a linux kernel regression regarding these aspects
of power consumption... i find it hard to accept that there is no
other solution that waiting for fixes & I would like to understand
better those aspects.
What do you think about that ?
thanks,
