I've recently updated my ubuntu from 12.10 to 13.04 and since then the fan seems to have been stuck to 100%. It's unbearably noisy.
I've browsed through quite a lot of discussion whitout success.
I've installed tlp and it seems that my CPU is about 37°C, so I'm not sure if the problem come from an overheat or from a "fan management speed".
I've tried to get a newer version of the kernel (3.9), no change.
I've tried to use the kernel version I had with ubuntu 12.10 (3.5), no change neither
When I tried to boot on windows 7, same problem.
Actually, even if I stay on the grub menu for a few seconds, my fan goes from what used to be normal to full speed.
So maybe the problem comes from more basic stuff.
My configuration :
System = Medion E6217 (a laptop)BIOS = 202
Release = Ubuntu 13.04
Kernel = 3.9.0-030900-generic i686
Graphics = intel i915 (integrated)
I can provide other informations if you need.
Thanks for your help =/
Edit : I don't believe the problem could be from there, but here is some boot-info : http://paste.ubuntu.com/5629995/
