[Bug 462902] Re: Fan always running since karmic install

[Teras]

Same problem here too.

* DELL Studio 1557 - (Core i7 @1.60) 
* 2.6.31-19-generic #56-Ubuntu SMP x86_64 GNU/Linux

The laptop came with Windows 7 installed , and it was totally silent.
After I installed ubuntu, things became ...noisy AND hot :)

A fan is heard working all the time (very loudly) and the area around
mousepad tends to become very hot after some time (2 hours+)

I tried changing the CPU frequency and used some certain governors, such
as "ondemand", offered by the cpufreqd tool....but nothing changed
concerning the fan speed and noise.

Notes:
======

- I 've got the A02 BIOS version (10/06/2009) ...but I think it doesnt matter, people with A03 also faced same problem.
- also: 

$ cat /proc/acpi/fan/FAN0/state     
status:     on

$ cat /proc/acpi/fan/FAN1/state     
status:     off

$ cat /proc/acpi/thermal_zone/TZ00/temperature 
temperature:             27 C

$ cat /proc/acpi/thermal_zone/TZ01/temperature 
temperature:             55 C


I attach my lsmod.

ps: I was also  told that this could be an issue of DELL, since Windows
7 power management is set to "Balanced",  so in case of greater
workloads, the fans could then busy noisy too.

*The thing here though, is that the fan becomes being noisy since Grub
starts loading......

Thank you.
