Dell Vostro fan keeps turning on every 10-15 seconds

Asked by Parvez Halim on 2012-03-01

Hi, I'm a newbie. I just got a Dell Vostro 3550 and installed Ubuntu 11.10. The problem is that the fan keeps turning on every 10-15 seconds for about 5 seconds. I am not doing anything taxing like encoding video. I'm not even watching a flash video. No matter what I do the same thing happens. It's driving me crazy!

Please help!

What is the output of:

lsb_release -a; uname -a

Also do you have the latest BIOS? If you log in and run no apps does the fan still run as you describe?

the output I get is:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 11.10
Release: 11.10
Codename: oneiric
Linux parvez-Vostro-3350 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux

As soon as I'm on the Ubuntu desktop it starts.

I used the command sudo dmidecode -s bios-version (no idea if this is correct. I just googled it) to get the bios version. The answer was A07.

Thanks for the help.

Seems to be the most recent. Are there any bugs reported?

Can you help with this problem?
