Fan very loud in Ubuntu 12.10

Solution 1:

I had this after installation, but it went back to normal after doing a re-boot. That was 3 days ago and it has been ok since then.

Solution 2:

I have a similar problem in Xubuntu 11.10 which has developed excessive fan noise in the last few months. Looking at the processes tab in Sys monitor, Firefox does appear to be using a lot of CPU % when doing things like switching/opening tabs, even scrolling with 3 tabs open uses 20%

For me it has only occured in the last few months, previous to that it was fine so maybe it is related to Firefox specifically?

Solution 3:

I had the same problem. I'm not sure if this is still a problem in the kernel 3+, but my fan behaves now more or less as under Windows 7. I followed the advice for a fix here (webupd8.org).

Solution 4:

you should consider installing jupiter, since this fixed my blazing fans.

you can select power modes with it, and it's very easy to control.
I always install this on my laptops, and set it to power on demand(personal opinion).

open terminal and do this.

add the repository

sudo add-apt-repository ppa:webupd8team/jupiter

update

sudo apt-get update

install jupiter

sudo apt-get install jupiter

and to other people reading this and are using an Asus EEPC netbook, install this asswell

sudo apt-get install jupiter-support-eee

Have a nice day :)

You might try to determine which fan is having the problem.

I have a Dell Dimension 9200 with an NVidia graphics card (GeForce 7900 GS) and was having the same issue. It turned out, it was the graphics card fan that was the underlying noise maker. I was able to fix this by using the proprietary NVidia driver instead of the Nouveau driver.

I changed using the Software Center: 1) Open Software Center 2) Select Edit | Software Sources 3) Select the Additional Drivers tab 4) Choose Using NVIDIA binary Xorg driver, kernel module and VDPAU library from nvidia-304-updates (proprietary) 5) Press the Apply Changes button 6) Quit the dialog, reboot, and viola, no more fan noise.

I used the instructions found here as my guide for changing the drivers.
