I've got Sony Vaio laptop and my fan is on all the time, though the temperature on the video-adapter is always over 60°С.

As I've googled, vaiofand does not support VPC-EA series.

Is there anything I can do with that or I need another laptop?

I'm using the following graphics card: 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] though the problem is not with the graphics card.

I've mentioned its temperature as the highest (64°C now btw). Seems like the notebook is always overheated and I cannot control the fan speed to make it cooler. And yes, I'm using the proprietary driver ATI/AMD FGLRX graphics driver.

I'm using Kubuntu 11.04.

Hi and welcome to AskUbuntu - what version of ubuntu are you using (edit your reply into your question). What is your graphics card (lspci | grep VGA) and are you using any additional graphics drivers in Additional Drivers - if so what is it? – fossfreedom♦ Aug 29 '11 at 21:01

@Xobb - Thanks - please try to edit replies back into your question. What version of Ubuntu are you using e.g. ubuntu 11.04, Kubuntu 10.04 etc? – fossfreedom♦ Aug 29 '11 at 21:18
Thanks, I'm new to this design so I was a bit confused. But already got it. Updated the post. Is there anything else I may provide about the system? – Xobb Aug 29 '11 at 21:21
I won't add this as an answer just yet - this guy here installed the very latest graphics drivers and it reduced the fan speed noise - maybe worth a try? ccgi.philfam.co.uk/wordpress/2011/07/11/66 – fossfreedom♦ Aug 29 '11 at 21:28

Try the very latest AMD graphics drivers:

In the download drivers section, select "Notebook Graphics/Radeon HD Series/MobilityRadeon HD 5xxxSeries//Linux X86"

Download the file and run it:

sh ati-driver-installer-11-6-x86.x86_64.run

aticonfig --initial -f

This should help the temperature of the graphics card and hopefully reduce the overall laptop fan noise.

Please note, this was absolutely valid for the 11.04, but when trying to make it work on 11.10 it fails. If you've tried that and afterwards you get your X server not running properly (black screen when the gdm/kdm should apper) go to rescue mode and launch sh /usr/share/ati/fglx_uninstall.sh to remove the driver. – Xobb Nov 4 '11 at 12:13
The driver has been updated since, now it works fine. – Xobb Dec 16 '11 at 14:00

Go to Control Center → Power Management → VAIO Power Management Viewer → Power Plan - Power Saver → Apply

The fan slows down, it takes about 30 seconds for the fan to slowly wind down but it it much quieter. It works.

Is this for Kubuntu? Your instructions sound like they are meant for pre-installed Windows... – WarriorIng64 Nov 27 '11 at 3:32
