overheating in ubuntu 12.04

[pscool]

i am having ubuntu 12.04 and windows installed. In ubuntu if i am even using firefox and one or two light applications, the fan speed increases rapidly and temp rises to 70. Even if i close all applications, it takes a lot of time for fan speed to come down. This does not happens in windows. I read somewhere its a graphics card issue but i am having intel hd 3000 (integrated).can anyone help

What computer/laptop are you using ? Tell us your system specs ?

i am using hp 430 laptop, 2nd gen i3, 2 gb ram, intel hd 3000 graphics.

Certain users have reported that updating the bios to the newest one fixes certain heat problems when running linux, also here is a tool called Jupiter that can be installed which will better manage devices and power on your laptop to keep things cool:

Also, installing the latest 3.6 kernel will help with power management and driver issues that may cause overheating as well:

i installed jupiter, but the temp reduced from 70+ to 65-70. Then i have upgraded to 12.10 now and currently i am using only firefox but the fan is still making noise and temp is 60-65.Would BIOS update help?

A temp of 60-65 is not bad, for a laptop -- unless you get MUCH lower temps in Windows.

There was a kernel bug in recent Ubuntu versions that prevented the processor from throttling back to idle state, causing it to run faster -- and hotter.

That bug did not get fixed in Ubuntu 12.04 and don't know if it got fixed in 12.10.

Jupiter is really about the only recourse you have.

The op just have to update the kernel

it is a feature bug with intel graphic power management
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/

here the link for quantal kernel

Download the proper kernel for your system
down load one of each linux-headers linux-image
x86 for 32 bit
amd64 for 64 bit

if that does not work then
run this command

sudo bash -c 'echo "options i915 lvds_downclock=1" >> /etc/modprobe.d/i915.conf ' && sudo chmod 755  /etc/modprobe.d/i915.conf

reboot

i agree 60-65 is not bad, but if i use a few more tabs and one or two more application the temp is going to 78-79 . i also ran this cmd and rebooted but not much help
sudo bash -c 'echo "options i915 lvds_downclock=1" >> /etc/modprobe.d/i915.conf ' && sudo chmod 755 /etc/modprobe.d/i915.conf
i want to ask will installing a fresh copy help, as continuously running at high temp might degrade my hardware of the system
adn secondly at which mode should i keep jupiter at, i.e maximum performance , on demand or power saver?

[idoitprone]

it didnt help much?

strange

post the result of

modinfo i915
uname -r

cpu are rated to run under a certain temperature
if they suprass it thne it is a issue but 60 c idle is a little too high
it should be 45-50c idle
