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

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.
