To the experienced, I think reach dangerous temperatures in Laptop with Ubuntu. The version is 12.10 and the extras just installed lm-sensors and java.

root @ ubuntu :/ home / ricardo # sensors acpitz-virtual-0
 Adapter: Virtual device
 TEMP1: +79.0 ° C (crit = +99.0 ° C)
 temp2: +29.8 ° C (crit = +99.0 ° C)

 coretemp-isa-0000
 Adapter: ISA adapter
 Physical id 0: +90.0 ° C (high = +86.0 ° C, crit = +100.0 ° C)
 Core 0: +90.0 ° C (high = +86.0 ° C, crit = +100.0 ° C)
 Core 1: +88.0 ° C (high = +86.0 ° C, crit = +100.0 ° C)

This Windows walks in their 50 º C, but linux is a heater that melts the battery quickly. The Laptop is a Samsung 300v3a s03pt, i5 second generation, intel hd 3000 and nvidia does not interest me install gt 520m. I tried that already has linux driver optimized. What can I do? The bios it is updated, the fan runs at background, and yes it is only on linux.

I am pretty sure you are having issues with that Nvidia device you don't care about. Take a look at this:

Community Wiki: OUCH! Laptop running SUPER HOT after 12.10 upgrade!

Basically the graphics card is a primary source of system heat along with the system processor. Assume any GPU processors or embedded GPU processors are a source of heat in most cases and realize most systems have more than one GPU which combined produce more heat through the system than the processor.

Also refer to the linked article for attempts at cooling the main processor as well.

Not updated, but it was installed again. I installed the nvidia drivers as follows:

sudo add-apt-repository ppa: bumblebee / stable

sudo apt-get update

sudo apt-get install nvidia-bumblebee bumblebee

Then to test the terminal writes:

glxgears <- for Intel board

optirun glxgears <- for nvidia card

The temperature of the CPU is much higher than gpu

In the wiki I linked the commenter mentions he wasn't getting much of a change from using open drivers for their AMD processor. Not sure what processor your using but you may want to follow his lead. –  Brandon Clark Mar 10 '13 at 17:36
    
I don't know how this is coming for you but I saw a post of someone having over heating issues with 12.10 who switched to the 13.04 and no longer have the issue. If I remember or find where I saw it I will link it. –  Brandon Clark Mar 14 '13 at 11:20
