What kernel version are you running? Newer (3.10+) kernels use the intel_pstate driver by default, and the older power management tools won’t work with it, and unless configured with the new “Thermal power management deamon” your fans will likley run full on.
2 weeks ago I downloaded OpenSuse version 12.3 and installed it so I know its a newer kernel. Im new to linux. Do you think installing a 32-bit OS would have effect on how hot the CPU gets? Right now I have the 64-bit. Those commands are unfamilar to me, Im looking for a quick solution as I start school in a few days and need to use my laptop for school work and not have it fry… M
Okay, if you installed just the stock Suse kernel you don’t need to worry about the newer Intel power management driver I was talking about.
And 32 vs 64 bit makes no difference. You can reinstall if you like, but I would not expect different results.
I would suggest perhaps laptop-mode-tools, which you can do from the Software category in Yast. Installing that will likely not magically fix it, but it may be worth it nonetheless.
To clarify: Do the fans run full on ALL the time?
Also, we should verify if it is a power management / sensors issue, of if perhaps there is just some runaway resource hog program that is causing high load and thus high temps and so the fans do as they should and run. To determine this, when the fans are running high, use the terminal program Konsole and type the command ‘top’ and see what programs are listed first. (Alternatively, hit ctrl-f2 and click on the system console monitor icon to the left of the text box that is displayed at the top or your screen.) Is there something running with high CPU utilization, like updatedb or nepomuk, etc?
Thank you for the swift replys! My CPU load always sits very very low, the laptop will even get this hot while sitting in the bios menu and even when it had windows installed before. Im running iceWM, and I see nothing taking serious use of the CPU. It just gets hot really quickly . The fans I can hear running, but only minimal speed and they only speed up when the CPU load is high, not when the cpu is hot, (which is ALL THE TIME). Ive been doing some research and it seems maybe cleaning out the fan area with a dust cleaner might help? but the laptop is brand new, I guess im not sure whats causing the CPU to get so hot. I’ll be trying out the laptop-mode-tools in the meantime
Getting hot in BIOS is not uncommon. However, if the fans were running high when Windows was installed before, then this indicates its not a Linux issue, but more likely hardware related.
If there is nothing using the CPU and its getting hot and the fans running high, and it did this in Windows as well it again indicates hardware.
Cleaning out the fan and vent slots with some compressed air might help, but if the laptop is brand new I would consider having someone look at it (if it’s still under warrenty you can likely send it in for service) or possible even returning it. Have you researched this to see if it is common issue with this model?
I once had a Compaq notebook that was notorious for having the CPU heatsink come loose, causing the CPU temp to sky rocket.

since it is new, and since i very much agree with LewsTherinTelemon’s
opinion that it is a hardware issue (because the problem exists in
all of BIOS/Windows/Linux) i strongly advise you to remove all traces
of Linux and return the laptop to the place of purchase for repair or
replacement…
advice to remove Linux is because some manufacturers use
installing any new OS as an excuse to not live up to the warranty)

I have same problem only in openSUSE. Have this problem in version 12.3 and 13.1, older versions not tested.
CPU fan just turns off while PC working and back not turn on even after reboot.
I should remove battery, power cable and wait 1-2 minutes for start work CPU-fan again, after turn on computer.
I tested my laptop with Windows XP/7/8, (K/L/X)Ubuntu, ArchLinux, Debian, Fedora.
In this systems my laptop works fine.
make sure the air vents to the fan are not clogged, could be a hardware problem, they might just need some dusting. do u use your laptop from your bed, it can do that since the blankets can clog the air vents
All clean and sensors works fine, because in OpenSUSE 12.3 I use this script for emergency power off [Bash] Tempmon.sh - Pastebin.com](Tempmon.sh - Pastebin.com) But after two weeks, my patience was over, I installed Kubuntu. I do not see the laws of this problem. It works fine, cools to a temperature of the fan stop and maybe sometimes just does not start fan back. I was hoping that in the new version of OpenSUSE 13.1, this problem will be solved, but it is not so:(
I installed laptop-mode-tools and after 12 days of using OpenSUSE, I think my problem is solved. CPU-fan works normally, fan stops if cpu cold, and starts if cpu hot. Previously, this problem occurred every day or at best once in two days.
