Kubuntu crashed due to overheating

Kubuntu crashes due to overheating. It crashes while playing America's Army and crashed again while playing Alien Arena 2006. I've not played Alien Arena under windows but America's Army plays great without a single overheating incident.

If this IS due to overheating, even if it doesn't happen under windows, it's a hardware problem and has nothing to do with kubuntu.
If it's a software issue, you need to provide more information.
What video card and drivers do you have? What are you using to play these games (wine?)
What makes you think it's an overheating problem? How long into the game does it crash? Does your computer restart or freeze or does X crash or does only the game crash? If it's only the game, can you get any logs or console output?

I'm running a Acer Aspire 1524, which comes with a AMD Athlon64 3400+ and a NVidia GeForce FX Go 5700. The video card drivers are the ones available in Kubuntu's default repositories. I was running America's Army Linux version.

The game crashes about 5 to 10minutes into it but it also crashes in non-graphics intensive scenes, like the medic training. The OS is restarted with a error message claiming it was due to overheating.

It is the whole OS that crashes. When it crashes, first the computer shuts down X, a text prompt appears for a moment (non-interactive) and then the kernel error message pops up, warning about the high temperatures.

The strange thing is that even yesterday my computer shut down due to overheating while I was using Firefox (I had a lot of tabs and windows opened) and I had kdeveloped open (I was compiling a C++ pet project of mine). Therefore I believe that the problem isn't originated in AA but in the OS itself. On the other hand, I do a lot of computer-intensive work under windows (a lot of gaming, a lot of CAD work, some number crunching, some development, burning and watching DVDs) and I never had any problems involving overheating, which seems to rule out a possible hardware problem.

Well that is exactly my bug ( 22336 ). So you may mark this entry as duplicate.

There seems to be something acer specific somewhere.

Just a few remarks:

* Problem occurs when CPU is used intesively for a few minutes (amd64 version)
* Problem does NOT affect Suse 10.0* amd64, debian x86, Windows XP, Windows XP x64

 -* - Suse setup fails with overheating unless I preload powersave-k8, and cpufreq-* modules manually. Unfortunately that does not help with k/ubuntu.

Definitely software issue (most likely handling of Acer bios calls)

Forgive me for replying to this without having any news about this issue. Yet, I would like to know if this particular problem is going to get fixed in Ubuntu 06-06. A couple of minutes ago my computer just crashed again due to overheating (compiling) and right now, after restarting, it seems that the computer's fan just got stuck on medium intensity although I am only running a single firefox window for about 20 minutes.
