I hear that many laptops that run on Linux overheat very quickly. :( (mostly on Ubuntu Fiesty!)

Is this true?
Is there anything I can do about it!?
Some laptops' fan settings were messed up by the new kernel used by Feisty, and obviously that can cause heating concerns. There are a number of ways to fix this:

1) revert to an older kernel version.
2) set your fan to run at a constant speed, or at the suggestion of hardware thermometers, rather than software (not available on all laptops)
3) dive into kernel patch land and find something that fixes the fan problem

Linux shouldn't have any significantly different heat output from any other operating system, so as long as your fan is working your laptop should be just fine.
I found that I had to set my CPU scale very high constantly to keep the fans running. Problem with my laptop is that it decides fan speed based on current clock speed, meaning that if I let my laptop sit at it's slowest speed(Which it naturally wants to do if I'm not doing anything hard to the CPU) the fans don't turn at all. My fix was to find a program to set my clock speed. I set it was Mid-High and it keeps the fans running 24-7(Although they do speed up during high CPU usage times).

I was actually able to find a docklette to do the job. It tells me my current CPU clock speed and lets me change it how I please. In Kubuntu, I was right there with the power management options, but not on Ubuntu.
