Well, there's no bug, which is why this thread persists. Flash Player doesn't have magic properties that allow it to add additional dust to the inside of your computer, nor does it have the ability to choose a poor thermal management design. Some Flash content uses a lot of CPU, but the reality is that your machine should be able to run at 100% CPU without overheating. If the machine is overheating, it has a cooling problem. We can't fix your cooling problem from software.
Given that this thread is super old, I'm going to lock it. In general, if you have a decent GPU with current drivers, Flash Player will offload as much video and graphics processing as possible to the purpose-built, energy-efficient GPU on your system, as long as you have hardware acceleration enabled (it's on by default).
If your machine is constantly overheating, go buy one of those cans of compressed air from your local office supply store, take the machine outside, and give it a really thorough dusting. Check to make sure all the fans are spinning as expected, and that you're resting the machine on a surface where air can actually enter and leave all the appropriate vents. There's no magic here. If a good cleaning doesn't solve the heat problem, it's time to consult your manufacturer about an in-warranty repair, or your local technician for an evaluation. They might be able to examine the machine and improve the cooling situation with better fans, etc.
