The video of course is fully buffered.
So a CPU can slow down because of heat?
I thought the PC would shutdown because of overheat.
How can I know when my PC slows down because of heat?
The CPU is able to get to 100% though.
If the cpu gets to hot too quicklyit will shut down. Now if it's gradual incline and if the cpu can protect it self, There an overheat protection mode where the cpu will reduce performance until it cooled down enough to run in safe temps.
Here an old video showing off the ability. (Today amd cpu have the same ability as intel cpu in terms of overheat protection compared to back then)

Now how to know when the cpu slows down due to heat, well if this was a lga 775 Pentium 4 or later cpu i would say uses cpu-z and watch the GHz and see if they drop after using a stress program like prime 95.
Although from the info you gave us, the only 2.4 ghz p4 i can find is on 478 socket, so (just like my p4) that method wont work.
So all i can say is, use a temp program like speed fan or HWmonitor and tell us the temps are. (only 2 temp programs i know that work on 478 socket cpu. )
