That is because of two features that are built in to the
processor/motherboard. The processor has CPU Overheat protection and a
thermal shutdown. These two things make it so that the CPU lowers its
clock speed until the heat is removed or if that doesn't work, it will
shut down to prevent damage. It's a really nice feature that they've
incorporated into the P4 series. Just FYI, the maximum temperature that
these processors can reach (according to the development papers) is
around 80C. That is extremely hot and it won't even reach that temp
normally since the CPU will just slow down to a stop if there is too
much heat :)
