That sounds like some process for whatever reason stresses the CPU and
your hardware is broken to the point where it cannot really run at
Now people will start telling me "this is how laptops are" but I still
call BS ... if you can't run it at full speed and still under warranty
contact the vendor and demand a fix/replacement. Otherwise try to
remove dust and or check your heatsink / cooling.
