Another Workaround

i also come across suggestion to control cpu usage through power options by controlling Maximum Processor State. Set it to 90% or below.

Power options - Advanced settings - Processor Power Management
Power Options - Maximum Processor State

This trick should do it if you not even want to change bios settings. I personally did not try this, as i think the bios will do a better job.
