Thanks - I meant over-riding protective thermal controls.  Put another
way, does giving users the ability to control laptop internal
temperature introduce a level of risk to hardware like CPU and HDD
through over-heating?  I guess these fans are there for a reason.

Sorry if this is a dumb question - I was curious though.
