Haven't had time to figure it out yet, but supposedly can tweak top level throttle parameters. May work, who knows...
 
If accurate, BIG IF...  shows the motherboard temperatures out of the box. Should then allow the reg file posted earlier to control throttle percentage and keep the central unit cool while chasing a balance of speed vs fire hazard.
 
Thanks Jim for your input. Resonates with what the designers are saying that the core is engineered to fly at 100% without fear of frying something. Laptops and thin Macs maybe needing a bit more caution if you are closer to the Equator of in Death Valley.
 
Got a Dell i7 desktop opened full bore by default. My laptop was cut back to 35% by default causing all kinds of problems with the Presonus card. Upped the thing to 50%. ThrottleStop reports max 45C, way too uncomfortable without opening a window for humanoids, but under the fry point for the hardware. As advised, throttle limitations may be set in the BIOS in which case surface software attempts to disable will be overriden.
