[SOLVED] Can VRM even throttle itself if it has no thermal sensors installed?

My Acer predator laptop has a gpu that doesn’t have any thermal sensors installed in its vrm, (for all I know atleast). There’s no vrm sensors showing up in any 3rd party monitoring software. Is it possible for the vrm to thermal throttle if it doesn’t even have any thermal sensors?
The heatsink that covers the vrm section also gets a lot more heated than the rest of the sink , I.e the cpu/ gpu core and Vram.
 
Solution
Any power delivery circuitry worth its salt has its own set of protection mechanisms, even if the computer can't see it. There may be something in there already limiting how much power it outputs based on temperature.

There’s every chance it doesn’t have a sensor.

The VRM can thermal throttle based on one of the other sensors. Not ideal, but then it’s Acer, they don’t do things in the ideal way, they do things in the cheapest way.

the thermal performance on the predator is lousy, and the VRMs not having a temp sensor of their own can’t be helping matters.
