Yes, it does, 150%, fully explain the behavior. Laptops are not meant to be overclocked. Neither the hardware nor the enclosure are designed to have ANY amount of tolerance for a dynamic change in thermal metrics. They are precisely designed to operate within the exact parameters that each and every component left the factory calibrated for. Anything you do that upsets that balance, whether it's overclocking the GPU or graphics card, making voltage changes, running it in extremely warm high ambient room temperatures, operating the machine on your lap or on the bed where your pants or blankets might block airflow through the very minimal cooling vents, even for short periods of time, can all upset the cooling calibration.
Anything it wasn't meant to do, and even some things it was meant to do, when done under conditions it was not meant to be operated in, can not only have a dramatic effect on the internal temperatures of EVERYTHING inside the case, unlike a desktop where one component is a lot less likely to have an immediate effect on another components thermal condition, but can easily and quickly cause permanent damage to components when the conditions overcome the cooling designs ability to remain within spec.
Even bone stock laptops that are used for extended gaming, and no matter what kind of laptop it is, called "gaming" or not, gaming on them is a poor idea, tend to eventually exhibit thermal problems. There is simply not enough room inside these enclosures to provide adequate cooling even for the hardware that it comes with and is configured for, in many cases, under sustained extended conditions, much less when you throw that entire delicate balance off by doing something like overclocking hardware that was already at the edge of the limit in terms of what the cooling system could reliable keep in check.
And if there is an actual problem, such as a faulty fan OR a fan or motherboard that have burnt out some portion of the system such as wiring or a diode used for thermal monitoring, the problem could be more immediate or even instantaneous. If this unit is under warranty I would absolutely RMA it now, not later.
For the record, there's nothing here I disagree with from the scientific viewpoint. But I disagree under my cirumstances - one of the things I've done recently was to choose the global option to default to the integrated graphics unit, the GPU [fan] is still wild, so no amount of overclocking (or the reverse) has caused this issue. I am out of warranty, so that's a no go. I opened it up and inspected it and I don't see anything weird (as much as one could tell without going deeper anyway). No discoloration of wires, connections are properly seated, etc.
Now, here's something weird, and I wonder if anybody else has seen something similar, and I'm still in the process of testing this.
I have had my laptop running for several hours without this issue at this point.
I stopped using Microsoft Edge. That's it.
I have a game running in the background now (its not crazy), with the intent of making sure the GPU is actually under a load. Even at 80 degrees Celsius, the fan is running at 3000 RPM with a stable temperature. I did a google search, it seems like people have been having GPU load issues with Microsoft programs, oddly enough, that is actually a thing.
Now, I'm not saying this makes any sense, especially since my GPU loads were still low despite using Edge, it's purely an issue with why it's decision to spin up the fans unnecessarily. Will update in a couple of days to see what happens.
UPDATE: I just realized I had "SILENT" still selected, so it was only doing what was necessary to keep it under 80 degrees Celsius.
I switched to "BALANCED" and now it's spun up to a reasonable 4200 RPMs and keeping the GPU down under 70 degress Celsius.
I switched to "OVERBOOST" and the fan spun up to, what appears to be a max of, 5,100 RPMs, temperatures staying a little bit cooler. But the sound really isn't bad.
Which brings up a whole other issue -
IF Microsoft Edge is the issue here, it's very strange that not only is it causing an unnecessary spin up of the fans, but several thousand RPMs greater than design as well, as if it were some kind of emergency that my CPU and GPU are about 38 degrees Celsius.
This just keeps getting weirder and weirder... Why can't I ever have normal computer issues?
