Surface Book 3 Overheating During Updates and Routine Downloads?

I just got my Surface Book 3 yesterday, and I had the same issue with overheating described here when charging. I don't know if that's bc it was charging or not, but given my awful experience with overheating with the Surface Pro 3, I'm tempted to return my Book 3 because of these overheating issues.

I unplugged it for a while after having PROCHOT stuck on and it seems to have cleared for the time being.  It will occasionally hit PROCHOT, which is entirely normal, but it isn't stuck on it anymore when doing nothing. 

For now, the Microsoft tech and I are going to load the recovery image and then go from there to see if the issue persists.

Thanks for the quick response! Where did you find statistics/analytics about the PROCHOT status?

We used HWiNFO to start creating logs. It's a surprisingly powerful little program and it's free. 

To be clear, we were only concerned about the thermals because I had gotten the little thermometer to pop up several times despite it not really being all that hot. 

If your experience is anything like mine, then a Microsoft rep should be getting in contact with you shortly.

First off, the specs are: 13.5"/i7/32GB/512GB/1650 G-Max

Not sure if this will be the case for all users, but I am currently troubleshooting a issue with the Surface Book 3 going into a thermal throttle state from just restarting or trying to update even basic things. 

The first few days were fine - though attempting to run Minecraft didn't actually engage the dGPU for some reason.  Eventually got the dGPU to work by installing NVIDIA's GeForce Experience, or whatever it's called.

Then I noticed that the fan would spin up even when the SB3 should have been in sleep mode; I fixed this by just having it hibernate instead. Since then, I haven't heard any fan noise at all, even when the thermals were hitting well into the upper 90s C and even a few cores hitting 100 C.

Now, I can't seem to cool the thing off. I was trying to install Adobe Acrobat Pro and the latest Intel drivers (apparently one was released on 5/20?) the screen shut off and a little thermometer popped up (which I assumed, and later confirmed, meant that it had overheated and shut down to prevent damage).

Like I mentioned just above, now I can't seem to get the darn thing to run cool enough to even install it's routine updates. I have a box fan pointed on it to try and help, but even that doesn't seem to be effective. 

When last I checked (which admittedly was a few hours ago now since I'm trying a factory reset to see if one of the updates caused this) the CPU was capped out at 400 MHz, but it hasn't overheated since. It sure does take a heck of a long time to do a reset when your CPU is capped to 400 MHz. 

I'm hoping that this factory reset will fix the issue (hey, ya never know 'til ya try, amirite?), but otherwise I assume that I will likely have to warranty this particular SB3. 

Not really sure where I was going with all of this, I guess I was wondering if this is something that could be caused by updates and drivers or if there is a more serious hardware issue. 

I spent far too long trying to see if I could force the fans to spin regardless before just giving up on that. 

I'll add a link here that has a picture (would've done a screen cap, but it's in the middle of resetting) and some video showing what I'm talking about.

Thoughts or suggestions?

Another thread was talking about if 13 inch SB3 has a fan or fanless. Are you talking about the fan in tablet or base?
