Surface Book 2 throttles excessively, often down to 0.4 GHz

I've recently purchased a 15" Surface Book 2.

When compiling large projects in Visual Studio 2017, I find that the processor often throttles excessively, often down to 0.4 GHz. As a result, compilation takes several times longer than it does on my 5 year old MacBook Pro. 

The Core Temp app shows that the CPU at this point is at 50-55 degrees Celcius or so.

The following question touched upon this problem, but the proposed solution did not work for me:

Any ideas on how to fix this?

Thanks.

    So it seems that 1903 has made it even worse. I am getting throttled down to .4ghz almost non-stop with lid closed using surface dock.

    Welp I updated to 1903 and the latest Surface Book 2 driver and firmware package that was just posted. Sad to say that the CPU is still throttling down to .4 GHz. That removes any and all hope that Microsoft would've fixed in the next Windows release / next Surface Book 2 firmware/driver update.

    Lately the MS tech representatives have shown some interest in trying to reproduce and solve this issue. So i would welcome any method with which i could easily reproduce the issue for them. Currently i can only reproduce it if i run some build routines which i cannot share and they cannot use them in their labs. So it would be best if this is done with some standard testing software suites or software which is accessible on the web.

    Any help would be very appreciated by all members of this thread! and many other unhappy SB2 users :)

    a plugged in surface book in a room with temperature higher than 25°c 

    even watching youtube can cause throttling

    Yup I was able to demonstrate it for them just closing the lid of my SB2. I kept telling them the fan used to come on when it needed to cool and its no longer coming on with the lid closed. They said my apps were making it overheat. I said Outlook and a Chrome web browser? They said yes. I said OK lets close those two and open some other apps. They couldnt understand that it was not the apps causing the throttling but likely the heat and no fan situation. And this was tier 3 support who I spent a couple hours with on the phone.
