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.

    This is the post that has helped me out.

    Next easy solution is to disable the Intel dynamic platform and thermal framework which overrides almost all software-level control of the TDP.

    "Go to control panel, devices, find "Intel dynamic platform and thermal framework processor participant", de-function it. If not able to do so, you can just go to c:\windows\system32\drivers\dptf_cpu.sys, rename it and restart, and the TDP throttling feature seems totally gone from my system (don't forget the disable it in the control panel for a double security). The temperature of my CPU has soared to 100 degree celsius under both CPU/GPU stress tests and the system just went down locked without a single throttling."

    Happy lovers day!

    Wouldn't disabling thermal framework etc potentially lead to an overheat that could cause damage to the hardware? Also wouldnt it possibly cause the battery to last even less than it does when not on AC power?

    Yes if it was actually overheating, IMO these devices are giving false positives and throttling down on minimal use a 3k dollar laptop should not overheat when your looking at your email.  Doing Zhan's suggestion has at the very least allowed me to work until Microsoft address this issue which i'm not holding my breath for.

    my concern is the fan isnt even coming on when the lid is closed. i think it will overheat/damage the hardware if it has zero cooling.
