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.

    I've already sovled the throtting problem. In my case that is not a software bug but a hardware trouble, my surface book's cpu fan is broken, completely not running. So I sent it to microsoft and they fixed it up.

    Never down to 0.4Ghz again

    It's a cold December but I still got this problem recently. The problem seemed gone BEFORE I installed "2018-12 Cumulative Update for Win 10 1809 x64 KB4483235". However, it came back AFTER I installed this update!

    Do something Microsoft!

    Will never buy a Surface as primary PC again.

    Exactly the same proble, cores running at around 0.5ghz. Laptop completely unusable. CPU temp is very low mid 50s on all cores.

    Only happened after the recent batch of updates. Spent $3K+ on this laptop fo the fully spec'd one. Its almost unusable

    Mines hasn't throttled to 0.4 ghz since the colder temperatures in December. All firmware and windows updates are installed.

    yeah this issue is affecting me as well, latest Windows 10 updates on my SB2 15". Happens when I'm gaming, my frames that usually sit at 60fps, suddenly drop to 30fps until I use ThrottleStop 8.70 to further lower my CPU power draw and then frames go right back up to 60fps.
