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.

    finally some good news, sort of.

    I got a reply from MS tech that they have identified the cause of the issue and also reproduced it in their offices. They say the issue was already seen in some other laptops and also some PCs. Of course it will now take time for some vendor to wake up and fix their drivers. I'll post more info after a followup call some time this week.

    So it seems the attention was raised and things are moving, thanks to all of you posting on forums and twitter!

    I can also confirm that placing a small USB fan behind surface technically fixes the issue. I was finally able to use SB2 without constant slowdowns for a whole day! Thank you very much for the suggestion.

    I heard about someone doing such a thing, not released yet though, I don't have the link to it, but I recall it being on Reddit a few days ago

    I just uninstalled Avast and the problem is still here :) i guess the only thing we can do is wait or make a program to change the power slider every 10 seconds
