The latest windows update has again caused the internal fans of the surface book 2 to kick into overdrive at the slightest gpu use. I really wish Microsoft would check their latest firmware before releasing it, now we wait until Microsoft corrects their coding to fix the fans overuse in another update as they did last time to fix this problem in surface book.
Best work around is you can system restore to a point before this latest update. unfortunately I don't have a restore point, so no game playing for this computer until another update.
I am sure there are a lot with the surface book right now that are experiencing this problem as we both have since last Microsoft update, this annoyance will get a fix, hopefully sooner than later, they've done it before.
