Installed the 188.8.131.5280 yesterday, maps is working now, showing all the roads and routes. Fan is quiet, it's been running for 24h now.
Bad news for me is that Adobe Premiere CC 2015 isn't working again. It did finally with the manually installed 184.108.40.20600. So I'm rolling back.
So far so good.
Yesterday I installed the intel beta drivers 220.127.116.1180 and updated windows 10 to latest version 10586.104.
No fan noise, at all everything seems to work properly.
I use Autocad 2016, and it work even better.
Strange behaviour, I'm the opposite of quadxeon, bonzer2u, jnjroach... but i found no problems so far...
Hope will be the same to you, soon
