Hello, my problem is that since the last few days/weeks the fan on my Surface Pro 3 i7/256GB runs as soon as i plug it in. The CPU load is acording to my task-manager 0-1%. During battery use the fan almost never runs. I can have my Surface running on battery, no fan but as soon as I plug in the charger the fan goes off. Is there something wrong with AC usage? Also my Fan runs almost as soon as I open a MUI app, mostly at games from the Windows Store, Sometimes in the Music and video apps. However when running a "traditional" program the runs a lot less. be it VLC, XBMC or Windows Media Player.
