MacBook – Thunderbolt to VGA connector makes the MacBook Pro Retina very hot

bootcampmacbook prothunderboltwindows

I have a new Macbook pro retina display, i7, 16 GB RAM and NVIDIA GeForce GT 750M.

I have noticed that when running Boot Camp with Win 7 and I plug in my HP VGA monitor using a VGA/thunderbolt adaptor, the top area above the function keys get extremely hot.

I have made sure I have the most up to date drivers for my graphics card but still the issue persists.

Has anyone else experienced this?

Well your macbook is simply utilizing the nvidia video card and that produces more heat. Since you are running Windows it may not be using resources as efficiently as your MacOS.

Your macbook typically runs off the onboard video card and switches to the hotter running nvidia for intensive apps/games.
