Hi Edwin ,
Thank you very much for replying to my post.
So there is no danger at all to my new MacBook Pro / Retina , that is very great news.
You mentioned , if I "am that concerned , to run at a lower setting " , can you please explain how to do this ? Also for someone like myself , what would be considered an out of control fan speed or a damaging fan speed and temp. ?
I don`t mean to high-jack this thread , but , I am also wanting to download Sid Meir`s Railroad and Pirates. My understanding is that where they are more of a simulation type game ( app ) , would I be correct that I could run those at normal ( default ) settings ( if there are any choices ) ? In other words would the 2 games ( apps ) mentioned cause the fans to spin up , as they do in GRID , I say no , but I must ask an expert

.
Thank you again for your help in understanding that I CAN play "GRID" without destroying my 3 month old MBP-R , that makes me feel a lot better.
Take care , and Happy Easter to you and yours.
Gary
PS:
What about Lego`s LoTR`s , would that be considered a stress game ( app ) or more like I hope Railroad and Pirates to be.
TY , Later
