Hi I have a mid-2014 MacBook Pro with Retina Display (the one with the nVidia 750M) The laptop doesn't get hot whilst normal operations, mainly internet browsing. Today I was playing a game, Plague Inc. Evolved, and after an hour or more, it started to get hot, and I didn't hear the fans spinning. I know that the fans are designed for the least noise emission, meaning remaining silent. But I a few weeks ago I was using Maps on it and heard the fans working. Can anyone suggest software which supports hardware monitoring? I found this app http://www.macupdate.com/app/mac/23137/fan-control but found out that it doesn't work on MAC OS X Yosemite (the OS X Version which I am using). Can I have suggestions for apps which provide good hardware monitoring? I also found this App: http://bjango.com/mac/istatmenus/ , is it any good? other suggestions are welcome I am new to Apple Computers and would really appreciate the help, as I always received on these forums.
