I currently have a mid-2011 MacBook Air with a 27" Thunderbolt display. The Macbook air has the integrated Intel HD Graphics 3000. My main complaint is that my MacBook Air runs super hot, especially when I watch any video. Once it heats up the fan seems to stay on forever and is noisy and annoying. I'm not a gamer, this is my work machine; I usually am running Word, Excel, Adobe Reader, a web browser, and maybe iTunes all at once. I don't have any speed issues with my current setup, it just overheats constantly. So I'm thinking of switching to a Mac Mini, but I don't want to have the same overheating problems. How does the Intel HD Graphics 4000 perform heat wise? Is the fan always running on the newMac Mini when you crank it up? Would the storage drive choice make a difference? I would probably do either an aftermarket OWC SSD or the stock fusion drive.
