Old response for an older computer
I know this post is a bit old but I read many of the comments because I too have a Mac Mini at home although my friend has basically oft it here for over a year because he doesn't use it for anything but .app development.
Anyway To The Topic,
I have begun bitcoin mining which if you don't know why that's relevant here's a clue: Bitcoin Mining is decryption and calculations of giant blocks of code, these codes once complete are sent in to the bit coin network. A bit coin is 520$ right now and bit coin mining is RIDICULOUS on your hardware. My CPU was going to 90C so I grabbed iStat Menus to max the fan at 5000rpms or so to cool it down to 66C. Bit Coin mining uses your CPU and GPU to "Decode" or "Decrypt" blocks and uses a fair amount of internet to transfer the code.
Even more back to point and concluding,
My point was shifted because of thought distraction but I will say one thing about over-heating. My 27" iMac late 2012 heats up for very little reason other than its such a thin and claustrophobic design for the hardware. I took the display off my little 2005/2006 iMac and use an external monitor just because I like to understand how different parts work more because I'm hands on. So I would have to say heating up comes from: Stupidly tight casing (So most apple products (Not going against apple love their products)), perhaps less responsive fans, Over use of the hardware (Downloading 24/7, Gaming high graphic-ed games, constant use and sure things like bit coin mining which forces CPU and GPU to work at 100%.) and finally claustrophobic parts. Good day my 2cents.
