I need to run an MPI process that will demand 100% of all 4 cores of my mini 2012. Would it be safe to run it for about 60-80 hours??? I've tried it for about 10 min. and temps go up to between 95-100 degrees celsius. If it is not safe safe is there a way it can be done without damaging the mini? Fan runs at about 4500rpm @95 degrees
Got a tip for us?

As said, if the temperature were too much for the Mac Mini it would switch itself off.
More importantly, modern processors are aware of their own temperature, and will throttle their performance in order to remain within a target temperature. If you've seen a processor mention TDP then this is partly what this refers to, along with the maximum power that the part should draw.
While this means it's safe to run the processor for long periods, it also means that your Mac Mini may only run at the true maximum speed of its processor in short bursts; during prolonged use it will settle at a level that keeps it within its target temperature. This is one of the things that distinguishes a quad-core Mac Mini from a quad-core Mac Pro (once you've adjusted for other differences) as the Mac Pro is designed to run with the processor at full speed for prolonged periods (though it presumably still throttles a bit if you also push both GPUs as well).

I have the same concern as I'm thinking of using my new 2012 i7 mac mini for 720p livestreaming. On my 2012 i7 macbook pro, it draws 90% cpu, 5000rpm, and 180-195 degrees fahrenheit. I use laptop fan cooler, and it helps bring it down 10 degrees. I haven't dared 1080p for more than 1 hour stretch in fear of thermal shutdown.
Are there any external cooling either passive heatsinks or fans that are effective for the mac mini?

The processor may be able to take the heat in the short run, but heat does shorten the life of components in the long run. With an architecture where everything is soldered onto the logic board, repairs are no longer feasible. So, while your machine running hot does not kill it now, it will shorten its life (it is a bit like smoking for humanoids)
Your MBP supports hardware accelerated H.264 encoding via Quick Sync (for example for Air Play). This reduces the CPU temperature and allows 1080p H.264 encoding in realtime.
Yes. Turbo Boost reduces the CPU speed automatically, if necessary. You can see the details with this tool:

Wirecast uses the Mainconcept H.264 and x264 software libraries, which means that Wirecast does not use Quick Sync.
