Hi Gang,

Using a 2013 MacMini for theatrical playback. Quad-core i7 w/HD4000, 4GB (3 1/2 effective), OS 10.8.5.

Driving a 1440 x 900 control monitor via DVI and 1080 projector via HDMI.

From a cold boot everything is fine. Eventually the HDMI starts flaking out and disappears completely. Replaced the Mini with my 2012 MacBook Pro (Dual-core i7 w/ HD4000 & 8 GB RAM. The setup works flawlessly with MacBook & PC.

Suspected heat as the problem, I downloaded Geeks3D GpuTest & Temperature Monitor. On a flat surface, 68 deg F room, Geeks3D GpuTest (OS X x64) - FurMArk OpenGL Engine, windowed at 1024 x 640; the CPU/GPU overheats and throttles. Temp rises to 103-104 deg C then jumps back to 90 in an endless cycle.

Is the Mini cooling system really that inadequate? I've already made four trips to the Apple store until I finally convinced the geniuses to replace a bad hard drive. Not impressed with the "Genius Bar" staff.

Any thoughts are greatly appreciated.

Thanks!

The Mini cooling system is not that inadequate. Either it's full of dust or the cooling fan isn't working. At those temperatures it should be sounding like a 747 taking off. If not, the fan is the problem.

Thanks!

The fan is audible, like a loud laptop fan...

Then I would suspect either that dust is blocking the cooling system or that a heatsink has come loose.
