The temps I've been getting with my mini have been entirely unacceptable, and before anyone comes in saying that "the chips supplied to apple have a higher thermal envelope than the consumer chips so dont worry about it" let me explain my concerns. While the proc may be designed to operate in this environment, the other components such as the capacitors, north/south bridge, WLAN/bluethooth chips, the solder and even the PCB substrate more than likely arent. I run an IT startup out of Portland OR and currently we are the only shop in town (that we are aware of) that offers hot air and IR rework of circuit boards, and as such I've seen hundreds of machines come through with thermal damage. Most notably the machines running the nvidia chips from a few years back. So I began my quest for a cool mini. I installed smcfancontrol however I didnt like not having heat thresholds, so I ditched SMC and went to good old fancontrol. I set my minimum fan speed to 2500rpms (I figure the fan has a max RPM of 6,XXX, so setting it 200rpms above the mini servers default wouldnt cause any real undo stress, plus the cost of the fan is far less than a new logic board) and had it spin the fans up higher after 73*c. This lowered my temps a bit, but they were still outside of my comfort zone. I flipped my mini over to inspect the air intake and noticed there were only a few millimeters between the glass desk my mini was sitting on and the intake vents. I went out into the garage, cut off an inch long piece of 3" round PVC and made a little pedestal for the machine. Fired it up and immediately noticed the temps were cooler, I have dropped my temps approx 6*c. My idle temp is now rock solid at 58*c and my full load fluctuates between 72-75*c. I may still end up disassembling the machine and lapping the heatsink to give it a nice mirror finish, I just dont know if I'll get the time to do so soon. So everyone out there with a new mini, record your average temps then put some sort of stand underneath (be careful not to block the air intake) and see how your temps fare.
