    Hiya all,

    Just upgraded my beloved PB g4 to a new i5 mac mini. Just giving it a workout with some handbrake encoding and the processor is getting hot!

    It's up to 80 degrees c plus and the fan is only spinning at 2000rpm. Should the fan be going quicker and what sort of temps are the processors capable off?

    Readings are from istat pro widget and not done a restart yet.

    Any tips would be great.

    Cheers c

    cpu generally takes around 100-110c and then the system will do a autoshutdown, gpu's can be even hotter. since you are putting it under heavy stress around 80 is probably what it will be at most (unless the vent is covered). Seems apple has gone to the limit of what is possible to get in that small space and only that small fan

    I use smcfancontrol to bump up the fan rpm before I start handbrake. I have a 2009 13" MBP and I find that it's waits way to long when running handbrake to ramp up the fans. IT will be 90 - 100C and the fans will still be spinning at 2000 rpm.

    All I can say is make sure you buy the apple care I have just had a 18 month old MacBook pro sent back after overheating new logic board later and all is well. I really can not see these mac minis lasting long with the temps I have been seeing. In my experience the worst thing you can do with any computer is run it hot as it will cut the life of the computer in half.

    I doubt it will have that much of an impact on longevity in a mini. They don't go through the same rigors a portable experiences... however, Apple Care never hurts.

    My new i5 mini also seems to run a little hotter... or at least hotter than my 2010 macbook pro, which seems to stay comfortably at about 60c when I'm doing normal activities (e.g. not video/gaming). The mini seems to hover around 70c. Not sure if this is due to the fan speed... as the OP pointed out the fans don't seem to run that hard.
