    What are you doing? Is the processor being held at 100% usage?

    I'm idling at 50ºC here, with my minimum fan speed set to 2000rpm using smcFanControl.

    I'm able to push it up to at least 83ºC by pegging both cores by running 'yes > /dev/null' in two Terminal windows, with the fan kicked up to 3000rpm.

    Use Activity Monitor to make sure that there aren't any processes gobbling up CPU time.

    If you just purchased it, Spotlight might be busy indexing, but that shouldn't that that long...

    That is quite hot, but it is expected because of its small form factor. You can always the thermal paste replaced correctly, and of course SMCfancontrol.

    Find a way to run both cores at 100% for a day or so if it is new to get everything distributed correctly.

    My processor cores would get up in the 80s, but that was during folding. Currently my CPU is 67C doing daily tasks.

    Hmm... that sounds alright, slightly high though. make sure your macmini is well ventilated, nothing's blocking the exhaust fan, got no clutters like books around and dont let it sit too close the wall. also, dont get it in the sun. my macbook tends to get hot when theres tonnes of apps running, especially photoshop. that should be normal. and you should take the temp readings when it's on idle.


    something off topic:
    you gotta be kidding me lol.

    ºCelcius is probably the easiest way to measure temperature... because isn't fahrenheit's scale not constant?
    0ºC is melting point (mp) for water, 100ºC is boiling point (bp) for water.
    tap water is about 20ºC, bearable water temp for skin is about 60ºC. a hot day could be 32ºC, and a lovely day is about 20ºC. A cold day is perhaps 10ºC.

    The Fahrenheit scale is linear, just as the Celsius scale is.

    It really depends on what you're used to. For outdoor temperatures, 70-80ºF is a nice day, 90ºF is pretty warm, and 100ºF sucks. :)

    Conversely, I've only ever measured processor temperatures in Celsius, so I know that 30-50ºC is normal, 60-70ºC is normal under heavy load, and 70-80ºC is starting to get a bit concerning. (The processor automatically shuts itself off at, what, 85ºC? 90ºC?)

    new mini

    I have a Macbook and just got a Mac mini 2.0 GHz yesterday. the fans on the Mac book will spin up to 5500 at 70c, under heavy use. The Mini fan speed hits around 2500 at 82c under very heavy load. Should the mini fan go higher? Right now it is sitting at 1500, 50c just surfing. just worried that the fan is not spinning fast enough when under heavy use?

    Update on my temps.I now have 54 c temps cpu A and the heatsink is in the high 40s. pretty low.Thanks for all of the advice.I will end up buying the imac soon and probably be worried about its temps.Until then,Thank you.
