Hi Everyone,

 

I've been reading information about the temperatures people are seeing from the Mac Mini i5 2.5 and i7.

 

I've recently purchased an i5 2.3 Mac Mini this month. I'm concerned that this is too hot. I'm not really using anything intensive. Mainly browsing, icloud services, Facetime, MSN, Skype.

 

Using iStat 3.18, I get the folloiwng figures:

 

Airport Card     53 degrees C

Ambient          60

Ambient 2       56

CPU 1            94

CPU A            88

CPU Promixmity   79

Mem Bank A1      62

Mem Module A1   60

Mem Module B4   50

Power Supply       54

 

That looks very hot. I don't particularly hear the fan but I can see the rpm is 2183rpm.

 

In fact - here is a piccy from the Photo Stream.

    Just to be clear:

     

    Are you sure these are "C"-Celsius temperatures or can these be Fahrenheit ?

     

    I'm asking because an Ambient temp of 60° Celsius is very unlikely.

     

    If indeed Fahrenheit, then the Temps are absolutely normal.

    Good eye Stefan, that beats Death Valley's record high by 3〫Celsius.

    Mostly because right now my Ambient is shown as 16° C

    Something is amiss here.  If those CPU temps are accurate,

    the fan should be screaming at around 4k RPM or more.

    Some other readings there make me wonder if the software

    has been updated for the current Mini.

    The chip is rated to 100 degrees C. If you get to 90 degrees C, the fan sound should be quite noticeable.

    Many many many messages are posted in the Mac forums with people thinking the 2011 machines are running "too hot". Well, they ARE hotter than previous machines as the chips from Intel run hotter. So, by itself, this means nothning and is perfectly normal  and expected. Intel chips heat room practiocally. ;-)

     

    The case gets hot, that also is normal. Some people also load fan controls, and, mis-set them, I find the defaults just fine. I have 100% cpu processes that run all night long on a 2011 server and it survives just fine. Not an issue.

     

    What is typically not normal is to be above 90 C and not hear audible fan noise. I would also thibnk the fan should be at 4000 rpm or so. I presume this is a Lion machine?

    I don't see a problem myself. Lots of 2011 machines hit 90 C. They just don't stay there for long at all! The temp that matters is the proximity temp, and that can go higher than the 79 being reported (up to around 90 for a very short time when the fans really kick in). I didn't look carefully the first time I saw your post and thought your proximity temp was 94. Sorry. So, 79 and fan speed of 2,000 or so is not unexpected at all.

     

    There is so much time being wasted unfortunately as you saw on other posts with people worrying about these temps. That only serves to make more people worry, etc. The reality is each new CPU from Intel runs hotter and hotter.

    Apart from keeping an eye on the temps I think you should run the Apple Hardware Test http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35727.html to ensure that everything is ok.

     

    Also, although meant to get high-speed running fans down a SMC-reset Intel-based Macs: Resetting the System Management Controller (SMC) might be advisable.
