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.

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.

Hi, I've checked the temps - they are in Celsius
I'm also wondering if they reflect the real temp. I would also think that the Mac fan would be going crazy and 94 is almost boiling. My Mac isn't that hot to the touch. From what I've read, I think you'd notice the Mac fan making a chunk of noise. I've not heard much noise so I can't see the CPU was really that hot.
My Mac started to become very slow.
Mail stopped responding.
I've rebooted and my temps are slowly coming down. I've also noticed my watts was previously 34.52W but is now 12.75W
Does anyone know what could have caused this? Mail stopped responding - could this have caused the high temps?

Right, it's been a bit of time since re-boot and my Mac CPU is 50 degress C. I suspect that something somewhere crashed in Lion (10.7.2). I had a problem with Mail. The Mac wouldn't shut down due to Mail cancelling the operation. I then tried to select quit from the menu but it was greyed out. I then had to force quit but I've also been playing with cloud services earlier on (which are great btw). I noticed that a 'Guest' account appeared from out of no-where next to my user account. I don't know if any of these things contributed to the high temperatures but will monitor my software usage in relation to this in the future.

There was hardly any fan sound but the case was hot, not burning but it was hot. After the re-start it is cool. The fan didn't kick in but I'm wondering if this was due to a software crash?

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?

Hi, yes this is a Lion machine. I think that is my main concern as well.
The machine ran very hot and no fans kicked in which either means that my temperature monitoring software was incorrect or the Mac stood for awhile cooking without the fans kicking in. I fear it is the latter.
I understand about cooling (being one of the unlucky ones who had a broken liquid cooled quad 2.5 Power Mac) and only installed the Mac Mini temperature monitor when I became concerned that the mac was running way to hot. During the days I've owned the mini, this was majorly different. I also have a quad core Intel Mac Pro in the same room to compare it to.
Then I saw the temps and felt the heat from the back vent. I knew this wasn't normal. It was running at this heat without anything open or any underlying system operations running in the background.
I've decided to phone Apple. I'll see how the Mac Mini fairs but I don't like the thought of it cooking at 94C for so long.

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.
