Hi,
I have a new MAC MINI 2 GHz. If I use SETI 2 processors with 100% CPU temperature is 83 degrees.
(With 50% t ° is 70 ° and without SETI t ° is 60 ° Is this mormal ?)
What do you think?
Thanks

logically, No

Did you install iStat?

Is your fan working?

83 is technically near 100 and boiling

Hope the temperature was in celsius, if not, man, should be cold out there

You can add a software to relax your CPU

Thanks for your help
-- The temperature is in Celsius
-- How to verify the fan? Mac mini makes no noise and Apple Hardware Test reports no problem
-- How to test the fan?

The Mac Mini is a tightly packed little box of Apple goodness. I've long suspected that it shares the same potential problems that lappie owners face - i.e. the cooling solution is just about adequate for normal running, but not the continuous load that SETI imposes.

You could limit your crunching to one cpu core by going to your account and adjusting your preferences. Or you could use the local BOINC preferences to limit cpu use. Either method should reduce the heat being generated.

Laptop users often employ laptop coolers to assist heat removal. Amazon stock lots of different ones, so I wonder if such a device might help a Mini keep its cool.

Ok, thank you for such information and advice.
I will think to find a balanced solution

For information. Here is my solution:

1 - Installing software "smcFanControl"
2 - Fan speed >>> 3500 tours
3 - Use SETI >>> 50%

Result: t° CPU is between 54 and 59 °

It's absolutely normal for the CPU temp of a Core 2 Duo Mac mini to run between 85 and 90ºC when crunching SETI. Nothing to worry about at all. I've been doing this for over a year on a number of these boxes without issue.

However, _do_ make sure that the air intake openings around the base of the unit can 'breathe' without restriction. If you place three equally spaced pencils (or something similar) under the unit to elevate it off the surface it's standing on, you can reduce CPU temp and fans speeds somewhat. Do make sure to use three spacers instead of just two at the edges, otherwise the bottom of the mini _will_ warp.

While it is true that minis use laptop-grade silicon and drives, this does not apply to its cooling system: it's way more beefy than anything you'd ever find in a laptop. The G4 minis have employed a very similar cooling system, and I've had G4 minis run on SETI more or less since the day they were introduced - again without any hiccups to date.

OK, Well received all information. Do everything necessary for cooling.
Thanks for your help

I recently installed CoolBook to change my MacBook's CPU voltage settings. Although this little tool is a bit tough to configure, although it cost me $10, I ended up with running SETI on 50% with the fan at it's lowest, when I should set it to under 30% in order to keep the fan from revving prior to installing CoolBook.

As I read elsewere, CoolBook work also on iMacs, although I never saw temperature issues on any iMac. I may work for MacMinis as well, but I can't say for sure...

What's more, after I carefully set CoolBook, I ended up with 8 hours of battery life on my MacBook! Plus; it's better for the environment as well, since my CoolBook tuned CPU now uses around 30% less energy (dropped from 1.25V to 1.035V on 2Ghz).

You could also use Fan Control which is a System Prefs pane, which would add it to the "Other" for the Prefs pane, you can download it here http://www.macupdate.com/info.php/id/23137
