You can look up the thermal specification on Intel's web site: http://processorfinder.intel.com Looks like most of the 2.4 GHz Xeons' maximum operating temperature is 65C, but one of them is 85C. So let's hope you have that particular part (the X3220). :) Anyway, that should confirm whether it is too hot or not.

As with so many other things in the computer world, it depends.

Re: coretemp 70C = CPU too hot?
Also something to keep in mind, most (all?) new procs have thermal cuttoffs that will kill themselves before any damage happens. If you box hasn't shut down in weird ways or underclocked itself, you are probably good to go. It's something to keep your eye on, but I wouldn't worry too much about it if you aren't experiencing any problems.

Re: coretemp 70C = CPU too hot?
Thanks for all the replies guys. I called the manufacturer and it turns out that there's a manual speed controller on the CPU fan. I'm going to take the top off my case and crank it up all the way at my first opportunity. That will at least help a little bit. Thanks again. I still think 70 Celcius is too high.
