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.

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.

I've very little experience with computers in racks, but if the machines are actually touching, then yes, this could be the case. The 65 C temperature a previous poster was talking about is not the maximum operating temperature for the actual processor, it's the maximum temperature in the case while the computer is operating. As far as I know CPU temperatures are measured on the actual processor die, and the case temperature will normally be *much* lower.

Re: coretemp 70C = CPU too hot?
As with so many other things in the computer world, it depends. With no case fans, it's weird that the computer gets colder if it has something above and no it's not. the machines above and below has proper cooling, and transfers this machine heat by conduction - rack cases are mostly metal and conduct heat well. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

The CPU is a Xeon 3xxx dual core 2.4 GHz.

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.

With no case fans, it's weird that the computer gets colder if it has something above and underneath it. But there are so many factors when it comes to case temperatures and air flow that it's nearly impossible to tell why. If there's a huge cooler on top of the Xeon (Processor wind tunnel), then it could be that closing the ventilation holes in the top and bottom of the case makes the air flow more directly from the front to the back of the case. It seems the Xeon shuts down the system automatically if it reaches 105 C. I don't know if this is any pointer to what a reasonable 100% load-temperature could be, but I know processors nowadays run much cooler than they used to. (I'm used to AMD Athlons on or above 70 C idle) I'd say you should be fine if you haven't seen any instability at 70 C with 100% load.

coretemp 70C = CPU too hot?
Howdy. I purchased a 1U 10 inch deep server machine a few months ago: http://www.abmx.com/1u-10inch-deep-supermicro-mini-server-p-366.html?osCsid=80f3951929d5a7ae27a51733627ee18a The CPU is a Xeon 3xxx dual core 2.4 GHz. The machine has no case fans, by design. It's sitting in a well-ventilated rack in a data center. Oddly, when there are no machines below and above it, the machine gets hotter. Seems that machines above and below help to cool it down. I have the "coretemp" kernel module loaded on the FreeBSD 7.0 OS, and I saw that the CPU core temp(s) hit 70 degrees Celsius during a compile of GCC. Is this too hot? Should I complain to the people who assembled the computer? At the time this happened there were supposedly no surrounding machines. This machine has given me no problems. At idle when conditions are good (meaning A/C is working properly and there are machines above and below it) my CPU temps are below 40. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
