While it is possible to help keep things cooler by putting the processor to sleep in the idle loop (which FreeBSD does on non-SMP systems), that alone is not a solution to a thermal problem. If your system were under heavy load (and if it isn't, WHY do you have an SMP system in the first place?), you would have exactly the same problem no matter which operating system you used, since the processor would not be put to sleep very often. Your only solution is to fix the problem the right way, by providing more cooling. As a stopgap measure until you either stick the thing inside a refrigerator or at least throw a few more fans in there, you can compile a non-SMP FreeBSD kernel and you will get the idle-loop "cooling" effect. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
