My own observations show that FreeBSD does a much better job of keeping the CPU cool than Windows does. I have no scientific data here, but on my brother's K6-2 500 Mhz, the mainboard only switches on the fan once the CPU has reached a certain temperature. In FreeBSD, the fan basically stays off if you boot and do nothing. Only if you produce some serious load (make world, etc) the fan will come on. If you let the system sit idle for some time, the fan will even go off again. In Windows, well, you just have to boot it and let is sit "idle" for a few minutes. The fan will come on and never go out again. This seems to suggest that Windows does something to the CPU even when it seems to do nothing. Generally, as far as cooling is concerned, I have found it useful to follow AMD's recommendations, which say that besides a PSU and CPU fan, you should also use another rear exhaust fan. This may make your machine a little noisier, but it could be essential, especially if you have other things in there that produce a lot of heat (like a fast hard disk, graphics card or whatever).
