Although the machine in question has been heavily loaded in the past (as someone pointed out, why else have an SMP machine?), I've never seen these processors reach 70 celcius before. Under Linux, I would expect them to get to around 50 degrees during busy periods, but don't run distributed net clients, etc. That would get things a little hotter. I've invested in coolers and feel that the machine has adequate, if not exactly excellent cooling. There are one or two constraints on this which I cannot control. With that in mind, is it fair to ask for support of SMP systems to change at some point to include the instructions to run the chips cooler? I note the comment on temperature stability, but I think my mileage is varying.
