<..that they can actually work with that low a Tj is a testimony to the low power dissipation of the PIII> Not necessary. Tj is a function of power dissipation _AND_ size of heat sink. Any power can be countered with bigger and better heat sink. That is what P-III systems do to survive. See example, from an optimist: Message 14917027 BTW, I found it interesting that all P-III stepping cC0, starting even from 550MHz, have Vcc of 1.70V. I guess our Intel's reliability experts like Elmer, Paul and Tony, have full explanation for this. - Ali

Fyo, However, that they can actually work with that low a Tj is a testimony to the low power dissipation of the PIII (which is a good thing). I think you are mixing 2 things: Tj and power dissipation. Actual temperature of the CPU is a function of power dissipation of the processor and the quality / parameters of the heatsink. Max Tj is just a ceiling of beyond which the CPU may not operate reliably. I can't see how anybody can argue that low ceiling is good. Joe
