Fin, There is one bit of engineering you may not have considered. 72C is an ambient across the die temperature, as they are for the P3 and the K7. However, while the architecture of the P3 and K7 are quite similar in many ways, the P4 has an interesting wrinkle that you may not have considered: the 2X clock ALU's. What if the P4 die has "hot spots" that are out of the norm for previous generation microprocessors requiring a lower average temperature to provide margin for those to run at 80C, 90C, or higher? Exactly my long standing point about P4. The double speed ALU causes all kinds of problems with heat and scalability. Thanks for backing me up. Scumbria
