" less.....don't you mean more? At least thats how Pentiums are...the smaller technology=more heat."
That's because Intel screwed up their Prescott cores that leaked causing it to run extremely hot. AMD 64 90nm's however run like they were meant to.
As for your question Aj2003 I'm not sure about flashing the BIOS to get the mobo to recognize 90nm cpu I'm sure someone here can answer that.
