89W is the TDP (thermal design power) for a prescott, NOT the actual heat output. It's a number Intel calculated to give heatsink manufacturers a maximum number to aim for. Using it as a basis for actual output is highly suspicious. Vcore*Imax is probably a better number, but still dubious - not all that power goes out the top of the core. Besides which it's virtually impossible to drive a CPU hard enough to hit Imax outside of lab testing.
