"Perhaps testing should move to tying into the P4 readable diode and using the 775 as the testbed for IHS based CPU's as for one, the TIM is far better and 2, it is not removeable. Leave the AMD for IHS-less tests."

reasonable to me
with both bare and clad, W is not known but guesstimated (on basis whatever)
- for bare (AMD only), C is based on pH's diode reader ?
open source ? technical skill req ? cost ? (does procooling care if ph's bench is unique ?)
- for 775s, C is based on the TC reading of the grooved IHS
open source dwg and procedure ? skill ? cost ? (does procooling wish/intend doing 775 based testing ?)
-> why not ? (want more readers ?)

The heat die sim seems more problematical, what now needs to be recognized is that a good die sim is far more than the slug I began with. To derive a non-intrusive face temp requires a sophisticated design with excellent equipment and procedures, a commitment of time and resources. Ice Czar is perhaps the only possibility for such a device that I am aware of, inclined to test commercial products.
peeps wanting a good die sim should be really nice to IC
