...and the lack of air is an even better insulator.
The problem is that I don't know how powerful the suction is. Plus, It has to be reproducible, so I have to add a vacuum gauge, and see what the max suction is, then throttle it back a little (in case the pump fails, or wears). I'm just not sure I'm willing to go that route, yet.
I'm also stuck with the choice of the IHS. Without it, the die would be ~13 by 12mm (156 mm^2) (thanks to a tip that was PM'd to me), and should closely resemble/reproduce a P4 (square, 146 mm^2), and an Opteron (rectangular, ~164 mm^2).
(I still have to confirm all the dimensions above)
After Bill's comment (of which I was already aware), I'm thinking about dropping the IHS alltogether: I don't believe that the "heat spread" is significant enough to warrant all the extra effort. I believe that it would be a greater source of error to use an IHS. In my case, I was going to build a second heat die just for it.
pHaestus, where in the die are you going to place your temp probe? I'm tempted to reproduce the AMD spec for HSF.
