Sony Chemical & Information Device Corp exhibited a prototype of a sheet whose thermal conductivity is equivalent to that of thermal grease ...

Neat. But the chances of seeing 2 cpus at the same temperature is kind of rare.

I take it that's the sound of something going over my head?

3 degrees can be made up by so many factors.

I'd rather see a before and after because the randomness with different CPUs and mountings is just too much. Better yet a regulated 50w source and an accurate temperature probe with long term data. I'd give it much more credence.

I don't have problem believing that it is better than stuff they use normally, but it is nowhere near the "enthusiast" class TIM we use, like AS5, NT-H1 etc.

I think the advantage is that it lasts longer than traditional TIM. Could be very good for consumer applications like tablets, TVs, etc. where you want longevity and generally do not replace the TIM.

Exactly, the typical "out of factory, never going to be opened" stuff, where they use some el cheapo but long lasting TIM, the same that Intel uses with IB.

But, what about all the tiny imperfections in heatsink bases? All those microscopic pits and gaps?

The high thermal conductivity was realized by using silicon highly-filled with carbon fibers

Damn it, when will people learn the difference between silicon and silicone. I very much doubt this thermal interface material is silicon.

You mean.... they're not both white?

On the flip-side, the irony is not lost on the fact that a solid silicon matrix (not silicone) containing carbon nanotubes oriented parallel to the direction of desired heat-flow would actually be quite a fantastic thermal conductor sheet. Fantastically expensive too, but fantastically effective nonetheless
