Hello,
So it seems Asus is using some kind of thermal pad for Fiji GPU core in R9 Fury Strix cards. The heatsink is not touching GPU die and HBM memory evenly - so that is a reason why thermal pad was used.
This has to be very high end thermal pad. The amount of Gelid GC-Extreme thermal paste I had to put to make sure 100% of the die and memory were making contact with the heatsink, results in +10C temps or more.
Does anyone know what is it and where to get it or something similar. It is about 0.5mm thick.

The best I found is Laird TPCM 920 0,51mm thick. No idea if this stuff is appropriate for 250W+ card... If the numbers are legit and its 2 W/mK - that is 8 times worse than Fujipoly XR-m...
