I'm giving you a hard time. But yeah, all of the Intel TIMs have been wax-based, for quite some time. That's why they are dry and chalky; it's not candle wax... but it IS a wax base. It makes them very hard to spread and also hard to remove properly, because the wax fills in the valleys in the metal and tends to fill those spaces more than the actual "working" TIM particles do, but this also ensures that there is far better contact than you'd think there was.It wasn't waxy. It was an absolutely completely unusable powder that literally had trouble exiting the tube.
This isn't me making any overreaching claims either. It's one personal ancedote. Take it as nothing more. (The rest of the composition comments were me kidding around).
It is also why Intel heatsinks have such a high clamping pressure. Grease-based TIMs do not need such a high clamping pressure. Intel's documentation (platform whitepapers) have mentioned exactly this as to why the clamping force of a heatsink needs to meet minimum requirements, and why heatsink makers should be sure that the clamping force remains after long usage periods, since there will be some loss of the clamping force due to heat stressing. I mean, think of all those stock heatsinks that curve a motherboard... they clamp so tightly because Intel uses a wax-base TIM!!! Intel has designed their heatsinks purposefully for that chaulky TIM!!! The high clamping force makes that type of TIM perform better!
