I've been researching graphite pads as a potential replacement for thermal paste for my laptop, and I saw that every single application out there just dump the pad straight on the die/IHS.

From what I understand TIM were used to fill in microscopic holes on the surface of the IHS/die and cooler, so realistically don't you also need TIM between the pad and the 2 surfaces?

No, do not use tim. Also some Graphite pads are compressible.

Please be aware, these are not recommended to be reused.

no tim. you get a pad designed for this, like those^^, that squishes to fill "holes". then you cut it to size and put it on.

Who said they cant be reused? from what i can tell they last pretty much forever. I might not use them in different applications but sooner or later i will throw my cooler and fans under the faucet and make them new clean again. (or that was the plan)

Their are different kinds of graphite pads. You have highly compressible. You can get the standard which only compress's slightly. The one I linked is highly compressible. On the package it says not to reuse them. I've also tried to reuse them, they don't decompress. So the mating may not be perfect.

I used it on my r9 fury, which had uneven hbm.

I've read around and even the standard ones can only withstand about 20 applications before being too compressed to function well.

Does the highly compressed version perform better for you?

In my case it did. Because I had an r9 fury, the hbm is a bit offset from the die. So it gave me additional flexibility. You see even though the core temps were good it would still throttle. When I used the highly compressible stuff, it didn't have that problem. I think the memory might have been overheating.

Did you cut a big piece for the whole die or 1 for main die and 4 for the HBM modules?
