Let’s start with the thermal paste on the GPU, which is actually a pad. After the phase change, a hardened mass of predominantly finely ground corundum (Al2O3) and even finer zinc oxide (ZnO) remains as a gap filler. This type of phase change material is long-term stable and better than most commercially available thermal conductive pastes.
The copper heatsink of the GPU does not pose any puzzles, it is clean electrolysis copper without extra polishing. The tool marks of the milling machine are clearly visible even at 300x magnification.
The pads between the heatsink and VRAM as well as the one on the voltage converters are ok and consist of slightly more viscous silicone, as well as corundum and zinc oxide as a thermal filler.
The slightly thinner pad on the coils looks almost identical, but is much harder. Here I have removed the oxygen and hydrogen components, which ultimately indicates the same composition as the storage pad if you add up the atomic weights of the remaining solids.
The inner mounting frame also serves as a heat sink for the voltage converters and is made of nickel-plated aluminum.
The heatpipes are also nothing new, we see an electroplated nickel layer on the heatpipes made of pure electrolysis copper,
The backplate is made of lightly anodized aluminium and not an alloy.
The GPU clamping cross is interesting because the spring steel has been galvanized for a very long time. The colors and structures are almost like modern art.
Here we continue with the “deep drilling”, which took almost forever until I came across pure iron.
There’s nothing more to report here. Of course, I did all the measurements and all the benchmarks of all the games before disassembling, because anything else would be pointless. And that would be an elegant transition to the next topic.
