Surface analysis
Now we come to the GPU and the thermal paste. The application may have been full-surface at the beginning, but after only a few months there is nothing left to see. The inferior paste has dissolved into its components. Or rather: the actual matrix of the paste no longer exists and the silicone has evaporated (so-called bleeding).
What remains is an inhomogeneous surface, with even the remaining residue still pulling threads because it is dripping with silicone. I analyzed the whole thing again in high resolution with my Keyence microscope and let the built-in AI calculate the area that was not (or no longer) covered with suitable thermal paste. The figure is downright frightening, as over 35% of the surface area is affected. This is downright depressing and now also explains why the hotspot temperature ended up well above the 100-degree mark.
The fact that the map cannot work like this is certainly beyond discussion. It just doesn’t work that way. But I’m a fair person, so I did a cross-check with the cooler, because it could be that the missing paste on the GPU sticks to the bottom of the cooler. But the high-resolution photo shows that this is not the case, so you don’t even have to measure it. If you put together the mirror-inverted impression here in your mind’s eye, then you can only be shocked, because it fits:
Let’s try the AI’s surface and shape recognition again and see that there are only a few deviations in the decimal place range. Here, too, there is well over 35% uncovered area. What had to be proven:
Material analysis
Such a cheap piece of junk doesn’t belong on any graphics card, not even on an extra cheap one. Except that we are already in the upper price segment here. This makes the accusation all the more serious. I also examined the material of the board and the laser spectroscopy confirmed once again that a few fillers such as corundum and zinc oxide were literally mixed with far too much silicone. You simply shouldn’t use something like this, it’s almost planned obsolescence, or at best, misunderstood cost savings. It’s not even 45% solids, the rest is silicone. It’s not even paste, it’s soup.
And because I already had the card open anyway, the thermal pads are also included. Whether VRM or memory, same thickness, same content. With a proportion of thermally conductive fillers of over 40%, the pads are average middle class, especially as they are still not oiled even after months. After the “scandal” I uncovered at the time, the manufacturers have at least made improvements across all companies. At this point, I would like to see the same for the thermal paste and another “nudge” from NVIDIA when the controlling department is being stubborn again because the boss’s wife needs a new fur coat. After all, the “voluntary rethinking” of the pads was no coincidence at the time.
The bottom line is that you can neither accept nor understand something like this, but at least you can fix it. And that’s exactly what you can read on the next and last page.
