What have we learned today? Both expensive pastes contain virtually the same ingredients. And no, they are not diamond-enhanced high-performance ingredients, but rather plain corundum, i.e. Al₂O₃. To prevent the round grains from to much air outside, cheap ZnO has been added to both pastes, i.e. the usual zinc oxide. Of course, both also have a little quartz sand as a tiny impurity, which can hardly be avoided. And now?
If we look at the results of the mechanical comminution, we see minor differences, which are probably due to the tool. From this point of view, the starting materials are the same but not completely identical in the way they are produced and the traces that are created. Which actually almost rules out the possibility that the base material here came from the same barrel from a common manufacturer. If you look at the relevant tests and reviews, you should always keep in mind that the base of both pastes is almost the same. See picture.
There could still be differences in the silicones used, but there we also have to pass. Therefore, my call to the community and the question of whether someone there can and would like to help in this regard. For other differences, even in the rather difficult processing, can not be found between these two pastes. If someone should notice different measured values, then it is certainly also due to one’s own skills to achieve the same surfaces. I once ran the pastes in a nightly GPU cooler retest – there were no deltas outside the calculated tolerance limits.
And what does that tell us now? Who does not care about the price, just buy by color. Pink vs. blue is certainly worth a lively discussion as well. Only these, unfortunately, can not be decided with one measurement. This happens in the mind of the buyer.
