No, the mysterious “Gaming Paste A” from the basic article is not the KINGPIN Cooling KPx, I’ll solve that mystery next time. And where some manufacturers give too much data, there are no official data sheets for this paste at all. The paste, especially the supporting matrix, was developed for use with liquid nitrogen and is therefore particularly suitable for use on special LN2 benchtables. Unfortunately, you often see users who also use this paste in normal PCs, although the purpose of this paste is completely different. However, this should be made clear to the customer, but it is not. And so many customers buy a paste that the marketing department is sure to love and which also costs a lot of money. The only problem is the performance under normal living conditions. But what the heck, the color is so nice and cool…
What you can attest to with the KPx, however, is its solid foundation, which I’ll come to later. As with our reference paste, it’s not primarily about the last degree for the user benchmark for the longest bar in the home PC, but about professional low-temperature behavior without cracks during extreme overclocking with LN2. The paste is a safe bet for this special purpose and for normal everyday use? We’ll find out in a moment, because it’s not as if it wouldn’t work at 20 °C and above. The only question is how long.
Even if the following quote comes from another manufacturer, I simply have to emphasize that Arctic is the only manufacturer to date that explains the values for thermal conductivity correctly or does not even embellish them. The FAQ on the Arctic homepage is therefore generally worth quoting in full, as it not only speaks to me from the heart, but is also absolutely consistent with my laboratory measurements. Much more than 4 W/(m-K) is not possible at all with conventional pastes. Because it is so beautifully honest, I will use this part from now on as a standard quote in all paste tests of all manufacturers and place it in front.
Why does ARCTIC not communicate any values for thermal conductivity?
ARCTIC has deliberately decided not to specify any values for the thermal conductivity of thermal pastes and thermal pads, as many manufacturers invent, artificially inflate or embellish this value. Thermally conductive paste has a thermal conductivity of 1 to 4 W/mK. Values outside this range, such as 12.5 W/mK, do not correspond to the truth. Many competitors state values above 4 W/mK to suggest better performance. This often leads to false expectations and dissatisfied users. ARCTIC offers its customers innovative thermal conductive materials at the best possible price-performance ratio instead of relying on manipulated performance data.

Unboxing
There’s not really much to write about here, because apart from a spatula, there’s nothing else in the plastic bag my 10 gram tube. But that’s enough, I have liters of isopropanol.
Technical data
Let’s leave the marketing aside and look at the technical data of this paste, which is available in various containers and sizes. We can see that the information on thermal conductivity has nothing to do with reality. The green shaded columns contain measured values, the gray shaded columns contain the completely missing manufacturer’s data
