Control curves in the TIMA analysis
Before I go into the actual values of the individual results, I’ll present the originals from the TIMA software, because it’s also a question of transparency. Especially as we are also shown the bulk thermal conductivity here, which was determined for the relevant temperature and BLT range. In the data interface, you can check these real determined values in advance, test them for plausibility and deselect the deviating values for the determination. In this way, you can also recognize the slight anomalies that may exist at certain layer thicknesses, where the thermal resistance no longer correlates particularly linearly with the layer thickness.
But this is exactly what you have to question, because there must be reasons for this. In addition, the correct bulk thermal conductivity is given here exactly as it is determined by the reputable manufacturers. Depending on the linearity, I use a minimum of 10 and a maximum of 16 individual measuring points for the overall result. The fair weather analyses, on the other hand, are based on measurements in a bucket with a minimum distance of 10 cm or only two very closely spaced measuring points (BLT). Then you can quickly get over 10 W/m-K or more.
Cooler Master CryoFuze 7
This paste performs very well and, at almost 4.6 W/m-K, also offers by far the best performance of all four Cooler Master pastes tested. The bulk value catapults it into the upper class, although it still falls short of the magical five before the decimal point in the top class. The interface resistance of 5.4 mm²-K/W is also pleasantly low.
Cooler Master CryoFuze 5 Violet
With a bulk thermal conductivity of 2.6 W/m-K, this paste performs the worst, which is surprising because the price and packaging imprint imply a higher performance. But if you really want to be honest, you can’t just make a nice calculation for this paste because it’s purple. It’s not even mid-range.
Cooler Master MasterGel Maker
And what does our gray wide-mouth frog achieve among the tubes? With 3.9 W/m-K, the paste falls short of the CryoFuze performance, but at least it almost reaches the upper class limit, which could be seen at 4 W/m-3K.
Cooler Master MasterGel Pro 2
At around 3.5 W/m-K, the paste is slightly behind the MasterGel Maker, but well ahead of the CryoFuze 5 Violet. This is a solid mid-range product and also fits the price.
