The results have been arranged in terms of the fan configuration that yields the best results for each cooler. However, it is important to take into account that many coolers come with their own fans and changing those increases the costs significantly, so the “out of the box” cooler configurations have been highlighted in red each group.

Compared to the old results, the K2 has moved up two positions. Let’s start by looking at the different fan configurations. The default setup gives a delta temperature of 30C, same as with two NF-P14s or two Föhn 120s. Opting for a third 140mm Noctua fan reduces temperatures by 0.75C whereas using a single Föhn 140 increases the delta by a mere 1C. The second best configuration, not surprisingly, is through two high RPM Coolink fans. Impressively, even with the fan speeds at 60%, the delta is 31.75C, not a significant drop from the default K2 setup. Passively, the temperature delta is 35.75C.
