The K2 now compared even more favourably against its competitors. The three setups yielding a delta of 30C and coupled with the Coolink fans producing a delta of 29.75C, performance proves superior to the default Noctua NH-D14 and the Thermalright Silver Arrow. Only the much louder ALC units with fans above 2000RPM and the Phanteks with three fans are able to outperform the K2. With three NF-P14s, the K2 ranks fourth on our extensive list! The single fan on the K2 is able to match the likes of the Corsair H100 with 4 fans at 1300RPM and manages to even outperform the Thermalright Silver Arrow. At 60% fan speed, the results are still enough to match the Zero Infinity Free Flow+ and outperform the Phanteks also with lowered fan speed. The main difference is that the Föhn 120 and Föhn 140 still operated at 1000RPM and 800RPM respectively, higher than the Phanteks’s fan speeds. Finally, we see that passive performance is enough to beat the popular Antec KUHLER 620.
