Our chart is very competitive at the top and yet the K2 finds no problem competing fitting in amongst the best. The default K2 setup provides performance to match the likes of the Thermalright Silver Arrow and Corsair H100 with fans at 2600RPM. Switching to two Föhn 120s improves performance by 0.5C which is enough to put the K2 on par with the Venomous X using two Coolink fans and the Silver Arrow using three TR TY-140s. With a single 140mm fan, the K2 matches the Super Mega with two much higher RPM Coolink fans but is left slightly behind the Silver Arrow also using a single fan setup. At reduced fan speed, the K2 matches the Archon and outperforms the likes of the NZXT Havik. The best performance comes from the two Coolink fans which allow the K2 to match the NH-D14 using the same fans and also outperform the default Phanteks setup. Not far behind is the K2 and three NF-P14s.
