The Phanteks PH-TC14PE falls slightly short of the 60C delta barrier but it still remains in a position to compete with the Prolimatech Megahalem, Noctua NH-C14 and more budget oriented tower heatsinks. The delta of 60.5C is comparable to the PH-TC14PE working passively, an approving nod to the sheer efficiency of the latter. Having the fans on the PH-TC14CS reversed puts the Phanteks on par with the Thermalright Silver Arrow running passively. The same is true when two Noctua NF-P14s are used. With a single fan either in low profile or high clearance mode, or two fans at lower RPM, the Phanteks cooler is more competitive with smaller tower heatsinks rather than high end ones. Reverse mode on the PH-TC14CS produce 1.75C lower temperatures than the Noctua NH-C14 in the same configuration, albeit with different fans. Similarly, reduced fan speeds on the Phanteks also prove to be a slightly better solution to the Noctua also running its fans at lower RPM. Although high clearance mode is more effective on the Noctua, low profile mode demonstrates the opposite with a similar margin between the two coolers.
