"With many years of experience in high performance, noise optimized cooling solutions hailed by many around the world, Noctua has yet another winner in their hands. The NH-D15 is built upon the successful NH-D14, a mega sized heatsink that represents the epitome of cutting edge air cooling technology. Now with improved aerodynamics first seen in the NH-U14S and NH-U12S, combined with the latest NF-A15 fan, it is easy to see why the NH-D15 is such a successful performer on our charts once again."
