Make no mistake, Noctua makes some of the best performing air coolers we have ever tested. The NH-D14 is widely recognized as the best dual tower CPU cooler money can buy. However in our open bench tests, the single tower NH-U14S actually outperformed it. This was acknowledged by Noctua, and they suggested that the new heatpipe design is what was responsible for the outstanding performance of the NH-U14S.
We pondered what would happen if that improved heatpipe was combined with the dual tower setup of the D series cooler. Buyers will be able to find out now, as the NH-D15 is announced, and ready to hit store shelves this month.
The NH-D15 features some other improvements over the D14; as you can guess by the name, it is 15cm wide, and can accommodate Noctua’s NF-A15 PWM fans. This also allows the new heatpipes to be spaced further apart, which improves heat dispersal over the larger area. Finally, the lower fins are recessed, allowing RAM with heatsinks up to 64mm tall. The fan can simply be installed as high as it needs to, to accommodate any size RAM module.
We hope to have a review up soon; for now you can check out Noctua’s video comparing the NH-D14 to the NH-D15 as well as their product page for more details.
