Noctua NH-D15 CPU Cooler Review

Cooling solutions come in all shapes and sizes but the dual-tower design is a very distinct model that is mostly associated with the extremely popular Noctua NH-D14. There may be CPU coolers with dual tower designs that came before it but the NH-D14, with its saw-tooth aluminum fin radiators and uniquely colored Noctua fans is an enthusiast favorite for its excellent heat management while operating fans that are not distractingly loud. The NH-D14 however is several years old now, so like most of other PC related components, it is due for an upgrade.

Noctua NH-D15 Installed

The Noctua NH-D15 replaces the massively successful NH-D14 as Noctua’s flagship CPU cooler offering, moving towards a more efficient design and equipped with a pair of Noctua’s latest NF-A15 fans. Users with tall RAM heatspreaders will also be delighted by the fact that RAM compatibility has been taken into account in designing the NH-D15, moving the lower fin stack to provide 64mm of clearance for the first and second DIMM slot when installed. The NH-D15 is available with an MSRP of $99 USD and carries a 6-year warranty covering the heatsink build, accessories and fans.
