Noctua NH-D14 Vs Noctua NH-D15 CPU Coolers Comparison

Premium performance and smooth running of any computer is the desire for many owners. To achieve this, effective and efficient hardware and software to run it are pre-requisites. Key to achieve efficiency is the ability of the computer to run on incredibly low temperatures even at optimum operation.

A top-notch cooling system is therefore vital, and the solution can be found in Noctua’s NH-D14 and its successor NH-D15 that provide the anesthetic feeling of owning a super performing computer at costs that are overridden by the output.

NH-D14 VS NH-D15 Compared

NH-D14 Review

Manufactured in 2009, the Noctua NH-D14 tandem tower heatsink has the reputation of being a better cooler as the temperatures increase, enhancing efficiency.

NH-D14 Design - How does it compare with NH-D15

By design, NH-D14 is easy to assemble.  It has two fans mounted on using two-wire clips each that are easier to attach and remove in a uniform way. Further, it has rubber strips that act as silencers, dampening vibration, and reducing mechanical noise during operation. NH-D14 is designed with jagged zig-zag edges over a flat plane that maximizes its ability to permit airflow between the fins with minimal resistance and turbulence noise.

NH-D14 size provides a massive surface area for heat dissipation, hence lower processor heat levels even at maximum speed. Its 2-2.7 pounds does not significantly increase the weight of the computer and pressure of the motherboard.

NH-D14 Efficiency 

By design, NH-D14 has copper/aluminum hybrid heatsink electroplated with nickel. Copper, which is an excellent heat conductor, is used in the heat pipes coated with a thin layer of nickel, to withstand corrosive environments with high temperatures. Nickel's ductility and toughness diminishes NH-D14 loss of cooling performance over time, hence enhancing its durability. It comes along with IC Diamond paste.

NH-D14 Cost

NH-D15 costs around $80

NH-D15 Review - How does it compare with NH-D14

This is a 2018 upgrade of NH-D14 that has taken care of some of the flaws, improving performance and ease of assembly.

NH-D15 Design

NH-D15 is designed with a hybrid approach in the heatsink fin leading edges, characterized by a low angle V-shaped slope towards the center and bits of smooth zig-zag edges, unlike NH-D14. This maximizes its ability to permit airflow between the fins with minimal resistance and noise. It is more less the same size as NH-D14 but weighs between 2.2 and 2.7 pounds when fully assembled. Once installed, it provides a bigger RAM clearance.

NH-D15 Efficiency

Like its predecessor, NH-D15 has copper/aluminum hybrid heatsink electroplated with nickel, enhancing cooling and durability. It has two easier to mount and dismount spectacular NF-A15 PWM fans that spin up to 1560 rpm compared to the NH-D14 that spins up to 1300 rpm.

In addition, it has a widened heatsink as well as increased distance between the heat pipes for higher cooling performance. The NH-D15 comes with two RC-7 Low Noise Adapters so that the heatsink can run silently. It also comes with a Y-Cable and a tube of NT-H1 TIM.

NH-D15 Cost

With its efficient top-tier cooling capability, NH-D15 costs around $90


In a nutshell, computer enthusiasts would find themselves torn between the two premium models were it not for the NH-D15’s asymmetrical design that provides more clearance towards the PCle slot, superior RAM clearance and its performance that can provide 33.8-37.4°F better performance.

This notwithstanding, investing in either of the two would provide an awe moment in computing.
