Compare: NH-D15 chromax.Black vs NH-L9x65

Design and Aesthetics:

NH-D15 chromax.Black

The NH-D15 chromax.Black features a dual-tower design with two large aluminum heatsinks and a pair of Noctua's 140mm NF-A15 PWM fans. The cooler's design allows for superior heat dissipation, making it capable of handling even the most demanding processors. Aesthetically, this version of the NH-D15 adopts a black color scheme, providing a sleek and modern appearance that complements various build themes.

NH-L9x65

The NH-L9x65 features a low-profile design with a slim aluminum heatsink and a 92mm NF-A9x14 PWM fan. With a height of only 65mm, the cooler is compatible with a wide range of PC cases, including mini-ITX and HTPC builds. Aesthetically, the NH-L9x65 maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

Install Notes:

The NH-D15 features Noctua's SecuFirm2 mounting system, ensuring compatibility with numerous Intel and AMD sockets. The installation process is made easy with the help of clear instructions and top-notch components. Additionally, Noctua includes a tube of their high-quality NT-H1 thermal compound for optimal heat transfer between the CPU and heatsink. However, the cooler's large size may make it challenging to maneuver around when installed within the case.

NH-L9x65

This cooler is designed to be a typical Noctua cooler installation, which is easy to do and rather straightforward. This means that if you're new to installing a CPU cooler, there is little room to make a mistake. For AMD is uses the original AMD backplate. Only downside to the Noctua installation is that the cooler may stick to your CPU and given how the screws are setup, you can't slide the cooler off the CPU like other brands.

Cooling Performance:

The performance of the NH-D15 is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, from mainstream CPUs to high-end models with high TDPs. The cooler can handle high levels of overclocking and provides reliable cooling under demanding situations, making it a popular choice among enthusiasts. If this cooler can't handle the CPU's heat, then you will have to move to AIO coolers.

NH-L9x65

The performance of the NH-L9x65 is suitable for most mainstream CPUs and everyday tasks. It has four heat pipes that efficiently transfer heat away from the CPU to the heatsink. While the cooler may not be the best choice for high-end CPUs with high TDPs or extreme overclocking scenarios, it provides adequate cooling for lower TDP CPUs, especially in small form factor builds with limited space.

Noise Performance:

One of the standout features of the NH-D15 is its quiet operation relative to its performance. The two included 140mm NF-A15 PWM fans are designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15 is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions. Additionally, the Low-Noise Adaptors (LNA) connectors included can be used to reduce the fan's speed, further reducing the cooler's noise.

The 92mm NF-A9x14 PWM fan included with the NH-L9x65 is designed for quiet operation while maintaining good airflow for its size. Noctua fans are well-known for their excellent acoustic performance, and the NH-L9x65 is no exception. Users can expect quiet cooling even during low workloads, however due to it's limited cooling abilities, it may have to run louder moderate workloads or gaming sessions.

Summary:

NH-D15 chromax.Black

The NH-D15 cooler offers easy installation with Noctua's SecuFirm2 mounting system, compatibility with numerous Intel and AMD sockets, and high-quality components. Featuring a dual-tower design, two large aluminum heatsinks, and a pair of 140mm NF-A15 PWM fans, it provides exceptional performance and heat dissipation for a wide range of processors, including high-end models with high TDPs. The NH-D15 chromax.Black version boasts a sleek black color scheme, and despite its large size, the cooler operates quietly during intense workloads or gaming sessions, with Low-Noise Adaptors available for further noise reduction.

NH-L9x65

The Noctua NH-L9x65 is a compact and efficient air cooler that's well-suited for small form factor builds and systems with limited space. Its low-profile design, adequate cooling performance, and quiet operation make it an attractive option for those looking for a space-saving and reliable cooling solution.
