Compare: NH-D15 vs Mugen 6

Design and Aesthetics:

NH-D15

The NH-D15 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 maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

Mugen 6

This cooler features a sleek, monolithic design with an exposed metal heatsink and a polished top that conceals the heat-pipe ends, giving it a clean, refined appearance. It comes with a single 120mm black fan, with the option to add a second for enhanced cooling performance. While other design variations exist, this model emphasizes simplicity and modern aesthetics.

Install Notes:

NH-D15

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.

Mugen 6

The Scythe Mugen 6 features a standard installation process, where brackets are first attached to the motherboard, followed by the cooler. It includes a single fan, with the option to install a second for enhanced cooling performance. Its design ensures compatibility with most motherboards, without interfering with RAM placement.

Cooling Performance:

NH-D15

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.

Mugen 6

This cooler delivers above-average performance and its performance is in line given its size and single fan configuration. With the option to add a second fan, it allows for improved cooling and a better noise-to-performance ratio at minimal cost, offering upgrade flexibility. However, in its default configuration, it may not be sufficient for high-end CPUs that generate significant heat.

Noise Performance:

NH-D15

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.

Mugen 6

This cooler boasts an excellent noise profile, thanks to its single 120mm fan. While adding a second fan can enhance overall cooling and improve the sound-to-performance ratio, it may also lead to increased noise levels at higher speeds. Overall, the cooler maintains a good balance between noise and performance, especially considering its size and fan configuration.

Summary:

NH-D15

The NH-D15 is a dual-tower cooler with two aluminum heatsinks and a pair of Noctua's 140mm NF-A15 PWM fans, ensuring superior heat dissipation for a wide range of processors, even those with high TDPs. Its six heat pipes efficiently transfer heat, making it suitable for high levels of overclocking and demanding situations. With its signature beige and brown color scheme, the NH-D15 is not only known for its performance but also its quiet operation, thanks to the fans' design and included Low-Noise Adaptors for further noise reduction during intense workloads or gaming sessions.

Mugen 6

The Scythe Mugen 6 features a straightforward installation process, with brackets attached to the motherboard before securing the cooler. Its monolithic design includes an exposed metal heatsink and polished top, hiding the heat-pipe ends for a clean, modern look. It comes with a single 120mm black fan, with the option to add a second for enhanced cooling performance. The cooler is compatible with most motherboards, avoiding interference with RAM placement. Offering above-average performance, the option for a second fan allows for improved cooling and a better noise-to-performance ratio, though overall noise levels may increase at higher speeds. In its default configuration, the cooler performs well but may not be sufficient for high-end CPUs that produce significant heat. Overall, it strikes an impressive balance between noise and performance.
