Compare: NH-D15S vs Mugen 6

Design and Aesthetics:

NH-D15S

The NH-D15S features a dual-tower design with a large aluminum heatsink and one 140mm NF-A15 PWM fan. The asymmetrical layout of the cooler allows for improved clearance for RAM and PCIe slots, making it more versatile for different motherboard layouts. Aesthetically, the NH-D15S 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-D15S

The NH-D15S comes with Noctua's SecuFirm2 mounting system, which provides compatibility with a wide range of Intel and AMD sockets. The installation process is straightforward, thanks to the clear instructions and high-quality components provided. Noctua also includes a tube of their premium NT-H1 thermal compound to ensure optimal thermal transfer between the CPU and heatsink.

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-D15S

The performance of the NH-D15S is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin array of the heatsink. 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. However, given this cooler only uses a single fan, this version of the NH-D15 doesn't perform as well as the NH-D15.

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-D15S

One of the standout features of the NH-D15S is its quiet operation. The included 140mm NF-A15 PWM fan is designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15S is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions.

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-D15S

The Noctua NH-D15S is a versatile, high-performance air cooler that offers excellent cooling capabilities and quiet operation. Its asymmetrical, dual-tower design makes it suitable for various system configurations, and its exceptional build quality ensures long-lasting performance. For users seeking a reliable and efficient cooling solution, the NH-D15S is a top choice.

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.
