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.

Assassin X 120 R SE

Despite its budget-friendly nature, this cooler impresses with a surprisingly refined and visually appealing design that seamlessly blends aesthetics into any PC setup. It serves as an excellent and stylish choice for maintaining optimal CPU temperatures, transcending budget constraints.

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.

Assassin X 120 R SE

This cooler employs a conventional installation process commonly found in mainstream air coolers, utilizing a pair of brackets for connection, first to the motherboard and then to the cooler. Thanks to its compact size, it easily slots into place with minimal fuss.

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.

Assassin X 120 R SE

With its combination of four heat pipes and a solitary fan, this cooler effectively provides robust cooling capabilities. Although it may not match the extreme heat dissipation of dual heatsink coolers, it remains a top-notch option for those seeking efficient cooling solutions within the realms of low to moderate thermal demands.

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.

Assassin X 120 R SE

Fitted with a four heat pipes and a single fan, this cooler brings forth considerable cooling for its size. Although it may not compete with dual heatsink coolers regarding handling extreme cooling needs, it remains a standout selection for those whose cooling needs fall within the spectrum of low to moderate demands.

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.

Assassin X 120 R SE

The Thermalright Assassin X 120 R SE offers an easy installation process with brackets securing it to the CPU backplate. This cooler has a visually appealing design despite its budget-friendly nature. Equipped with four heat pipes and a single fan, it provides strong cooling performance, making it a solid choice for those with moderate cooling needs.
