Compare: NH-D15S vs Liquid Freezer II 240

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.

Liquid Freezer II 240

Highlighted by its captivating ARGB lighting, this cooler presents a streamlined look with a pair of 120-millimeter fans adorning its 240mm radiator. Cable management concerns are efficiently addressed from the start through the pre-daisy-chained ARGB and RPM cords. A seamless blend is achieved with its black radiator, fan frames, and water pipes, tailored to complement darker cooler setups. It's worth noting that the water pump, though possessing a distinctive design, may exhibit a more understated aesthetic when juxtaposed with AIO coolers showcasing more intricate pump designs.

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.

Liquid Freezer II 240

This cooler is relatively easy to install with the fans pre-installed on the radiator with the RPM connectors daisy chained neatly with a single connector coming out of the pump for the Fan inputs. However, this cooler requires it to be offset to the base mount, which can take some time to get right. Additionally, the heat pipes don't pivot from the pump which may make placement in certain setups difficult.

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.

Liquid Freezer II 240

Despite its compact size, this cooler delivers impressive cooling power through its pair of 120mm fans. It matches the cooling performance of leading air coolers, making it an excellent choice for setups that demand efficient cooling while avoiding the bulkiness of traditional air cooling solutions. However, if you're seeking even higher performance beyond what an air cooler can offer, transitioning to a 360mm setup becomes necessary.

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.

Liquid Freezer II 240

Operating with near-silent efficiency, the water pump ensures minimal noise disruption, while the pair of 120mm fans provide exceptional airflow at a manageable noise level. Consequently, the cooler excels in delivering impressive cooling performance with barely perceptible noise during typical usage scenarios. Nevertheless, when pushing a high TDP CPU to its limits, the cooler may produce some noise as it copes with the heightened heat load.

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.

Liquid Freezer II 240

Enhanced by ARGB lighting, this cooler boasts dual 120mm fans situated on a 240mm radiator, ensuring efficient cooling with discreet black components that complement darker setups. The installation process is made convenient through pre-installed fans and daisy-chained RPM connectors. Despite its compact size, it delivers efficient cooling comparable to premium air coolers; however, for heightened performance demands, a 360mm setup might be better suited. Operating with minimal noise, the water pump and fans collaborate to maintain exceptional airflow at manageable sound levels. During regular use, it offers efficient cooling with a slight noise presence, yet handling high TDP CPUs during intensive tasks may result in increased noise due to elevated heat loads.
