Compare: Liquid Freezer II 240 vs NH-D15 G2

Design and Aesthetics:

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.

NH-D15 G2

This cooler is quite large and showcases Noctua's signature design, appealing to diehard PC builders who don't want to compromise on cooling performance. The NH-D15 G2 closely resembles the previous generation, with a few updates. This version features eight heat pipes and offset depths on the two heatsinks

Install Notes:

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.

NH-D15 G2

The NH-D15 G2 retains the same installation design as its predecessor, with the addition of a new bracket that allows for offset mounting on AM5 CPUs. The installation process is straightforward, guided by clear instructions that adhere to industry standards for top-tier coolers. However, the cooler's large size may pose challenges when maneuvering it within the case.

Cooling Performance:

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.

NH-D15 G2

The Noctua's NH-D15 G2 cooler is hard to beat in terms of cooling performance, even outperforming AIOs from various other brands—a result expected given its larger size. However, when compared to the previous generation, its performance is on par, offering little improvement.

Noise Performance:

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.

NH-D15 G2

Compared to the average cooler, the Noctua NH-D15 G2 is louder than most on the market. However, when performance is evaluated on a noise-normalized basis, this cooler is tough to beat, offering excellent cooling for a given noise level. This means you can keep your cooler quiet when needed, while still having the headroom to increase the speed for enhanced cooling performance.

Summary:

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.

NH-D15 G2

The Noctua NH-D15 G2 retains the familiar installation design of its predecessor, with the addition of a new bracket for offset mounting on AM5 CPUs. While its large size may make installation a bit challenging, the process is straightforward, with clear instructions that meet industry standards. The cooler's substantial size is matched by its performance, offering exceptional cooling that even surpasses many AIOs from other brands. Although its performance is on par with the previous generation, the NH-D15 G2 still delivers excellent cooling, particularly when considering noise levels. Despite being louder than the average cooler, it excels in noise-normalized performance, allowing users to maintain quiet operation while having the flexibility to ramp up speed for maximum cooling when needed.
