Compare: NH-D15 G2 vs Liquid Freezer III 240

Design and Aesthetics:

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

Liquid Freezer III 240

This cooler showcases a sleek, symmetrical design with a modern aesthetic. While this model doesn’t include RGB lighting, there are versions available that do, allowing you to choose based on your style preferences. Overall, it adds a clean, contemporary look to your PC setup.

Install Notes:

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.

Liquid Freezer III 240

The Arctic Freezer III 240 retains the easy installation features of its predecessor while offering added convenience. What sets this cooler apart is its pre-installed fans on the radiator, simplifying the setup compared to other all-in-one (AIO) coolers. The detachable CPU mounting bracket further enhances the installation process by eliminating interference from aesthetic components. However, attaching the control cable to the motherboard can be challenging once the cooler is mounted. To avoid this, it’s advisable to connect the cable to the motherboard before installing the cooler.

Cooling Performance:

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.

Liquid Freezer III 240

The Arctic Freezer III 240 offers some performance improvements over its predecessor, the Arctic Freezer 240, but this comes with increased noise. Relative to other coolers in it's weight class, this cooler outperforms most.

Noise Performance:

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.

Liquid Freezer III 240

The Arctic Freezer III 240 has a more powerful pump that has the potential to be quite audible. Since our testing was conducted with the AIO pump running at 100% speed, lowering the pump speed during less demanding tasks can help reduce noise levels without sacrificing too much performance.

Summary:

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.

Liquid Freezer III 240

The Arctic Freezer III retains its user-friendly installation design, featuring pre-attached radiator fans and a detachable CPU mounting bracket for simpler setup. However, connecting the control cable can be challenging once the cooler is installed, so it's best to attach it beforehand. The cooler sports a modern design, with some versions offering RGB lighting for added customization. While it boasts aesthetic improvements and lower noise levels compared to standard coolers and its predecessor, the Arctic Freezer 240, the Arctic Freezer III 240 delivers average performance and struggles to effectively cool high-core CPUs under heavy workloads.
