Compare: NH-D15S vs Liquid Freezer III 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 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-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 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-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 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-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 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-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 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.
