Compare: NH-D15S vs AXP90-X47 Full Copper

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.

AXP90-X47 Full Copper

This cooler features a sleek, low-profile design, making it an excellent choice for compact builds where space is a priority. Its copper construction not only enhances thermal performance but also adds a distinctive look that stands out in any 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.

AXP90-X47 Full Copper

Installing this cooler is more involved than a standard cooler due to its low-profile design, which requires it to be screwed in from behind rather than from the top, as is common with most coolers. While the installation is relatively easy if the motherboard is not yet secured in the case, it can be challenging if you attempt to install it with the motherboard already mounted. Additionally, the cooler's brackets are attached via screws that need to be removed and swapped depending on the CPU you're using.

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.

AXP90-X47 Full Copper

Given its compact size, it’s no surprise that this cooler won’t top the charts in cooling performance. However, it delivers impressive efficiency for its form factor, outperforming stock coolers of similar size.

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.

AXP90-X47 Full Copper

With its high-speed 2700 RPM single fan, this cooler has the potential to produce higher noise levels than typical models. However, given its compact size, it's expected to become audible when delivering high-performance cooling.

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.

AXP90-X47 Full Copper

This cooler’s sleek, low-profile design makes it an excellent choice for compact builds where space is a priority. Its copper construction enhances thermal performance while adding a distinctive look to any setup. While it won’t compete with larger coolers in raw cooling power, it outperforms stock coolers of similar size. The high-speed 2700 RPM fan can produce noticeable noise under heavy loads, which is expected given its compact form factor. Installation is more involved than standard coolers, requiring mounting from behind rather than from the top, making it easier to install before securing the motherboard in the case. Additionally, its brackets must be swapped depending on the CPU, adding an extra step to the process.
