Noctua NH-D12L vs Thermalright AXP90 X47 Full Low Profile CPU Cooler

Overview of the Noctua NH-D12L and Thermalright AXP90 X47

The Noctua NH-D12L is priced at C$131.95, while the Thermalright AXP90 X47 is significantly more budget-friendly at C$43.39. This price difference reflects the distinct target audiences and cooling capabilities of each cooler. The NH-D12L is designed for enthusiasts requiring robust cooling performance and compatibility with larger cases, whereas the AXP90 X47 caters to users with space constraints, such as those using HTPC or ITX builds.

Design and Build Quality

The Noctua NH-D12L features a low-height dual-tower heatsink design at 145mm tall, which combines excellent cooling performance with compatibility for most 4U rackmount server cases. Its asymmetrical layout allows for 100% RAM compatibility across various socket types. In contrast, the Thermalright AXP90 X47 is a compact 47mm in height, making it ideal for smaller builds. Its design incorporates advanced AGHP technology, enhancing cooling efficiency. While the NH-D12L is built for performance and versatility, the AXP90 X47 prioritizes low-profile installation.

Cooling Performance

The Noctua NH-D12L is built with a state-of-the-art NF-A12x25r 120mm fan that provides automatic speed control via PWM, ensuring optimal cooling performance without excessive noise. This cooler is particularly suited for high-performance CPUs, making it a preferred choice for gaming and workstation builds. On the other hand, the Thermalright AXP90 X47 utilises a 92mm PWM fan that can reach speeds of up to 2700 RPM, offering a maximum air volume of 42.58 CFM. While the AXP90 X47 is designed to be quiet with noise levels of 22.4 dB(A), its lower CFM may not match the cooling effectiveness of the NH-D12L under heavy loads.

Compatibility

The NH-D12L supports a wide range of CPU sockets, including Intel LGA1700, LGA1200, and AMD AM4/AM5, ensuring it can fit various systems with ease. Its installation is further simplified by the included SecuFirm2 mounting system and high-end NT-H1 thermal paste. The Thermalright AXP90 X47 also boasts broad compatibility, supporting Intel sockets such as LGA1700 and AMD AM4/AM5, making it versatile for different platforms. However, its low-profile design may limit performance in more demanding setups compared to the NH-D12L.

Noise Levels

The Noctua NH-D12L prides itself on quiet operation, especially at idle, thanks to its intelligent fan controls. While specific dB levels for the NH-D12L are not provided, Noctua is renowned for its low-noise cooling solutions. In comparison, the Thermalright AXP90 X47 operates at a maximum noise level of 22.4 dB(A), which is relatively quiet but may still be noticeable in a silent build. Users prioritising ultra-quiet performance might lean towards the NH-D12L, as it promises whisper-quiet operation under typical workloads.

Installation Process

The installation process for both coolers is designed to be user-friendly. The Noctua NH-D12L includes a comprehensive installation guide and the SecuFirm2 mounting system that simplifies the setup on various sockets. The high-quality thermal paste further enhances the installation experience. The Thermalright AXP90 X47 also provides a straightforward installation process, complete with corresponding metal mounting fasteners for different platforms. While both coolers are manageable for users with basic technical skills, the NH-D12L’s additional features may provide a smoother experience.

Price-to-Performance Ratio

With a price of C$131.95, the Noctua NH-D12L is positioned as a premium option that offers high-end performance and build quality. This cooler is ideal for users who require superior cooling and are willing to invest in long-term reliability, supported by a 6-year manufacturer’s warranty. Conversely, the Thermalright AXP90 X47, priced at C$43.39, presents an excellent value for budget-conscious consumers. While it may not match the NH-D12L in raw performance, its low-profile design and respectable cooling capabilities make it a practical choice for smaller builds.

Which should you buy?

Choosing between the Noctua NH-D12L and the Thermalright AXP90 X47 largely depends on your specific needs. If you are looking for high-performance cooling for a standard-sized or larger case, and quiet operation is a priority, the NH-D12L is the superior choice despite its higher price. However, if you are constrained by space and need a budget-friendly solution for an HTPC or small form factor build, the AXP90 X47 is a commendable option that delivers solid performance without breaking the bank. Ultimately, your choice should align with your cooling requirements, case size, and budget.
