Dimension comparison
Overview of the Noctua NH-D12L and Thermalright AXP90 X36
The Noctua NH-D12L is priced at $99.95, while the Thermalright AXP90 X36 is about 79% cheaper at $20.39. This significant price difference reflects the distinct market segments these coolers target. The Noctua aims for high performance and versatility, whereas the Thermalright offers a compact solution ideal for smaller builds.
Design and Build Quality
The Noctua NH-D12L features a low-height dual-tower design that stands at 145mm. This configuration allows for excellent cooling performance while ensuring compatibility with most 4U rackmount server cases. In contrast, the Thermalright AXP90 X36 boasts a notably compact stature at only 36mm tall, making it an attractive option for ITX setups. The AXP90 X36's all-metal platform and nickel plating enhance its corrosion resistance and durability, showcasing a solid build quality despite its smaller size.
Cooling Performance
The Noctua NH-D12L is designed for outstanding cooling efficiency, equipped with a state-of-the-art NF-A12x25r 120mm fan that operates whisper-quiet at idle. It achieves full cooling performance under load, making it an ideal choice for high-performance CPUs. On the other hand, the Thermalright AXP90 X36 utilizes a slim PWM fan, which operates at a noise level of 22.4 dBA. While it may not match the NH-D12L in sheer cooling power, it effectively manages heat for lower-end builds or in tight spaces.
Compatibility with Sockets
The NH-D12L provides impressive compatibility, supporting Intel LGA1700, LGA1200, and LGA115x sockets, along with AMD’s AM4 and AM5 sockets. This versatility allows it to fit a wide range of modern processors, making it a go-to choice for enthusiasts. Conversely, the Thermalright AXP90 X36 also supports a variety of sockets, including Intel LGA1150, LGA1151, LGA1200, and LGA1700, as well as AMD AM4 and AM5. However, its lower height may limit its compatibility with larger CPUs, particularly those requiring substantial cooling.
Installation Process
The NH-D12L comes with the SecuFirm2 mounting system, which simplifies installation across various platforms. This system is designed for user-friendliness, allowing even those with less experience to install the cooler effectively. In contrast, the AXP90 X36's installation process is straightforward due to its compact design and backplate fastener. Both coolers cater to ease of installation, but the NH-D12L offers additional features that enhance user experience.
Noise Levels
When it comes to noise levels, the Noctua NH-D12L excels, providing quiet operation thanks to its PWM-controlled fan. Users can expect minimal noise during operation, making it suitable for builds where silence is paramount. The Thermalright AXP90 X36, while also designed to be quiet, operates at a maximum of 22.4 dBA. This may be acceptable for most users, but it does not match the nearly silent performance of the NH-D12L, especially during high-load scenarios.
Warranty and Reliability
Noctua stands by its products with a generous six-year warranty, reflecting its confidence in the durability and performance of the NH-D12L. This warranty is a testament to the brand's commitment to quality. The Thermalright AXP90 X36 does not explicitly mention a warranty period in the provided data, which may raise concerns for users prioritizing long-term reliability. A solid warranty can significantly influence purchasing decisions, particularly for high-investment components.
Which should you buy?
The decision between the Noctua NH-D12L and the Thermalright AXP90 X36 largely depends on your specific needs. If you require high performance, extensive compatibility, and quiet operation, the Noctua NH-D12L is the superior choice, albeit at a higher price point of $99.95. However, if you're working with a compact build and need a budget-friendly option, the Thermalright AXP90 X36, priced at $20.39, offers decent performance in a low-profile form factor. Ultimately, both coolers serve their respective markets well, and your choice should align with your priorities—performance versus price and space constraints.
