Noctua NH-L9x65 vs Thermalright AXP90 X36 Low Profile ITX CPU Cooler,

Overview of Low-Profile CPU Coolers

When it comes to low-profile CPU coolers, two prominent options are the Noctua NH-L9x65 and the Thermalright AXP90 X36. The Noctua NH-L9x65 is priced at $69.95, while the Thermalright AXP90 X36 is significantly more affordable at $20.39, making it about 71% cheaper. This price difference highlights the distinct market positioning of these coolers, appealing to different user needs and budgets.

Design and Dimensions

The Noctua NH-L9x65 boasts a compact height of 65mm, designed specifically for small form factor builds, while the Thermalright AXP90 X36 is even more compact at just 36mm tall. This makes the AXP90 X36 an excellent choice for ultra-tight spaces where height is a critical factor. However, the additional height of the NH-L9x65 may provide slightly better cooling performance due to its larger fan and heat sink area.

Cooling Performance

The NH-L9x65 features a highly optimized NF-A9x14 slim 92mm fan that supports PWM functionality for automatic speed control, providing low-noise operation. It is recommended for CPUs with low to moderate heat dissipation, which includes high-performance AMD Ryzen and Intel processors. On the other hand, the AXP90 X36 employs a 4×6mm AGHP heat pipe design, which allows it to maintain a noise level of just 22.4 DBA. While both coolers are designed for quiet operation, the NH-L9x65 may have a slight edge in thermal performance for those with moderate thermal output.

Compatibility

The Noctua NH-L9x65 is compatible with a wide range of Intel and AMD sockets, including Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4. This extensive compatibility makes it a versatile choice for various builds. Conversely, the AXP90 X36 supports Intel sockets 115X, 1200, and AMD AM4/AM5, making it equally adaptable but with a narrower range of supported Intel sockets. Users should consider their specific motherboard socket type when choosing between these two coolers.

Installation and Setup

Both coolers are designed for easy installation, but the Noctua NH-L9x65 includes the high-end NT-H1 thermal paste and the SecuFirm2 mounting system, which facilitates a straightforward setup on various CPU platforms. The Thermalright AXP90 X36, while also designed for ease of installation, does not specify the inclusion of thermal paste, which could be an additional cost to factor in. Therefore, if convenience is a priority, the NH-L9x65 may present a more complete package.

Noise Levels

The NH-L9x65 is designed for ultra-quiet operation, leveraging its PWM fan and Low-Noise Adaptor to minimize sound levels during operation. While specific noise levels for the NH-L9x65 are not provided, users often report a very quiet experience. The AXP90 X36, with its maximum noise level of 22.4 DBA, is also engineered for silent performance, making it suitable for noise-sensitive environments. However, the NH-L9x65's advanced design suggests it may operate even quieter under load.

Price and Value

The significant price difference between the two coolers cannot be overlooked. At $69.95, the NH-L9x65 is more than three times the price of the AXP90 X36, which retails for $20.39. This price point makes the AXP90 X36 an excellent entry-level option for budget-conscious users. However, the additional investment in the NH-L9x65 may be justified for those seeking superior performance and broader compatibility.

Which should you buy?

Choosing between the Noctua NH-L9x65 and the Thermalright AXP90 X36 ultimately depends on your specific needs and budget. If you're looking for a high-performance cooler that excels in quiet operation and compatibility, the NH-L9x65 is the superior choice, albeit at a higher price. Conversely, if you're working with a tighter budget and require a cooler that performs adequately in ultra-compact spaces, the AXP90 X36 offers exceptional value at about 71% less than its competitor. Consider your system requirements and thermal needs carefully before making your decision.
