Noctua NH-L9i-17xx vs Thermalright AXP90 X36 Low Profile ITX CPU Cooler,

Overview of CPU Coolers

When it comes to low-profile CPU coolers, the Noctua NH-L9i-17xx and the Thermalright AXP90 X36 stand out as notable contenders. The Noctua is priced at $49.95, while the Thermalright comes in at $20.39, making it about 59% cheaper than its competitor. Both coolers are designed for compact builds, but they cater to different needs and budgets.

Design and Build Quality

In terms of design, the Noctua NH-L9i-17xx features a height of 37mm, which allows it to fit seamlessly into small form factor cases. It is built with a proven premium heatsink noted for receiving over 200 awards, showcasing its quality and effectiveness. On the other hand, the Thermalright AXP90 X36 has a slightly shorter height of 36mm and is made with an all-metal platform, ensuring durability. While both coolers are designed for compact setups, the Noctua's extensive recognition for quality places it a notch above in terms of build prestige.

Cooling Performance

The Noctua NH-L9i-17xx is equipped with the renowned NF-A9x14 slim 92mm fan, which operates quietly while delivering full cooling performance under load. This cooler is particularly suitable for moderate heat loads, making it a solid choice for Intel Core processors. In contrast, the Thermalright AXP90 X36 features 4×6mm AGHP heat pipes and achieves a noise level of 22.4 DBA. While the Thermalright is effective, the Noctua's established reputation for cooling efficiency may make it the preferred option for those prioritizing performance.

Compatibility

Compatibility is a vital consideration when selecting a CPU cooler, and both models excel in this regard. The Noctua NH-L9i-17xx is tailored for Intel LGA1700 and LGA1851 platforms, ensuring 100% RAM and PCIe compatibility across various motherboard sizes. The Thermalright AXP90 X36 offers broader compatibility, supporting Intel LGA1150/1151/1200/1700/1851 as well as AMD AM4 and AM5 sockets. This versatility makes the Thermalright a great choice for users with mixed-platform setups, while the Noctua is specifically optimized for Intel users.

Noise Levels

The Noctua NH-L9i-17xx is designed for whisper-quiet operation, particularly at idle, thanks to its advanced fan technology. This cooler is a great option for those sensitive to noise, making it ideal for home theater PCs or quiet office builds. Conversely, the Thermalright AXP90 X36 operates at a maximum noise level of 22.4 DBA, which is relatively quiet but does not match the Noctua's performance in this aspect. If silence is a top priority, the Noctua may be the better choice.

Installation Process

Installation is often a deciding factor for users, and here the Noctua NH-L9i-17xx shines with its included SecuFirm2 mounting system. This design simplifies the installation process on Intel CPUs, making it user-friendly for even novice builders. The Thermalright AXP90 X36 also includes a back plate fastener, but it may not be as straightforward as Noctua's solution. For users seeking ease of installation, the Noctua offers a more streamlined experience.

Price Comparison

The price difference between the two coolers is significant, with the Noctua NH-L9i-17xx retailing for $49.95 and the Thermalright AXP90 X36 priced at $20.39. This amounts to a savings of about $29.56 if you opt for the Thermalright. While the Noctua may justify its higher price with performance and brand reputation, the Thermalright's lower cost makes it an appealing option for budget-conscious consumers.

Which should you buy?

Ultimately, the choice between the Noctua NH-L9i-17xx and the Thermalright AXP90 X36 comes down to your specific needs and preferences. If you seek superior build quality, quieter operation, and proven cooling performance, the Noctua is worth the investment. However, if price is your primary concern and you require compatibility with multiple platforms, the Thermalright presents a compelling option. Consider your priorities—be it performance, noise, compatibility, or budget—to make the best decision for your build.
