Overview of the Noctua NH-L12S and Thermalright AXP90 X36

The Noctua NH-L12S is a premium low-profile CPU cooler priced at $74.95, while the Thermalright AXP90 X36 is a more budget-friendly option at $20.39, making it about 73% cheaper than the Noctua cooler. Both are designed for compact builds, but they cater to different market segments. The NH-L12S targets users seeking high-end performance and quiet operation, whereas the AXP90 X36 focuses on affordability and decent cooling capabilities for entry-level builds.

Design and Build Quality

The Noctua NH-L12S boasts a total height of 70mm, featuring a high-quality, sleek design that is characteristic of Noctua's premium products. Its construction includes a highly optimized NF-A12x15 120mm fan, known for its durability and low-noise operation. In contrast, the Thermalright AXP90 X36 is significantly shorter at 36mm, allowing it to fit into even tighter ITX cases. While the AXP90 X36 is made with all-metal components and nickel plating for corrosion resistance, it may not match the premium feel of Noctua's materials. The NH-L12S is recognized for its overall quality, reinforced by a 6-year warranty.

Performance

In terms of cooling performance, the Noctua NH-L12S is engineered for efficiency and quietness, thanks to its advanced fan technology and PWM support. The NH-L12S is designed as a successor to the award-winning NH-L12, making it an appealing choice for high-performance CPUs like the Intel Core Ultra and AMD Ryzen series. The AXP90 X36, while more affordable, features a 4×6mm AGHP heatpipe design and operates at a noise level of 22.4 DBA, which is acceptable but not as quiet or efficient as the NH-L12S. Users requiring top-tier cooling for high-demand applications should consider the NH-L12S over the AXP90 X36.

Installation Process

When it comes to installation, the Noctua NH-L12S includes the SecuFirm2 mounting system, designed for easy and secure installation on various Intel and AMD sockets, including LGA1851 and AM5. This user-friendly installation system is a significant advantage for those who may not be as experienced with CPU cooler setups. The Thermalright AXP90 X36 also offers a straightforward installation process, utilizing a backplate fastener for secure mounting on Intel and AMD platforms. However, the NH-L12S's comprehensive compatibility may give it an edge for users with a wider array of CPU sockets.

Noise Levels

Noise levels are a critical factor for many users. The Noctua NH-L12S is designed to operate quietly, especially with its Low-Noise Adaptor, ensuring a near-silent experience during operation. This makes it an excellent choice for users building a quiet workstation or home theater PC. The Thermalright AXP90 X36, while also designed to be relatively quiet, operates at a maximum noise level of 22.4 DBA, which may not be ideal for users sensitive to noise. For those prioritizing silence, the NH-L12S is likely the better choice.

Compatibility

Both coolers are compatible with a range of platforms, but the Noctua NH-L12S supports a broader array of Intel and AMD sockets, including the latest LGA1700 and AM5 platforms. The Thermalright AXP90 X36 supports the widely used LGA1150/1151/1200 and AM4/AM5 sockets, which covers many mainstream users. However, if you're looking to future-proof your build with the latest technology, the NH-L12S's broader compatibility makes it a more versatile option.

Price Comparison

The price difference between these two coolers is substantial. The Noctua NH-L12S is priced at $74.95, while the Thermalright AXP90 X36 comes in at just $20.39. This means that the NH-L12S is approximately 268% more expensive than the AXP90 X36. While the higher price point reflects the premium quality and performance of the NH-L12S, budget-conscious users may find the AXP90 X36 to be more in line with their needs, especially for less demanding setups.

Which should you buy?

Ultimately, your choice between the Noctua NH-L12S and the Thermalright AXP90 X36 will depend on your specific needs and budget. If you require a high-performance, quiet, and reliable CPU cooler and are willing to invest, the Noctua NH-L12S is the clear winner. However, if you're looking for a cost-effective solution that still provides decent cooling for basic tasks or light gaming, the Thermalright AXP90 X36 is a compelling option. Each cooler has its strengths, but for serious users, the NH-L12S's features and build quality make it the superior choice.
