Thermalright Peerless Assassin 120 SE CPU Cooler vs Noctua NH-L9i-17xx

Brand Overview

Thermalright and Noctua are both reputable brands in the CPU cooling market, but they cater to different segments. Thermalright has over 20 years of experience and is known for offering high-performance cooling solutions. The Thermalright Peerless Assassin 120 SE CPU Cooler is a testament to this legacy, featuring a dual tower heatsink configuration and advanced ARGB fans. In contrast, Noctua is celebrated for its premium quality and has received more than 200 awards for its products. The Noctua NH-L9i-17xx is designed to meet the needs of users with compact systems, providing efficient cooling in a slim profile.

Design and Build Quality

The design and build quality of a CPU cooler can significantly affect its performance. The Thermalright Peerless Assassin 120 SE boasts dimensions of 125(L)x135(W)x155(H)mm, making it a robust option with a dual tower heatsink made of aluminum and copper. This configuration enhances heat dissipation while accommodating two high-performance ARGB fans. On the other hand, the Noctua NH-L9i-17xx stands out with its compact height of only 37mm, making it ideal for small form factor cases. Its tailored footprint ensures compatibility with all ITX, Micro-ATX, and ATX motherboards, which is a crucial consideration for those with limited space.

Cooling Performance

When it comes to cooling performance, both coolers excel in their respective design philosophies. The Thermalright Peerless Assassin 120 SE features six heat pipes with AGHP technology, which facilitates rapid heat exchange. The two ARGB fans can reach a maximum airflow of 66.17 CFM and operate at a noise level of 25.6 dB(A), which is relatively quiet for its performance level. In contrast, the Noctua NH-L9i-17xx is equipped with a renowned NF-A9x14 slim 92mm fan that is designed for low noise while maintaining effective cooling. This cooler is particularly suitable for moderate heat loads, providing full performance under load while remaining whisper-quiet at idle.

Compatibility

Compatibility is a crucial factor when choosing a CPU cooler, and both products cater to different user needs. The Thermalright Peerless Assassin 120 SE supports a wide range of Intel and AMD sockets, including LGA1150 through LGA1851 and AM4/AM5, making it a versatile choice for various builds. However, users need to ensure that their case and motherboard are compatible due to the cooler's dimensions. The Noctua NH-L9i-17xx, while limited to Intel sockets (LGA1700 and LGA1851), guarantees 100% RAM and PCIe compatibility on all supported motherboards, making it an excellent choice for compact builds where space is at a premium.

Installation Process

The installation process can vary significantly between different CPU coolers. The Thermalright Peerless Assassin 120 SE features an SS2 install system that requires careful consideration of motherboard compatibility, particularly when using AM4 and AM5 sockets, as it necessitates the use of the motherboard’s built-in backplate. In contrast, the Noctua NH-L9i-17xx includes the SecuFirm2 mounting system, which simplifies installation on compatible Intel CPUs. Furthermore, it comes with high-end NT-H1 thermal paste, enhancing the overall ease of setup for users.

Noise Levels

Noise levels are an essential consideration for users who prefer a quiet computing environment. The Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is commendable for a cooler of its size and performance. This makes it suitable for gaming or workstation setups where silence is appreciated. On the other hand, the Noctua NH-L9i-17xx is designed with noise reduction in mind, allowing for whisper-quiet operation at idle while still delivering sufficient cooling under load. Users looking for a balance between cooling performance and noise levels may find the Noctua cooler particularly appealing.

Price and Value

Price is a significant factor when deciding between the Thermalright Peerless Assassin 120 SE and the Noctua NH-L9i-17xx. The Peerless Assassin is priced at C$48.90, which is relatively affordable given its performance features. This cooler offers exceptional value for users seeking high performance without breaking the bank. In contrast, the Noctua NH-L9i-17xx comes at a higher price point of C$59.95. However, this cost reflects its premium build quality, compact design, and the brand's reputation for reliability. Users must weigh their budget against the specific needs of their system when considering these options.

Which should you buy?

In conclusion, choosing between the Thermalright Peerless Assassin 120 SE and the Noctua NH-L9i-17xx largely depends on your specific use case and system requirements. If you have a larger case and need a cooler that excels in high-performance scenarios, the Thermalright Peerless Assassin 120 SE offers excellent cooling capabilities and versatility at a lower price. However, if you are working with a compact build and require a cooler that guarantees compatibility with limited space, the Noctua NH-L9i-17xx is the superior choice, albeit at a higher cost. Ultimately, both coolers have their strengths, making them valuable options in the CPU cooling market.
