Thermalright Peerless Assassin 120 SE CPU Cooler vs Noctua NM-i17xx-MP78

Overview of the Products

When considering CPU cooling solutions, the Thermalright Peerless Assassin 120 SE and the Noctua NM-i17xx-MP78 offer distinct advantages tailored for different user needs. The Peerless Assassin 120 SE is a full CPU cooler priced at C$48.90, while the NM-i17xx-MP78 serves as a mounting upgrade kit for Noctua coolers, available for C$12.95. This fundamental difference in product type sets the stage for how each can be utilized in a computer cooling setup.

Design and Build Quality

The Thermalright Peerless Assassin 120 SE features a robust design with dimensions of 125mm x 135mm x 155mm, employing a dual tower configuration that enhances heat dissipation. It incorporates a combination of aluminum and copper materials, promising durability and efficient cooling performance. In contrast, the Noctua NM-i17xx-MP78 is a specialized mounting kit crafted for compatibility with Intel’s LGA1851 and LGA1700 sockets. While it may not have the same physical presence as the Peerless Assassin, its dedicated one-piece backplate ensures reliable contact pressure when installing compatible coolers.

Cooling Performance

The Thermalright Peerless Assassin 120 SE is equipped with two high-performance ARGB fans, each capable of running at 1550 RPM and delivering a maximum airflow of 66.17 CFM. This configuration is designed to maintain optimal temperatures even under heavy loads. On the other hand, the Noctua NM-i17xx-MP78 does not include any cooling components, as it merely facilitates the installation of existing coolers. Therefore, if cooling performance is your primary concern, the Peerless Assassin is the clear winner with its integrated fan system.

Compatibility and Installation

Compatibility is a crucial factor when choosing cooling solutions. The Thermalright Peerless Assassin 120 SE supports a wide range of Intel and AMD sockets, including LGA1150, LGA1151, LGA1200, and AM4/AM5. However, it requires the original motherboard's backplate for installation on AM4 and AM5 systems, which may complicate setup for some users. In contrast, the Noctua NM-i17xx-MP78 is specifically designed for LGA1851 and LGA1700 sockets, making it an excellent choice for users looking to upgrade their existing Noctua coolers. Its straightforward installation process with fixed struts can also appeal to those less experienced with hardware.

Noise Levels

The Thermalright Peerless Assassin 120 SE operates at a rated noise level of 25.6 dB(A), indicating a relatively quiet performance under load. This aspect is particularly important for gamers or professionals who prioritize a silent computing environment. The NM-i17xx-MP78, being a mounting kit, does not produce noise on its own, but the overall noise level would depend on the cooler it is paired with. Therefore, if noise levels are a critical consideration, the Peerless Assassin provides a quantifiable advantage.

Brand Reputation and Experience

Thermalright boasts over 20 years of experience in the cooling industry, establishing a strong reputation for high-performance products. The Peerless Assassin 120 SE reflects this heritage with its well-engineered design. Noctua, on the other hand, is also renowned for its quality and reliability in cooling solutions, particularly known for silent operation. While both brands have their merits, Thermalright's extensive experience may offer an extra layer of confidence to users selecting the Peerless Assassin.

Price and Value

The Thermalright Peerless Assassin 120 SE is priced at C$48.90, reflecting its comprehensive cooling capabilities and dual-fan design. In comparison, the Noctua NM-i17xx-MP78 retails at a significantly lower price of C$12.95, which is appealing for users who already own compatible Noctua coolers and simply need a mounting upgrade. While the NM-i17xx-MP78 offers excellent value for its specific purpose, the Peerless Assassin provides a complete cooling solution, justifying its higher price tag.

Which should you buy?

If you are in need of a full CPU cooling solution with high performance and versatility, the Thermalright Peerless Assassin 120 SE is the better option. Its dual tower design, effective cooling capabilities, and broad compatibility make it a standout choice for various builds. Conversely, if you already possess a compatible Noctua cooler and are looking to enhance its installation on newer Intel sockets, the NM-i17xx-MP78 is a cost-effective solution. Ultimately, your choice will depend on whether you need a complete cooler or an upgrade for an existing unit.
