Thermalright Assassin X 120R SE V2 CPU Cooler, 4× vs Thermalright Phantom Spirit 120SE CPU Air Cooler,

Design and Build Quality

The Thermalright Assassin X 120R SE V2 boasts a compact design, measuring 120(L)x71(W)x148(H)mm, making it suitable for a variety of cases. Its use of aluminum for the heat sink and metal fasteners ensures durability. In contrast, the Thermalright Phantom Spirit 120SE has a slightly larger footprint at 125(L)x135(W)x154(H)mm, but it also utilizes high-quality materials, including anodized black frosted top and pure copper base technology. Both coolers reflect a commitment to quality, but the Phantom Spirit’s larger size might offer better cooling due to its increased material volume.

Cooling Performance

When it comes to cooling performance, the Thermalright Assassin X 120R SE V2 features four 6mm heat pipes and a fan speed of up to 1550 RPM, delivering an airflow of 66.17 CFM with a noise level of ≤25.6 dB(A). On the other hand, the Phantom Spirit 120SE employs seven heat pipes and dual 120mm fans, with a slightly lower maximum fan speed of 1500 RPM but similar airflow. The added heat pipes of the Phantom Spirit could theoretically provide improved heat dissipation, which might benefit high-performance CPUs, especially under load.

Noise Levels

Both coolers maintain a low noise profile, with the Thermalright Assassin X 120R SE V2 operating at a maximum of ≤25.6 dB(A), which is commendable for a CPU cooler. The Phantom Spirit 120SE matches this noise level, also reaching ≤25.6 dB(A). This similarity means that users can expect quiet operation from both models, making either choice suitable for users who prioritize a silent computing experience.

Compatibility

In terms of compatibility, the Thermalright Assassin X 120R SE V2 supports a wide range of Intel and AMD sockets, including Intel's LGA1150/1151/1155/1156/1200/1700/1851 and AMD's AM4/AM5. The Phantom Spirit 120SE offers similar compatibility with Intel's LGA1851/1700/1150/1151/1155/1156/1200 and AMD's AM4/AM5. Both coolers provide the necessary mounting plates or fasteners for installation, ensuring that either option can serve various builds effectively.

Price Point

The Thermalright Assassin X 120R SE V2 is priced at $16.59, making it significantly more affordable than the Thermalright Phantom Spirit 120SE, which retails for $35.90. This translates to a difference of about 117%, with the Phantom Spirit being more than double the price of the Assassin X. For budget-conscious consumers or those building a mid-range system, the Assassin X presents a compelling value proposition without sacrificing essential performance features.

Brand Reputation

Thermalright has a solid reputation in the cooling market, backed by over 20 years of experience in the industry. The brand is well-regarded for producing reliable and efficient cooling solutions. Both the Assassin X 120R SE V2 and the Phantom Spirit 120SE reflect this commitment to quality. However, the Phantom Spirit's more advanced technology, such as the AGHP 4.0, may appeal to enthusiasts looking for cutting-edge cooling solutions and longevity.

Installation and User Experience

Both the Thermalright Assassin X 120R SE V2 and the Phantom Spirit 120SE offer straightforward installation processes, with mounting hardware provided for various CPU sockets. The Assassin X features a height of 148mm, allowing for compatibility with a broad range of cases without obstructing memory installation. The Phantom Spirit, at 154mm, is similarly designed to avoid memory interference. Users can follow included instructions or tutorial videos for easy setup, ensuring a user-friendly experience with both products.

Which should you buy?

Choosing between the Thermalright Assassin X 120R SE V2 and the Phantom Spirit 120SE depends largely on your specific needs and budget. The Assassin X offers excellent cooling performance at an unbeatable price of $16.59, making it ideal for budget builds or users who prioritize cost efficiency. Conversely, if you are looking for advanced cooling technology and potentially better heat dissipation from the seven heat pipes, the Phantom Spirit at $35.90 could justify its higher price. Ultimately, both coolers are capable performers, but the choice hinges on whether you value cost savings or cutting-edge design features.
