Overview of the Thermalright Peerless Assassin 120 SE and TR-Phantom Spirit 120 SE

The Thermalright Peerless Assassin 120 SE is priced at £26.90, while the TR-Phantom Spirit 120 SE costs £29.09. Both are competitive air coolers designed for effective CPU cooling, but they have distinct features that may appeal to different users.

Thermalright has been in the market for over 20 years and is known for its focus on high-quality computer accessories. The Peerless Assassin boasts a strong double tower cooling design, while the TR-Phantom Spirit employs advanced AGHP technology for optimal performance. Understanding these nuances will help you make an informed decision.

Design and Build Quality

The Thermalright Peerless Assassin 120 SE features a robust design with dimensions of 125mm in length, 135mm in width, and 155mm in height. Its structure incorporates a metal fastener system catering to both Intel and AMD platforms, ensuring a secure installation. Weighing in at 0.97kg, it is relatively lightweight for its size.

In contrast, the TR-Phantom Spirit 120 SE also measures 125mm x 135mm, but stands slightly shorter at 154mm in height. It utilises anodised black frosted top and finely carved pure copper base technology, enhancing both aesthetics and functionality. The industrial-grade materials used in its construction suggest a durability designed to withstand extensive use.

Cooling Performance

In terms of cooling performance, both coolers utilise double PWM fans, although they differ slightly in specifications. The Thermalright Peerless Assassin features fans capable of reaching up to 1550 RPM, with a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A). This configuration aims to provide a balance between cooling efficiency and noise management.

On the other hand, the TR-Phantom Spirit's fans operate at a slightly lower maximum speed of 1500 RPM, yet they achieve the same airflow of 66.17 CFM and maintain the same noise level of 25.6 dB(A). Despite the marginal RPM difference, both coolers are designed to deliver effective cooling performance while keeping noise to a minimum.

Innovative Technologies

The Thermalright Peerless Assassin employs the AGHP technique, which utilises six 6mm heat pipes to enhance heat transfer efficiency. This design effectively addresses the inverse gravity effect, making it adaptable for both vertical and horizontal orientations. The use of pure copper and electroplated reflow welding further contributes to its cooling capabilities.

Conversely, the TR-Phantom Spirit incorporates a more advanced AGHP upgraded 4th generation technology with seven 6mm heat pipes. This enhancement allows it to handle a Thermal Design Power (TDP) range from 105W to 280W, which may be particularly beneficial for users with high-performance CPUs. The S-FDB bearings used in the fans promote a longer service life, promising up to 20,000 hours of operation.

Compatibility

Both the Thermalright Peerless Assassin and the TR-Phantom Spirit are compatible with a wide range of CPU sockets. The Peerless Assassin supports Intel sockets LGA1150 through LGA1851 and AMD AM4 and AM5. This broad compatibility ensures that it can fit into most modern builds without issues.

The TR-Phantom Spirit also supports similar Intel and AMD sockets, including LGA1700, LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, AM4, and AM5. This versatility in compatibility for both coolers allows users greater flexibility when upgrading or building systems.

Noise Levels

Noise levels are crucial for many PC builders, especially for those who prefer a quieter computing experience. Both the Thermalright Peerless Assassin and the TR-Phantom Spirit operate at a maximum noise level of 25.6 dB(A). This level is considered relatively quiet, ensuring that neither cooler becomes a significant source of noise during operation.

The similar noise ratings suggest that both products are designed with noise reduction in mind, allowing users to enjoy their systems without the distraction of excessive fan noise.

Price Comparison

The Thermalright Peerless Assassin is more budget-friendly at £26.90, making it an attractive option for those looking to save without sacrificing quality. In contrast, the TR-Phantom Spirit is priced at £29.09, reflecting its advanced features and technology.

While the price difference of £2.19 may seem minimal, it could influence budget-conscious buyers. Those willing to invest a bit more may find additional value in the enhanced technology and durability offered by the TR-Phantom Spirit.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE and the TR-Phantom Spirit 120 SE ultimately depends on your specific needs and budget. The Thermalright Peerless Assassin is a solid choice for users looking for a reliable, cost-effective air cooler with good performance. It offers essential features and compatibility for most builds.

On the other hand, if you are seeking the latest technology with superior heat handling and durability, the TR-Phantom Spirit could be the preferable option. Its enhanced AGHP technology and slightly more robust build may justify the higher price for enthusiasts and high-performance users. Consider your requirements and budget to make the best choice for your setup.
