Dimension comparison
Overview of the Thermalright Peerless Assassin 120 SE V2
The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is priced at $38.99. It features a dual tower design with six heat pipes and dual 120mm PWM fans that reach speeds of up to 1850 RPM. This cooler is designed for both AMD AM4/AM5 and Intel LGA1851/1700 platforms, making it a versatile option for various builds. Its dual tower structure enhances heat dissipation, which is ideal for high-load tasks such as gaming and multitasking.
Overview of the Thermalright PS120SE ARGB
The Thermalright PS120SE ARGB CPU Air Cooler is slightly cheaper at $34.94, making it about 17% less expensive than its counterpart. This model boasts seven heat pipes and dual 120mm PWM fans, with a maximum fan speed of 1500 RPM. It supports a wider range of Intel sockets, including LGA1700, and features advanced AGHP technology for improved cooling efficiency. The ARGB lighting adds a visually appealing element to any PC setup.
Cooling Performance
In terms of cooling performance, the Peerless Assassin 120 SE V2 has a slight edge due to its dual tower design and higher fan speed, which can reach up to 1850 RPM. This allows for better airflow, rated at 88.89 CFM, which is beneficial during intense gaming or heavy computational tasks. In contrast, the PS120SE is rated at 66.17 CFM with a lower maximum RPM of 1500. While the PS120SE employs seven heat pipes to enhance heat transfer, the overall cooling performance may not match the efficiency of the Peerless Assassin under high loads.
Installation and Compatibility
Both coolers offer broad compatibility with various CPU sockets, including AMD AM4/AM5 and Intel LGA1700/1150/1151/1200. The Peerless Assassin is advantageous for users focused on AMD builds, while the PS120SE provides support for a slightly broader range of Intel sockets. Installation for both coolers appears straightforward, as they come with the necessary mounting hardware and instructions. However, the height of the PS120SE is marginally shorter at 154mm compared to the Peerless Assassin's 155mm, giving it a slight edge in cases with limited space.
Noise Levels
When it comes to noise levels, the Peerless Assassin 120 SE V2 operates at a noise level of 29.5 dBA, which is relatively quiet but may be more noticeable under heavy loads due to its higher RPM. On the other hand, the PS120SE is quieter, with a maximum noise level of just 25.6 dBA. This lower noise output could be a deciding factor for users who prioritize a quiet computing environment, especially during long gaming sessions or intensive tasks.
Build Quality and Design
Both coolers are constructed with high-quality materials, but they cater to different aesthetic preferences. The Peerless Assassin features a traditional design with an emphasis on cooling performance. In contrast, the PS120SE incorporates ARGB lighting, which allows for customization and synchronization with other RGB components in a build. The PS120SE's use of industrial-grade PBT + PC material and S-FDB bearings suggests a focus on durability and longevity, promising an industrial service life of up to 20,000 hours.
Price Comparison
The Peerless Assassin 120 SE V2 is priced at $38.99, while the PS120SE is available for $34.94. This makes the PS120SE approximately $4.05 cheaper, or about 17% less expensive overall. While both coolers provide excellent value for their performance, the price difference could influence budget-conscious consumers. However, the extra features of the PS120SE, including its ARGB lighting and broader compatibility with Intel sockets, may justify its cost for some users.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Thermalright PS120SE ARGB ultimately depends on your specific needs. If you require superior cooling performance and don't mind a slightly higher price, the Peerless Assassin is the better option. However, if you prefer a quieter operation, aesthetic appeal with ARGB lighting, and a slightly lower price, the PS120SE is an excellent choice. Each cooler has its strengths, so consider what features matter most for your build before making a decision.
