Dimension comparison
Overview of Thermalright Assassin X 120 V2 Plus
The Thermalright Assassin X 120 V2 Plus CPU Cooler is priced at C$25.90 and showcases impressive features tailored for effective cooling. This cooler boasts a compact design with dimensions of 120(L)x96(W)x154(H)mm and utilises four 6mm heat pipes that apply Advanced Gravity Heat Pipe (AGHP) technology, ensuring optimal performance regardless of orientation. It comes with S-FDB bearings, which contribute to longevity and low noise levels while providing maximum cooling performance when required. Its compatibility with various Intel and AMD sockets makes it a versatile choice for different setups.
Overview of Thermalright Peerless Assassin 120 Black
The Thermalright Peerless Assassin 120 Black is a more premium option priced at C$54.90, offering advanced cooling capabilities. This cooler features a slightly larger size of 125(L)x135(W)x157(H)mm and incorporates six 6mm heat pipes, also utilising AGHP technology for effective heat dissipation. The design includes a dual-tower configuration and two PWM fans that can produce an airflow of 66.17 CFM at a maximum noise level of 25.6 dB(A). Its compatibility extends to a wide range of Intel and AMD sockets, making it an excellent choice for gamers and heavy users seeking superior cooling.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Peerless Assassin 120 Black has a clear advantage. With its dual-tower design and dual PWM fans, it can achieve a maximum airflow of 66.17 CFM, which is significantly higher than what a single fan setup can provide. The Thermalright Assassin X 120 V2 Plus, while efficient, does not match this airflow capability. The effective heat dissipation area of the Peerless Assassin is 9600 cm², which further emphasises its superior cooling performance. If you require a cooler that can handle extensive workloads, the Peerless Assassin is likely the better option.
Build Quality and Materials
Both coolers are constructed using high-quality materials, but they offer different design philosophies. The Assassin X 120 V2 Plus features pure aluminium cooling fins that maximise heat repulsion, while the Peerless Assassin 120 Black employs a full electroplating reflow welding process, enhancing its durability and aesthetics with a black paint finish. The choice of materials reflects the manufacturers' focus on performance and longevity. Notably, the Peerless Assassin’s double tower configuration may contribute to better thermal performance due to its larger surface area for heat dissipation.
Noise Levels
Noise is an important factor for many users when selecting a CPU cooler. The Thermalright Assassin X 120 V2 Plus utilises S-FDB bearings to maintain low noise levels, ensuring that the cooler operates quietly. While specific noise levels are not provided, the emphasis on noise reduction suggests a quieter operation during standard use. In comparison, the Peerless Assassin has a specified maximum noise level of 25.6 dB(A), which is relatively low but slightly higher than what one might expect from the Assassin X. For users prioritising silence, the Assassin X may offer a quieter experience, although both coolers are designed to operate efficiently without excessive noise.
Compatibility
When it comes to compatibility, both coolers support a wide range of CPU sockets. The Thermalright Assassin X 120 V2 Plus is compatible with Intel sockets including 1150, 1151, 1155, 1156, 1200, and 1700, as well as AMD’s AM4 and AM5. Similarly, the Peerless Assassin 120 Black supports the same Intel sockets and adds compatibility for LGA2066 and LGA2011. This makes the Peerless Assassin slightly more versatile for users with high-end Intel CPUs. Both products include necessary mounting plates and fasteners for easy installation, making them convenient choices for builders.
Price and Value
The Thermalright Assassin X 120 V2 Plus, priced at C$25.90, represents an excellent value for users seeking an affordable cooling solution without compromising performance. In contrast, the Thermalright Peerless Assassin 120 Black, at C$54.90, is a more substantial investment that reflects its advanced features and superior cooling capabilities. While the Assassin X is suitable for budget-conscious users or those with moderate cooling needs, the Peerless Assassin justifies its higher price with its enhanced performance and build quality, making it better suited for gamers and power users.
Which should you buy?
Choosing between the Thermalright Assassin X 120 V2 Plus and the Thermalright Peerless Assassin 120 Black ultimately depends on your specific needs and budget. If you are looking for an affordable, reliable cooler that performs well for standard use, the Assassin X is a solid choice. However, if you require superior cooling performance, especially for high-demand applications or overclocking, the Peerless Assassin is worth the extra investment. Its advanced features, dual fans, and enhanced airflow make it a more capable cooler overall.
