Overview of the Thermalright Phantom Spirit 120 SE Black
The Thermalright Phantom Spirit 120 SE Black is priced at C$46.71 and is designed for effective cooling. This air cooler features a unique blackened nano coating and a fully electroplated heat pipe, which enhances its heat dissipation capabilities. It employs AGHP technology with a 7x6mm heat pipe, ensuring a long service life of up to 20,000 hours thanks to its S-FDB bearings. With a height of 154mm, the cooler is compatible with a variety of cases and does not interfere with high-profile memory. Its aluminum fins and finely carved copper base allow for optimal heat dissipation, making it a solid option for users looking for reliable CPU cooling.
Overview of the Thermalright Peerless Assassin 120 SE Black
The Thermalright Peerless Assassin 120 SE Black is slightly more expensive at C$46.79 and offers robust cooling performance. This cooler also utilises a blackened nano coating and features a dual tower design, which significantly enhances its heat dissipation efficiency. At 155mm tall, it fits well in various chassis and accommodates high-profile memory without issues. The Peerless Assassin is equipped with two TL-C12C Reverse PWM fans, capable of reaching a fan speed of 1550 RPM. The dual fans generate an impressive air volume of 66.17 CFM, providing even stronger airflow compared to its counterpart, which is vital for keeping CPU temperatures low during heavy loads.
Cooling Performance Comparison
In terms of cooling performance, both coolers employ advanced technologies to enhance heat dissipation. The Phantom Spirit 120 SE Black uses a single tower design with an effective height of 154mm, while the Peerless Assassin has a dual tower configuration that stands at 155mm. Although the height difference is minimal, the dual fans of the Peerless Assassin allow it to achieve a higher air volume of 66.17 CFM, which can lead to better overall cooling performance under load. Both coolers use aluminum heat sinks with copper bases, but the additional airflow from the dual fans in the Peerless Assassin might provide it with a slight edge in cooling efficiency.
Installation and Compatibility
Both the Thermalright Phantom Spirit 120 SE Black and the Peerless Assassin 120 SE Black are designed for easy installation and compatibility with a wide range of CPU sockets. The Phantom Spirit supports Intel sockets including LGA1851, 1700, 1150, 1151, 1155, 1156, and 1200, along with AMD's AM4 and AM5. Similarly, the Peerless Assassin supports the same Intel and AMD socket types. Both products come with the necessary mounting plates and fasteners for easy setup. However, the Peerless Assassin’s dual fan setup may require slightly more space during installation, while the Phantom Spirit's single fan configuration simplifies this process.
Noise Levels
Noise levels are an essential consideration for many users when selecting a CPU cooler. The Peerless Assassin operates at a noise level of ≤25.6 dB (A), which is relatively quiet for a dual-fan setup providing higher airflow. On the other hand, while the Phantom Spirit does not specify its noise levels, the single-fan design typically results in quieter operation. Users seeking absolute silence may prefer the Phantom Spirit, while those prioritising performance may lean towards the Peerless Assassin for its superior cooling capabilities, even if it is a touch noisier.
Build Quality and Design
Both products boast high-quality build standards. The Phantom Spirit features a blackened nano coating, aluminum fins, and a finely carved copper base, ensuring durability and effective heat dissipation. The Peerless Assassin also employs a similar build quality, but with the added advantage of dual fans for enhanced airflow. The aesthetics of both coolers are sleek and modern, fitting well into most builds. However, the slightly larger design of the Peerless Assassin might appeal more to those who appreciate a bold cooling solution in their setup.
Price Comparison
The Thermalright Phantom Spirit 120 SE Black is priced at C$46.71, while the Thermalright Peerless Assassin 120 SE Black costs C$46.79. The price difference is minimal, making both coolers competitively priced in the market. Given that both products offer similar features and compatibility, the price can be a deciding factor. The Phantom Spirit may appeal to budget-conscious consumers, while the Peerless Assassin, with its dual fans and higher airflow, provides a compelling value proposition for those willing to spend a little more for enhanced cooling performance.
Which should you buy?
Choosing between the Thermalright Phantom Spirit 120 SE Black and the Thermalright Peerless Assassin 120 SE Black ultimately depends on your specific needs. If you prioritise a quieter operation and a simpler installation process, the Phantom Spirit may be the better choice for you. However, if you are looking for superior cooling performance, particularly under heavy loads, the Peerless Assassin's dual fans and higher airflow make it the more compelling option. Both coolers offer excellent build quality and compatibility, but the slight price difference may sway you based on your cooling requirements and preferences.
