Overview of Thermalright Peerless Assassin 120 SE ARGB
The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler is designed to provide efficient cooling with an emphasis on aesthetics. Currently priced at C$46.90, it features a dual tower design that enhances cooling performance. The cooler measures 125mm in length, 135mm in width, and 155mm in height, making it relatively compact for a dual tower cooler. Equipped with two PWM fans that operate at a maximum speed of 1500 RPM, it delivers an airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). This model is compatible with a wide array of CPU sockets, including Intel’s LGA 1700 and AMD’s AM4, ensuring versatility for various setups.
Overview of Thermalright Phantom Spirit 120 SE Black
The Thermalright Phantom Spirit 120 SE Black CPU Air Cooler is another competent option, priced slightly lower at C$46.71. This cooler also employs a dual tower setup, with dimensions of 125mm by 135mm by 154mm. It is specifically designed to optimise heat dissipation through its blackened nano coating and finely carved copper base. The Phantom Spirit features a unique memory cut corner avoidance design, which enhances compatibility with tall RAM modules. Its heat pipes, upgraded to 7x6mm with AGHP technology, promise longevity and effective cooling performance, making this cooler a strong contender for both gamers and PC builders.
Cooling Performance Comparison
The cooling performance of both air coolers is noteworthy, but they employ slightly different technologies. The Peerless Assassin utilises six 6mm heat pipes and is rated for a thermal design power (TDP) of 120 to 245W. This indicates a robust capacity for dissipating heat, making it suitable for high-performance CPUs. In contrast, the Phantom Spirit offers a slightly lower TDP rating due to its 7x6mm heat pipe configuration, aimed at effective heat dissipation while maintaining a compact design. Both coolers tout advanced AGHP technology, which addresses the inverse gravity effect, but the Peerless Assassin might edge out in extreme cooling scenarios due to its higher TDP rating.
Noise Levels
In terms of operational noise, the Peerless Assassin maintains a noise level of 25.6 dB(A), which is relatively quiet for a cooler of its capacity. This is particularly beneficial for users who prefer a silent setup. The Phantom Spirit's specifications do not explicitly mention its noise levels, but it is designed with S-FDB bearings that are known for quiet operation and longevity. Users can expect the Phantom Spirit to perform quietly, but without specific dB measurements, it’s hard to definitively compare the sound profiles of both coolers.
Compatibility with CPU Sockets
When it comes to compatibility, both coolers support a variety of Intel and AMD CPU sockets. The Peerless Assassin is compatible with Intel’s LGA 115X, 1200, 1700, and AMD’s AM4 sockets. On the other hand, the Phantom Spirit supports an even broader range of Intel sockets, including LGA 1851, 1700, and AM4/AM5 for AMD. This might make the Phantom Spirit a better option for users who are looking to future-proof their builds or have specific motherboard configurations in mind.
Build Quality and Design
The build quality of both products is commendable, reflecting Thermalright's commitment to durable cooling solutions. The Peerless Assassin features an aluminum heat sink and is designed to leave room for RAM installation, which is a thoughtful detail for high-end builds. Meanwhile, the Phantom Spirit's blackened finish and anodized top pieces give it a sleek appearance, appealing to aesthetics-focused users. Its copper base technology enhances thermal conductivity, making it not only visually appealing but also effective in cooling performance.
Aesthetic Appeal
The aesthetic aspect of the Peerless Assassin shines with its ARGB lighting effects, making it an attractive choice for gamers who wish to showcase their builds. The dual fans provide a colourful glow that can be customized to match other components. Conversely, the Phantom Spirit opts for a more understated black design, which may appeal to users who prefer a more minimalist look. While both coolers have their unique visual strengths, the choice largely depends on personal preference regarding RGB lighting versus a sleek, professional appearance.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE ARGB and the Thermalright Phantom Spirit 120 SE Black ultimately hinges on your specific needs and preferences. The Peerless Assassin stands out for its higher TDP capacity, effective dual fan setup, and vibrant ARGB lighting, making it a great choice for users seeking high performance and aesthetics. Conversely, the Phantom Spirit offers excellent compatibility, a sleek design, and potentially quieter operation at a slightly lower price of C$46.71. If you prioritise a blend of aesthetic appeal and cooling efficiency, the Peerless Assassin is the way to go. However, if you seek a reliable cooler that fits a broader range of sockets with a more understated look, the Phantom Spirit is an excellent choice.
