Dimension comparison
Design and build quality
The Thermalright Peerless Assassin 120 SE V3 features a double-tower dual-fan structure with a blackened anodic matte top sheet. It utilizes a Seiko micro-carved reflow soldering nickel-plated copper bottom to ensure efficient heat transfer from the processor. In comparison, the Thermalright PS120SE CPU Air Cooler, 7 focuses on industrial strength materials, using PBT plus PC material for high-quality construction. Both coolers adopt aluminium heatsink materials, ensuring a balance between weight and thermal conductivity. The build quality on both units reflects Thermalright's history of over 20 years in the cooler market.
Cooling technology and heat pipes
A key differentiator lies in the heat pipe configuration. The Thermalright Peerless Assassin 120 SE V3 employs 6 fully electroplated anti-oxidation heat pipes. Conversely, the Thermalright PS120SE CPU Air Cooler, 7 utilizes 7x6mm heat pipes with AGHP upgraded 4th generation technology. This AGHP technique addresses inverse gravity effects caused by vertical or horizontal orientation, potentially improving reliability across different case layouts. The additional heat pipe on the Thermalright PS120SE CPU Air Cooler, 7 suggests a theoretical advantage in raw heat dissipation capacity.
Fan performance and airflow
Regarding airflow, the Thermalright Peerless Assassin 120 SE V3 provides specific metrics, boasting an air volume of 70.84CFM. It includes 120mm performance dual fans capable of up to 2000RPM. The fan interface is a standard 4PIN PWM, allowing for automatic speed adjustment according to motherboard temperature. While the Thermalright PS120SE CPU Air Cooler, 7 also utilizes dual fans, the provided data does not explicitly list the CFM or RPM specifications. However, both units are designed to bring good heat dissipation effects through large air volume.
Compatibility and dimensions
Physical compatibility is crucial for CPU coolers. The Thermalright Peerless Assassin 120 SE V3 measures 125x135x155mm. The Thermalright PS120SE CPU Air Cooler, 7 is slightly shorter with a height of 154mm, measuring 125(L)x135(W)x154(H)mm. This 1mm difference is negligible for most chassis, but the Thermalright PS120SE CPU Air Cooler, 7 notes compatibility with a wide range of chassis models due to its 154mm height. Both coolers fit within standard mid-tower and full-tower case limitations, ensuring broad system compatibility.
Thermal performance and TDP
Thermal handling capability is a major specification for enthusiasts. The Thermalright PS120SE CPU Air Cooler, 7 explicitly states a CPU cooler TDP range of 105W to 280W. This provides users with a clear understanding of the processor loads it can handle. The Thermalright Peerless Assassin 120 SE V3 describes its ability to easily dissipate CPU temperature but lacks a specific numerical TDP rating in the provided data. For users planning to push high-wattage processors, the explicit 280W rating of the Thermalright PS120SE CPU Air Cooler, 7 offers greater confidence.
Noise levels and acoustics
Acoustic performance is vital for a quiet computing environment. The Thermalright Peerless Assassin 120 SE V3 specifies an operating noise level of ≤29.8db(A). This quantifiable metric allows users to gauge expected acoustic output accurately. The Thermalright PS120SE CPU Air Cooler, 7 mentions an industrial service life of up to 20000 hours but does not provide a specific decibel rating in the available specifications. For noise-conscious builders, the documented low noise figure of the Thermalright Peerless Assassin 120 SE V3 is a distinct advantage.
Price and value
Both coolers are positioned at the same price point of $35.90. This parity makes the decision purely dependent on feature sets rather than budget constraints. Given the identical cost, the Thermalright PS120SE CPU Air Cooler, 7 offers value through its higher heat pipe count and AGHP technology. However, the Thermalright Peerless Assassin 120 SE V3 offers value through verified performance metrics like airflow and noise. Both represent strong value propositions in the budget air cooler segment, delivering dual-tower performance without premium pricing.
Which one should you buy?
Choosing between these models depends on your priority between verified metrics and raw cooling hardware. If you prioritize documented airflow and noise levels, the Thermalright Peerless Assassin 120 SE V3 is the logical choice. However, if maximum heat pipe density and explicit TDP support are your main concerns, the Thermalright PS120SE CPU Air Cooler, 7 takes the lead. Considering the upgraded AGHP technology and 7 heat pipes at the same price, the Thermalright PS120SE CPU Air Cooler, 7 is recommended for most users seeking thermal headroom.
