The Thermalright Peerless Assassin 120 SE ARGB focuses on providing a balance of performance and aesthetics with its ARGB lighting, while Noctua's NH-D15S chromax.Black prioritises high compatibility and quiet operation, reinforced by a solid six-year warranty.
Design & Aesthetics
When it comes to design, the Thermalright Peerless Assassin 120 SE ARGB features a sleek, dual-tower design complemented by colourful ARGB lighting effects. This cooler measures 125mm x 135mm x 155mm and weighs approximately 0.97 kg, making it a compact yet powerful option.
On the other hand, the Noctua NH-D15S chromax.Black sports an all-black design that fits well with various build aesthetics. Its asymmetrical single-fan design allows for dual-tower performance while maintaining compatibility with most tower cases. With a height of 160mm, it provides excellent cooling performance without blocking PCIe slots, making it an excellent choice for high-performance setups.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 120 SE ARGB is equipped with advanced AGHP technology and six copper heat pipes, allowing it to handle a TDP of 120 to 245W. This means it is ideal for users looking to push their CPUs to the limit. The two PWM fans operate at a maximum speed of 1,500 RPM and can generate an airflow of up to 66.17 CFM with a noise level of ≤25.6 dB(A).
Conversely, the Noctua NH-D15S chromax.Black utilises a renowned NF-A15 140mm fan that offers whisper-quiet operation at idle and full performance under load. The cooler's efficient design allows it to maintain excellent temperatures, especially for high-end CPUs like the AMD Ryzen 9 series and Intel Core Ultra processors.
