Overview of the Coolers
The Thermalright Peerless Assassin 120 SE CPU Cooler and the Thermalright Phantom Spirit 120 SE Black CPU Cooler are both solid options for users looking to enhance their CPU cooling performance. The Peerless Assassin is priced at $49.99, while the Phantom Spirit is approximately 17% cheaper at $39.90. Despite the price difference, both products provide reliable cooling solutions with distinct features.
Cooling Technology
The Peerless Assassin utilizes 6 heat pipes with AGHP technology, designed to minimize the inverse gravity effect during operation. This ensures optimal heat dissipation, making it particularly effective for high-performance CPUs. In contrast, the Phantom Spirit boasts 7 heat pipes that also employ AGHP technology, enhancing its heat dissipation even further. With a slightly better design, the Phantom Spirit aims to maximize the effective heat dissipation area, which can result in better overall cooling efficiency.
Fan Performance
Both coolers come equipped with dual PWM fans. The Peerless Assassin features TL-C12C fans that can reach speeds of up to 1550 RPM, while the Phantom Spirit's TL-C12B V2 fans operate at a maximum speed of 1500 RPM. Despite the minor difference in speed, both fans generate a comparable airflow of 66.17 CFM and maintain a noise level of about 25.6 dB(A). Users can expect similar acoustic performance from both coolers, making either choice suitable for a quiet computing environment.
Build Quality and Design
In terms of build quality, the Peerless Assassin is made with aluminum and includes a copper base for enhanced thermal conductivity. The Phantom Spirit, on the other hand, features a blackened nano coating and a finely carved copper base, which not only improves cooling performance but also offers a sleek aesthetic. The dimensions of both coolers are quite similar, with the Peerless Assassin measuring 125mm x 135mm x 155mm and the Phantom Spirit at 125mm x 135mm x 154mm. Both designs are compact, making them suitable for most PC cases.
Compatibility
Compatibility is crucial when selecting a CPU cooler, and both coolers support a range of socket types. The Peerless Assassin is compatible with Intel LGA 1700/1150/1151/1200/1851 and AMD AM4/AM5. The Phantom Spirit supports a similar range, including Intel LGA 1851/1700/115X/1200 and AMD AM4/AM5. Both coolers come with the necessary mounting hardware for different platforms, although users should note that for AMD installations, using the motherboard's built-in backplane is required.
Cooling Performance
The cooling performance of both models is impressive, but there are some distinctions. The Peerless Assassin's 6 heat pipes work in conjunction with its PWM fans to provide reliable cooling for demanding CPUs. Conversely, the Phantom Spirit’s 7 heat pipes and advanced design might offer it a slight edge in thermal performance, particularly under heavy loads. Users looking for extreme cooling may find the Phantom Spirit to be a more appealing option overall.
Price Comparison
Price can often be a deciding factor, and in this case, the Phantom Spirit is more budget-friendly at $39.90 compared to the Peerless Assassin's $49.99. This price difference of about $10 could be significant for users who are price-sensitive. Given that both products offer similar features and performance, the Phantom Spirit provides a compelling value proposition without sacrificing quality.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the Thermalright Phantom Spirit 120 SE Black ultimately depends on your specific needs and budget. If you prioritize top-tier cooling performance and don’t mind spending a bit more, the Peerless Assassin could be the way to go. However, for those who are looking for a great value without compromising on performance, the Phantom Spirit is an excellent choice with its lower price and solid cooling capabilities.
