Overview of Thermalright AXP90 X47 and Thermalright Peerless Assassin 120 Digital
When comparing the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler, the key takeaway is that the AXP90 X47 is designed for compact builds, while the Peerless Assassin offers superior cooling performance for larger systems. The AXP90 X47 is priced at $33.99, making it about 26% cheaper than the Peerless Assassin, which retails for $45.90. This price difference highlights the focus of each cooler on different user needs and system configurations.
Design and Build Quality
In terms of design, the Thermalright AXP90 X47 features an ultra-compact low-profile design with a total height of just 47mm. This makes it ideal for small form factor builds where space is a premium. In contrast, the Thermalright Peerless Assassin stands significantly taller at 162mm, indicating a more robust design suited for larger cases. The Peerless Assassin’s dual tower configuration and magnetic top cover enhance its aesthetic appeal and functionality. Both coolers utilize high-quality materials, but their designs cater to different types of builds, with the AXP90 X47 being more versatile for tight spaces.
Cooling Performance
Cooling performance is where the Thermalright Peerless Assassin truly shines. It boasts six pure copper heat pipes and a dual fan setup that allows for an impressive air volume of 88.89 CFM. This enables it to dissipate heat effectively, especially under heavy loads. The AXP90 X47, while equipped with four heat pipes and a single 92mm PWM fan that delivers a lower airflow of 42.58 CFM, is still commendable for its size. However, in terms of raw cooling capability, the Peerless Assassin is the clear winner, providing better heat dissipation and overall performance.
Noise Levels
Noise levels are an important consideration for many users, and both coolers perform admirably in this regard. The AXP90 X47 operates at a noise level of 22.4 dB(A), which is quite low and ensures a quiet computing experience. The Peerless Assassin, although slightly louder at up to 25.6 dB(A), still maintains a relatively quiet operation given its higher performance. The difference in noise output is minimal, but the AXP90 X47 may appeal more to users who prioritize silence over cooling power.
Compatibility
When it comes to compatibility, both products offer broad support for various CPU sockets. The Thermalright AXP90 X47 is compatible with Intel LGA 1150/1151/1155/1156/1200/1700 and AMD AM4 sockets, making it versatile for many builds. The Thermalright Peerless Assassin matches this compatibility and goes a step further by supporting AMD AM5 and Intel LGA 1851, ensuring it can accommodate the latest processors. This wider compatibility might give the Peerless Assassin an edge for future-proofing, especially for users looking to upgrade their systems.
Installation Process
The installation process is an important factor for users who may not have extensive building experience. The AXP90 X47, with its compact design, can be easier to install in tight spaces. However, the Peerless Assassin, with its dual fans and larger size, may require a bit more effort during installation. Both coolers come with mounting clips for various platforms, ensuring they can be installed correctly. That said, the AXP90 X47's simpler design could be more approachable for novice builders.
Aesthetic Appeal
Aesthetic appeal is subjective, but it plays a significant role in consumer preference. The Thermalright Peerless Assassin features a modern digital screen and ARGB lighting, giving it a contemporary look that can enhance the visual appeal of a gaming rig. In contrast, the AXP90 X47 has a more utilitarian design, prioritizing functionality over flashiness. Users who value RGB lighting and a sleek appearance may lean towards the Peerless Assassin, while those looking for a straightforward, effective cooler might prefer the AXP90 X47.
Which should you buy?
