Dimension comparison
Overview
When it comes to choosing a CPU cooler, the Thermalright AXP90 X47 Black Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler offer distinct features and capabilities to cater to different needs. The AXP90 X47 is priced at $22.39, while the Peerless Assassin is significantly more expensive at $45.90, making it about 105% pricier. Understanding the differences between these two products can help you decide which one is best suited for your setup.
Design and Build Quality
The design of the Thermalright AXP90 X47 emphasizes compactness, featuring a low-profile height of just 47mm. This makes it an excellent choice for small form factor builds, such as ITX cases. In contrast, the Thermalright Peerless Assassin stands taller at 162mm, showcasing a dual tower design that allows for enhanced heat dissipation through six heat pipes. The AXP90 X47 is crafted with a black nickel plating process that enhances its corrosion resistance, while the Peerless Assassin incorporates a sleek digital screen top cover for a modern aesthetic. The difference in design means that the AXP90 X47 is ideal for space-constrained environments, while the Peerless Assassin is better suited for larger cases with ample clearance.
Cooling Performance
Cooling performance is crucial when selecting a CPU cooler, and both models excel in their own right. The AXP90 X47 features four 6mm heat pipes and operates at a noise level of just 22.4 DBA, making it a quiet option for low-profile cooling. On the other hand, the Peerless Assassin boasts a fan speed of up to 1850 RPM and an air volume of 88.89 CFM, providing excellent heat dissipation capabilities, even under heavy loads. The AXP90 X47 is designed for compatibility with both Intel and AMD platforms, while the Peerless Assassin’s advanced AGHP technology optimizes thermal performance across dual platforms. Thus, if you prioritize performance in a compact form, the AXP90 X47 may suffice; however, for higher performance needs, especially in overclocking scenarios, the Peerless Assassin stands out.
Noise Levels
When it comes to noise levels, the Thermalright AXP90 X47 is notably quieter, operating at 22.4 DBA. This makes it an excellent choice for users who prefer a silent computing experience, particularly in small form factor builds where noise can be more pronounced. In contrast, the Peerless Assassin, while still relatively quiet, has a maximum operating noise of 25.6 DBA. The slight increase in noise may be a consideration for users looking for a noise-optimized cooling solution. Therefore, if silent operation is a priority, the AXP90 X47 has a clear advantage.
Compatibility
Compatibility is essential when selecting a CPU cooler, and both the AXP90 X47 and the Peerless Assassin offer broad support for various Intel and AMD platforms. The AXP90 X47 supports Intel sockets 115X/1200 and AMD AM4/AM5, making it versatile for many users. Meanwhile, the Peerless Assassin has even wider compatibility with Intel sockets LGA1851/1700/1150/1151/1155/1156/1200 and AMD AM4/AM5, which may cater to a larger audience. However, the larger size of the Peerless Assassin means it may not fit in more compact cases. Thus, while both coolers are compatible with multiple platforms, the choice may come down to the specific case size and configuration.
Installation Process
The installation process can vary significantly between CPU coolers, and ease of installation is a factor to consider. The Thermalright AXP90 X47 comes with an all-metal platform and backplate fastener, which simplifies the mounting process in compact spaces. Conversely, the Peerless Assassin, with its dual-fan setup and larger dimensions, may require a more involved installation, especially for those unfamiliar with CPU coolers. For users who prioritize straightforward installation, the AXP90 X47 offers a more user-friendly experience, while the Peerless Assassin may be better suited for those comfortable with more complex setups.
Aesthetic Features
Aesthetic appeal is another aspect where the two coolers diverge. The AXP90 X47 has a classic design that may blend well with minimalist builds, but it lacks RGB lighting or flashy features. In contrast, the Peerless Assassin includes a digital screen top cover and ARGB lighting, allowing for a more customizable and visually striking setup. If aesthetics are a significant part of your build, the Peerless Assassin’s modern design and lighting features make it a more attractive choice. However, if simplicity is your preference, the AXP90 X47’s understated look may align better with your vision.
Which should you buy?
Ultimately, the choice between the Thermalright AXP90 X47 Black Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler depends on your specific needs and preferences. If you require a compact, quiet, and budget-friendly CPU cooler for a small form factor build, the AXP90 X47 at $22.39 is an excellent option. On the other hand, if you seek high cooling performance, advanced features, and greater compatibility with larger cases, the Peerless Assassin at $45.90 is worth the investment. Each cooler excels in its domain, so consider your priorities carefully before making a decision.
