The Thermalright AXP90 X36 is priced at $20.39, making it about 56% cheaper than the Thermalright Peerless Assassin 120, which retails for $45.90. While the AXP90 X36 is designed for compact spaces, the Peerless Assassin 120 offers enhanced cooling performance with its dual-tower design and additional features. Understanding the strengths of each product can help consumers decide which cooler best meets their needs.
Design and Build Quality
The Thermalright AXP90 X36 features a low-profile design with a total height of just 36mm, making it ideal for small form factor builds. Its all-metal platform and back plate fastener enhance durability and stability. In contrast, the Peerless Assassin 120 boasts a larger footprint with an overall height of 162mm, incorporating a dual tower design and a digital screen top cover. This combination not only adds to its aesthetic appeal but also improves heat dissipation capabilities. The noticeable difference in size could be a key factor for users with space constraints.
Cooling Performance
The AXP90 X36 utilizes 4×6mm AGHP heat pipes, providing adequate cooling with a noise level of just 22.4 dBA. While it is efficient for its size, the cooling performance may not match that of the Peerless Assassin 120, which features 6 heat pipes and a fan speed of 1850 RPM. This model also claims to handle a maximum air volume of 88.89 CFM, which suggests superior cooling efficiency. Users requiring high-performance cooling for demanding applications may prefer the enhanced capabilities of the Peerless Assassin 120.
Compatibility
The AXP90 X36 supports a range of platforms, including AMD AM4/AM5 and Intel LGA1150/1151/1200/1700/1851. This makes it a versatile option for many users.
