Price Comparison
The Thermalright AXP90-X53 is priced at $19.39, making it about 17% cheaper than the Thermalright Assassin X 120R, which costs $22.90. This price difference may appeal to budget-conscious consumers looking for an effective cooling solution without breaking the bank. While both coolers come from the same brand and feature advanced technology, the lower price of the AXP90-X53 could make it a more attractive option for those who prioritize cost-effectiveness in their CPU cooling solutions.
Design and Aesthetics
In terms of design, the Thermalright Assassin X 120R features a digital screen top cover and ARGB lighting, providing a visually striking appearance that enhances any build. The ARGB synchronization with the motherboard allows for customizable lighting effects that can match the user's setup. On the other hand, the AXP90-X53 has a more understated look with its white finish, making it suitable for minimalist builds. However, it lacks the advanced lighting features of its counterpart. If aesthetics and lighting are paramount, the Assassin X 120R stands out.
Cooling Performance
The Thermalright Assassin X 120R boasts a fan speed of 2000 RPM and utilizes four heat pipes to provide efficient cooling, which is essential for high-performance CPUs. Its AGHP heat pipe technology enhances heat dissipation, making it effective for demanding tasks. The AXP90-X53, while slightly shorter at 53mm, also features four heat pipes and a higher fan speed of 2700 RPM, which can translate into competitive cooling performance. However, its maximum TDP is rated at 150W, whereas the Assassin X 120R does not specify a TDP, indicating it may handle more demanding processors better.
Noise Levels
Noise levels are a crucial factor for gamers and professionals alike. The AXP90-X53 operates at a low noise level of 22.4 dBA, which is beneficial for users looking for a quiet environment. The Assassin X 120R, while equipped with a PWM fan that adjusts based on temperature, does not specify its noise level. The quieter operation of the AXP90-X53 makes it an excellent choice for compact builds or home theaters where noise can be disruptive.
Compatibility
Compatibility is another important factor to consider. The Thermalright Assassin X 120R is compatible with a wide range of sockets, including AM4, AM5, and various Intel LGA options. Its height of 151mm ensures it fits in most cases without compromising performance. Conversely, the AXP90-X53 is designed for low-profile builds, making it ideal for small form factor cases. It also supports the same range of sockets, but its 53mm height allows it to fit in tighter spaces. Users with smaller cases would benefit more from the AXP90-X53, while those with standard builds may prefer the versatility of the Assassin X 120R.
Installation Process
The installation process can vary between coolers. Both the Thermalright Assassin X 120R and the AXP90-X53 come with the necessary mounting hardware. The Assassin X 120R includes detailed instructions for easy installation, while the AXP90-X53 offers additional resources like installation videos, particularly beneficial for novice builders. This focus on user-friendliness in both products ensures that users of all skill levels can install their chosen cooler without much hassle.
Brand Reputation
Thermalright has established a solid reputation in the CPU cooler market, known for its innovative products and reliable performance. Both coolers are backed by the same brand, which assures customers of quality and performance. The Assassin X 120R, with its advanced features, is likely to attract enthusiasts and gamers, while the AXP90-X53 appeals to users seeking budget-friendly options without sacrificing quality. Brand loyalty and past experiences may influence buyers' decisions, but both products stand out due to their reliability.
Which should you buy?
Choosing between the Thermalright Assassin X 120R and the AXP90-X53 ultimately depends on your specific needs. If you're looking for a visually striking cooler with advanced features, the Assassin X 120R is a great choice despite its higher price. However, if you prioritize budget and compact design, the AXP90-X53's lower height and price make it an excellent option for smaller builds. Each product has distinct advantages, so consider your requirements and preferences before making a decision.
