Price Comparison

When considering value, the Thermalright Assassin X120 SE ARGB CPU Air Cooler stands out with a price of £16.29, significantly lower than the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler, which is priced at £41.90. This nearly £25 difference makes the Assassin X120 SE a more budget-friendly option for users seeking effective cooling without breaking the bank. Despite the lower price, the Assassin X120 SE does not compromise on performance, making it an appealing choice for gamers and PC builders alike.

Size and Design

The Thermalright AXP90-X47 is designed for compact builds, with dimensions of 94.5×95×47mm, making it ideal for small form factor systems. In contrast, the Thermalright Assassin X120 SE has a larger footprint at 120(L)x71(W)x148(H)mm, which suits medium-sized computer cases. The AXP90-X47's low profile is particularly beneficial for users with limited space, while the Assassin X120 SE’s size allows for more robust cooling capabilities. This difference in size means the AXP90-X47 is tailored for compact ITX setups, whereas the Assassin X120 SE is better for standard builds where space is less of a constraint.

Cooling Performance

The Thermalright AXP90-X47 boasts a maximum air volume of 42.58 CFM and operates at a fan speed of 2700 RPM, generating a noise level of just 22.4 dB(A). This makes it an excellent choice for users who prioritise quiet operation alongside effective cooling. On the other hand, the Assassin X120 SE offers a higher maximum air flow of 66.17 CFM, albeit at a slightly louder 25.6 dB(A). This indicates that while both coolers are effective, the Assassin X120 SE may provide superior cooling performance at the cost of increased noise, catering to users who require optimal cooling in larger systems.

Build Quality and Materials

Both coolers showcase Thermalright's commitment to quality through their materials. The AXP90-X47 features a pure copper radiator, which enhances heat transfer efficiency and oxidation resistance. In comparison, the Assassin X120 SE utilises an aluminium heat sink, which is lightweight and effective but may not match the thermal conductivity of copper. The AXP90-X47's plating anti-oxidation layer adds an extra level of durability, while the Assassin X120 SE’s use of high-quality PBT + PC materials contributes to its overall sturdiness. Users who value premium materials for longevity and performance may lean towards the AXP90-X47 despite the price difference.

Fan Technology

The fan technology used in both coolers is noteworthy. The AXP90-X47 includes a TL-9015R fan that operates quietly at a maximum speed of 2700 RPM. In contrast, the Assassin X120 SE features a TL-C12C-S fan that runs at 1550 RPM, which is lower but offers vibrant ARGB lighting effects. This visual appeal can enhance the overall aesthetics of a build, particularly for gamers who appreciate RGB features. While the AXP90-X47 focuses more on cooling efficiency and noise reduction, the Assassin X120 SE balances decent cooling with eye-catching design, catering to a different segment of users.

Compatibility

Both coolers are compatible with a range of Intel and AMD sockets, making them versatile choices for various builds. The AXP90-X47 supports sockets including Intel LGA 1700 and AMD AM4/AM5, ensuring broad compatibility for modern systems. Similarly, the Assassin X120 SE also supports a variety of Intel sockets (including LGA 1700) and AMD AM4/AM5. This compatibility means that either cooler can accommodate a wide range of processors, giving users flexibility when choosing their CPU and ensuring that both coolers can fit into many setups.

Noise Levels

Noise is a critical factor for many users when selecting a CPU cooler. The Thermalright AXP90-X47 operates at a maximum noise level of 22.4 dB(A), which is quite low and ideal for quiet environments. The Assassin X120 SE, while slightly louder at 25.6 dB(A), still maintains a relatively quiet operation given its higher air flow. For users who prioritise a silent system, the AXP90-X47 is likely the better choice; however, the Assassin X120 SE provides a balance of noise and cooling efficiency, making it suitable for those who can tolerate a bit more sound for enhanced performance.

Which should you buy?

Choosing between the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler and the Thermalright Assassin X120 SE ARGB CPU Air Cooler ultimately depends on your specific needs and build. If you are looking for a compact cooler that excels in quiet operation and premium materials, the AXP90-X47 is worth the extra investment at £41.90. However, if you desire a more budget-friendly option with vibrant ARGB aesthetics and strong cooling performance, the Assassin X120 SE at £16.29 is an excellent choice. Each cooler has its strengths, so your decision should align with your priorities—be it space constraints, noise levels, or visual appeal.
