Price Comparison
When it comes to pricing, the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler is available for £41.90, while the TR-Peerless Assassin 120 Digital ARGB White CPU Cooler is slightly more affordable at £35.89. This difference of £6.01 may seem minor, but it can influence budget-conscious consumers who are seeking value without compromising performance. While both coolers are competitively priced, the TR-Peerless Assassin offers a more budget-friendly option, which may appeal to those looking to optimise their build without overspending.
Size and Design
In terms of size, the Thermalright AXP90-X47 has a compact design with dimensions of 94.5×95×47mm, making it an ideal choice for small form-factor builds such as ITX systems. In contrast, the TR-Peerless Assassin is significantly larger, measuring 138x125x162mm, designed for standard ATX cases. This larger size allows for dual fans and more effective cooling, which is essential for high-performance CPUs. Thus, if you have space constraints, the AXP90-X47 is the clear winner, but for overall cooling performance, the TR-Peerless Assassin has the advantage.
Cooling Performance
Cooling performance is crucial for any CPU cooler. The Thermalright AXP90-X47 features a maximum air volume of 42.58CFM and operates at a fan speed of 2700RPM with a noise level of 22.4dB(A). On the other hand, the TR-Peerless Assassin offers a greater air volume of 88.89CFM, with a fan speed of 1850RPM and a slightly higher noise level of up to 25.6dB(A). This suggests that while the AXP90-X47 is quieter, the TR-Peerless Assassin is designed for more aggressive cooling, making it the better choice for users with high-performance setups that require superior heat dissipation.
Fan Configuration
The fan configuration is another critical aspect to consider. The Thermalright AXP90-X47 utilises a single 92mm PWM fan, which is effective for its size but may limit airflow in larger builds. In contrast, the TR-Peerless Assassin is equipped with dual 120mm fans, which can significantly enhance cooling efficiency. This dual-tower design not only provides better airflow but also helps to dissipate heat more effectively, making it a more suitable option for overclocked systems or those running demanding applications. Therefore, for users who prioritise airflow and cooling capacity, the TR-Peerless Assassin is the superior choice.
Noise Levels
Noise levels can impact the overall user experience, especially in quiet environments. The Thermalright AXP90-X47 operates at a maximum noise level of 22.4dB(A), making it a relatively quiet option for a CPU cooler. The TR-Peerless Assassin, while slightly louder at 25.6dB(A), still falls within an acceptable range for most users. Those who are particularly sensitive to noise may prefer the quieter operation of the AXP90-X47, especially in compact builds where sound can be more pronounced. However, for users focused on performance, the slight increase in noise from the TR-Peerless Assassin may be an acceptable trade-off for its enhanced cooling capabilities.
Compatibility
Both coolers boast broad compatibility with various CPU sockets. The Thermalright AXP90-X47 supports Intel LGA 1700/1851/1150/1151/1155/1156/1200 and AMD AM4/AM5 sockets, making it versatile for many modern builds. The TR-Peerless Assassin also supports a similar range, including AMD AM4/AM5 and various Intel sockets. This compatibility means that both coolers can cater to most users, but the AXP90-X47 may appeal more to those building compact systems due to its low-profile design. Ultimately, the choice may depend on the user's specific motherboard and case requirements.
Installation Process
The installation process can vary significantly between different CPU coolers. The Thermalright AXP90-X47 is designed with ease of installation in mind, particularly for ITX builds where space is limited. Its low-profile design allows for straightforward mounting without interfering with RAM or other components. Conversely, the TR-Peerless Assassin, with its dual-tower design, may require a bit more effort to install due to its larger size and dual fans. However, its design also ensures that it fits securely and operates effectively once in place. Users should consider their comfort level with installation when choosing between the two coolers.
Which should you buy?
In conclusion, the choice between the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler and the TR-Peerless Assassin 120 Digital ARGB White CPU Cooler ultimately hinges on your specific needs. If you require a compact, low-profile cooler for an ITX build, the AXP90-X47 is a fantastic choice, particularly for its quieter operation and ease of installation. However, if you seek superior cooling performance and don’t mind a larger footprint, the TR-Peerless Assassin stands out with its dual fans and impressive airflow capabilities. Both coolers are competitively priced and offer excellent compatibility, making either a solid choice based on your individual requirements.
