Price Comparison
The Thermalright Assassin X 90 SE V2 is priced at C$24.90, while the Thermalright Royal Pretor 130 Ultra White comes in at a significantly higher C$95.14. This price difference of C$70.24 makes the Assassin X 90 SE V2 an attractive option for budget-conscious consumers looking for effective CPU cooling solutions without breaking the bank. The substantial price disparity raises questions about the features and performance offered by each cooler, making it essential to delve deeper into their specifications and capabilities.
Design and Build Quality
In terms of design, the Thermalright Royal Pretor 130 Ultra White boasts a larger size at 130x140x158mm compared to the Assassin X 90 SE V2's more compact dimensions of 94x77x118mm. The Royal Pretor's twin tower radiator design, combined with an aluminum and copper heat sink, aims to maximise heat dissipation. In contrast, the Assassin X 90 SE V2 utilises a single tower design made primarily of aluminum. The increased height and dual fans of the Royal Pretor may offer enhanced cooling performance, particularly for overclocked CPUs, while the Assassin X 90 SE V2's smaller footprint allows for compatibility with more chassis models.
Cooling Performance
The cooling performance of the Thermalright Royal Pretor 130 Ultra White is highlighted by its 7x6mm pure copper heat pipes, which are designed to efficiently manage heat dissipation. This model offers a maximum airflow of 81.88 CFM and operates at a noise level of less than 28.3 dB(A). In comparison, the Assassin X 90 SE V2 features a 4x6mm heat pipe configuration and achieves an airflow of 32.77 CFM with a maximum noise level of 23.85 dB(A). While the Royal Pretor excels in airflow and heat dissipation, the Assassin X 90 SE V2 delivers quieter operation, making it suitable for users prioritising a low-noise environment.
Fan Specifications
The fan specifications of both coolers reveal significant differences in design and performance. The Royal Pretor features dual fans with varied speeds of up to 2150 RPM and 1750 RPM, providing adjustable airflow capabilities of 69 and 81.88 CFM, respectively. In contrast, the Assassin X 90 SE V2 is equipped with a single PWM fan that operates at a maximum speed of 2200 RPM and delivers a consistent airflow of 32.77 CFM. The dual-fan setup of the Royal Pretor may provide superior cooling for high-performance setups, while the single fan of the Assassin X 90 SE V2 may appeal to users seeking simplicity and ease of installation.
Compatibility
Both coolers offer broad compatibility with various CPU socket types. The Thermalright Assassin X 90 SE V2 supports Intel socket types 1150, 1151, 1155, 1156, and 1200, as well as AMD AM4 and AM5.
