Price Comparison
The Thermalright Royal Pretor 130 CPU Cooler is priced at C$66.90, while the Thermalright Assassin X 120 SE CPU Air Cooler is significantly more affordable at C$25.59. This substantial price difference makes the Assassin X an attractive option for budget-conscious consumers looking for decent cooling performance without breaking the bank. The Royal Pretor, however, justifies its higher price with advanced features and potentially superior cooling capabilities, appealing to enthusiasts and gamers who are willing to invest more for better performance.
Design and Build Quality
The Royal Pretor 130 features a robust twin-tower radiator design, measuring 130x140x158mm, which optimises heat dissipation through its 6x6mm pure copper heat pipes. This construction is aimed at achieving maximum thermal performance, while the use of aluminum and copper in its build enhances durability. In contrast, the Assassin X 120 SE has a slightly smaller footprint at 125x71x148mm and utilises a more traditional single-tower design. While both coolers are made with industrial strength materials, the Royal Pretor’s twin-tower design may offer better cooling efficiency, especially under load.
Cooling Performance
The Royal Pretor 130 employs a 6 heat pipe technology that is designed to efficiently manage CPU temperatures by quickly transferring heat away from the chip. This cooler can handle high thermal loads effectively, making it suitable for high-performance CPUs. The Assassin X 120 SE, featuring 4 heat pipes and a TDP rating of 125 to 225W, also provides solid cooling performance suitable for mid-range systems. However, the advanced design of the Royal Pretor suggests it may perform better under extreme conditions, particularly for overclocked setups.
Noise Levels
Noise levels are an important consideration for many PC builders, and both coolers feature design elements aimed at reducing operational noise. The Royal Pretor includes soft silicone corner pads to minimise vibration and noise, contributing to a quieter operation. The Assassin X 120 SE is designed with a PWM fan that operates at a maximum noise level of 25.6 dB(A), ensuring it runs quietly even at full speed. Generally, both coolers deliver efficient cooling with a focus on low noise, but the Royal Pretor may have a slight edge in noise reduction due to its more advanced construction.
Compatibility
Compatibility is essential when selecting a CPU cooler, and both models offer wide-ranging support for various platforms. The Royal Pretor 130 is compatible with a range of AMD and Intel sockets, including AM4/AM5 and Intel LGA 1700/1156/1200, among others. The Assassin X 120 SE supports similar Intel and AMD sockets, including 115X and AM4. Both coolers come with the necessary mounting hardware for easy installation, but the Royal Pretor’s broader compatibility may make it a better choice for users with specific motherboard setups.
Installation Process
The installation process for both coolers is designed to be user-friendly. The Royal Pretor 130 comes with specific mounting grommets and an installation guide, which is particularly helpful for less experienced builders. Additionally, it includes a Y-adapter cable for connecting to motherboard fan headers, preventing issues with insufficient ports. The Assassin X 120 SE also provides metal fasteners for easy installation on Intel and AMD platforms. While both coolers simplify the installation process, the Royal Pretor’s additional features may enhance ease of use for those new to PC building.
Aesthetic Appeal
The visual design of a CPU cooler can also influence buying decisions. The Royal Pretor 130 has a more striking aesthetic with its twin-tower design and premium materials, making it an eye-catching addition to any rig, especially for gamers and enthusiasts who showcase their builds. The Assassin X 120 SE, while functional, has a simpler design that might not appeal to users looking for a standout cooler. Those prioritising aesthetics alongside performance may lean towards the Royal Pretor for its more elaborate look.
Which should you buy?
Ultimately, the decision between the Thermalright Royal Pretor 130 and the Thermalright Assassin X 120 SE depends on your specific needs and budget. If you are seeking the best performance and are willing to invest more, the Royal Pretor 130 offers superior cooling capabilities, advanced technology, and an aesthetically pleasing design at a price of C$66.90. On the other hand, if you are on a tighter budget and need a reliable cooler for standard gaming or moderate workloads, the Assassin X 120 SE at C$25.59 provides excellent value without compromising too much on performance.
