Weighing 0.52 kg and measuring 120mm in length, 73mm in width, and 148mm in height, this air cooler is designed for easy installation in medium-sized cases.
With a PWM fan that can reach speeds of 1550 RPM and generate an airflow of 66.17 CFM, it operates at a noise level of 25.6 dB(A), making it a quiet choice for users seeking efficient cooling. The cooler supports a variety of CPU sockets, including Intel 115X/1200/1700 and AMD AM4/AM5, which enhances its versatility.
Overview of the Thermalright Royal Pretor 130 Ultra White CPU Cooler
The Thermalright Royal Pretor 130 Ultra White CPU Cooler is a more premium option priced at C$95.14. It features a dual tower design that enhances heat dissipation, making it ideal for high-performance builds. With dimensions of 130mm in width, 140mm in depth, and 158mm in height, this cooler is slightly bulkier than the Assassin King, weighing significantly more due to its robust construction.
Equipped with an innovative 7 heat pipe system made from pure copper, the Royal Pretor aims to provide superior thermal performance. The dual fans can operate at speeds up to 2150 RPM, generating an impressive airflow of 69 CFM, while keeping noise levels under 27 dB(A). It also supports a wide range of CPU sockets, including various Intel and AMD options.
Cooling Performance Comparison
In terms of cooling efficiency, the Royal Pretor 130 outshines the Assassin King 120. The Royal Pretor utilises a 7 heat pipe technology, which enhances its ability to dissipate heat compared to the 5 heat pipes in the Assassin King. This difference is crucial for users with higher TDP CPUs, as the Royal Pretor is designed to handle more demanding thermal loads.
While the Assassin King achieves a maximum airflow of 66.17 CFM with its single fan, the Royal Pretor's dual fan configuration allows it to reach up to 69 CFM. The operating noise levels of both coolers are comparable, with the Royal Pretor only slightly louder at a maximum of 27 dB(A). Therefore, if cooling performance is your primary concern, the Royal Pretor is the preferable choice.
Design and Aesthetics
The design of both coolers reflects Thermalright's commitment to quality. The Assassin King features an ARGB fan that not only provides effective cooling but also adds a visual appeal to your build. Its compact size allows it to fit into various cases without issue.
On the other hand, the Royal Pretor stands out with its dual tower design and striking ultra-white finish. This cooler is designed to offer a larger heat dissipation area, making it more efficient while still looking sleek. The combination of aluminum and copper materials in the Royal Pretor enhances both durability and aesthetic appeal. Users looking for a visually striking cooler might prefer the Royal Pretor, whereas those on a budget might appreciate the practical design of the Assassin King.
Installation and Compatibility
Both coolers offer easy installation processes, but there are notable differences in compatibility. The Assassin King supports Intel sockets 115X/1200/1700 and AMD AM4/AM5, making it a versatile choice for most mid-range setups. Its lightweight design further simplifies the installation process.
Conversely, the Royal Pretor offers broader compatibility, supporting various Intel sockets including LGA 2011 and LGA 2066, along with AMD AM4 and AM5. The inclusion of corresponding mounting hardware makes installation straightforward, but its larger size may require more consideration regarding case compatibility. For users with specific CPU needs or those looking to future-proof their builds, the Royal Pretor may provide a more comprehensive solution.
Noise Levels
When it comes to noise levels, both coolers perform admirably. The Assassin King operates at a maximum of 25.6 dB(A), making it one of the quieter options available. This low noise level is ideal for users who prioritize a silent computing experience.
The Royal Pretor, while slightly louder at a maximum of 27 dB(A), still maintains an acceptable noise level for most users. The improved cooling performance of the Royal Pretor may justify the marginal increase in noise for those who require enhanced thermal management. For users sensitive to noise, the Assassin King may be the better pick, but for those seeking superior cooling capabilities, the Royal Pretor's performance may outweigh its slight increase in noise.
