Price Comparison
The Thermalright Assassin X 120R SE V2 is priced at C$23.59, while the Cooler Master Hyper 212 RGB Black Edition costs C$44.99. This makes the Thermalright option significantly more budget-friendly, appealing to users who are looking for effective cooling without breaking the bank. With a price difference of C$21.40, the Thermalright cooler offers a compelling choice for cost-conscious consumers. In contrast, the Cooler Master cooler's higher price may reflect its advanced features and branding, which could justify the investment for some users.
Cooling Performance
Both coolers are designed to provide efficient cooling but have different approaches. The Thermalright Assassin X 120R SE V2 utilises four 6mm heat pipes and features a fan capable of delivering an airflow of 66.17 CFM at a noise level of 25.6 dB(A). This suggests that it can maintain a quieter operation while effectively dissipating heat. On the other hand, the Cooler Master Hyper 212 RGB Black Edition employs direct contact technology with four heat pipes and achieves an airflow of 57.3 CFM with a noise level of 26.0 dB. While both coolers offer solid performance, the Thermalright’s higher airflow and lower noise level may better suit users prioritising silent operation.
Design and Aesthetics
In terms of design, the Cooler Master Hyper 212 RGB Black Edition stands out with its RGB LED controller, allowing users to customise colours and effects. This feature adds a visual flair to any build, making it attractive for users who enjoy personalising their system. The Thermalright Assassin X 120R SE V2, while not equipped with RGB lighting, is designed with an efficient layout and a height of 148mm, ensuring compatibility with medium-sized cases. Users who value aesthetics may lean towards the Cooler Master for its lighting options, while those focused on performance and space might prefer the Thermalright’s more utilitarian design.
Noise Levels
Noise levels are crucial for many users, especially those in quiet environments. The Thermalright Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A), making it a quieter option compared to the Cooler Master Hyper 212 RGB Black Edition, which has a noise level of 26.0 dB. While the difference in noise is minimal, every decibel counts for users aiming for a silent PC build. The slightly lower noise level of the Thermalright could be a deciding factor for gamers or professionals who require a quiet workspace.
Installation and Compatibility
Installation ease and compatibility are essential factors when choosing a CPU cooler. The Thermalright Assassin X 120R SE V2 supports a wide range of CPU sockets, including Intel's LGA1150/1151/1155/1156/1200/1700 and AMD's AM4/AM5. It also includes detailed installation instructions and a video, making it accessible for users of all experience levels. The Cooler Master Hyper 212 RGB Black Edition features a snap-and-play intuitive fan bracket that simplifies upgrades and removal. While both coolers are designed for easy installation, the Thermalright's comprehensive compatibility may appeal more to users with varied setups.
Brand Reputation
Brand reputation plays a significant role in consumer decisions. Thermalright has over 20 years of experience in the cooling market and is known for its focus on research and development of computer accessories. In contrast, Cooler Master is a well-established brand with a strong following, particularly in the gaming community. While both brands have solid reputations, users may gravitate towards Cooler Master for its extensive range of products and established presence in the RGB market.
Features and Technology
The Thermalright Assassin X 120R SE V2 boasts advanced AGHP technology to combat the inverse gravity effect, ensuring consistent cooling performance regardless of orientation. Its S-FDB bearings promise a long service life for the cooler. Meanwhile, the Cooler Master Hyper 212 RGB Black Edition's direct contact technology enhances heat dissipation, and its smart fan sensor provides jam protection, preventing cable snagging. These specific features highlight the technological advancements in each cooler, with the Thermalright focusing on longevity and consistent performance, while Cooler Master prioritises user convenience and aesthetics.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE V2 and the Cooler Master Hyper 212 RGB Black Edition largely depends on your priorities. If budget, noise level, and cooling efficiency are your main concerns, the Thermalright cooler is an excellent choice at C$23.59, offering superior airflow and quieter operation. However, if aesthetics and ease of installation are important to you, and you are willing to invest more, the Cooler Master Hyper 212 RGB Black Edition at C$44.99 may be worth the additional cost for its RGB features and user-friendly design. Ultimately, both coolers deliver solid performance, so your decision should align with your specific needs and preferences.
