Dimension comparison
Price Comparison
The upHere H45K6 Low Profile CPU Cooler is priced at C$49.99, while the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler is more affordable at C$29.90. This price difference of C$20.09 makes the Thermalright option appealing for budget-conscious consumers. However, the additional cost of the upHere cooler may be justified by its ultra-compact design and enhanced compatibility with Mini ITX cases.
Design and Dimensions
The upHere H45K6 features a low-profile design with a height of just 45mm, making it ideal for space-constrained builds. This compactness ensures that it can fit seamlessly into Mini ITX cases without compromising on performance. In contrast, the Thermalright Burst Assassin boasts a standard tower design, which may require more vertical space, though it does not specify its height. This design choice might limit its compatibility with smaller cases, making the upHere cooler a better option for users with limited space.
Cooling Performance
The cooling performance of the upHere H45K6 is defined by its six heat pipes that effectively manage a thermal dissipation capability of 150W TDP. This means it is well-equipped to handle mainstream CPUs under sustained workloads. Meanwhile, the Thermalright Burst Assassin features six nickel-plated pure copper heat pipes with an airflow of 66.17 CFM, which is higher than the upHere cooler’s 35.34 CFM. While the upHere cooler excels in compactness and specific design optimizations, the Thermalright's airflow may provide superior cooling in larger setups, depending on the configuration.
Noise Levels
In terms of noise levels, the upHere H45K6 operates at a maximum of 27 dB(A), ensuring that users can enjoy a quiet computing environment, especially in small builds. The Thermalright Burst Assassin, on the other hand, operates at a slightly lower noise level of 25.6 dB(A). Although the difference is minimal, the Thermalright cooler may offer a marginally quieter operation, which can be a significant factor for users prioritizing a silent system.
Compatibility
Compatibility is a strong point for both coolers. The upHere H45K6 supports a wide range of Intel and AMD sockets, including Intel LGA 1851, 1700, 115x, 1200, 2011, 2066, and AMD AM5, AM4, AM3. This broad compatibility ensures that users can install it across various builds without concerns about interference with RAM or motherboard heatsinks. The Thermalright Burst Assassin also supports numerous Intel and AMD sockets, including LGA1150, 1151, 1155, 1156, 1200, 1700, 1851, and AM4, AM5. However, it introduces a fin offset technology that claims to alleviate concerns over memory height limitations during installation, making it a versatile choice as well.
Installation Process
The installation process for both coolers is designed to be user-friendly. The upHere H45K6 features a tool-free installation process that can be completed in under five minutes, which is beneficial for users who prefer a quick setup. The Thermalright Burst Assassin is also designed for ease of installation, equipped with mounting plates and fasteners for various CPU socket platforms. While both coolers are easy to install, the upHere cooler’s rapid setup process gives it an edge for those looking to streamline their assembly.
Aesthetic Appeal
When it comes to aesthetics, the Thermalright Burst Assassin stands out with its ARGB lighting, allowing it to integrate stylishly into RGB-themed builds. This lighting feature adds a visual flair that can enhance the overall look of a system. In contrast, the upHere H45K6 does not mention any RGB features, focusing instead on its performance and compact design. For users who value aesthetics and want their cooler to match their build's lighting scheme, the Thermalright may be the preferred option.
Which should you buy?
Choosing between the upHere H45K6 Low Profile CPU Cooler and the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you require a compact cooler that fits in tight spaces and offers solid cooling performance, the upHere model is a strong contender. However, if you are looking for a budget-friendly option that combines good cooling performance with aesthetic appeal through ARGB lighting, the Thermalright cooler might be the better choice for you. Consider your system's requirements and personal preferences to make the best decision.
