Price Comparison
The Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler is priced at C$62.90, while the upHere H45K6 Low Profile CPU Cooler is more budget-friendly at C$49.99. This C$12.91 difference may influence buyers looking for cost-effective cooling solutions. While the Thermalright offers advanced features like ARGB lighting and a 240mm radiator, the upHere provides solid performance in a compact design, making it an excellent choice for those on a tighter budget or with space constraints.
Cooling Performance
When it comes to cooling performance, the Thermalright Frozen Notte boasts a high-performance cold head that operates at speeds of up to 5300 RPM. This, combined with its dual PWM fans that can reach 2000 RPM, ensures effective heat dissipation. In contrast, the upHere H45K6 utilises six heat pipes and a slim 90mm fan that operates within a range of 800 to 2800 RPM. While the upHere is designed for efficient cooling in small form factors, it supports a maximum thermal design power (TDP) of 150W, which may not match the peak cooling capabilities of the Thermalright.
Design and Aesthetics
The Thermalright Frozen Notte features a sleek design with ARGB lighting effects that can be synchronised with motherboard lighting, creating a visually appealing setup. The design includes a mirror-finished copper base and a black aluminium fin cold plate, enhancing both aesthetics and thermal performance. Conversely, the upHere H45K6 prioritises a low-profile design with a height of only 45mm, making it ideal for compact builds. While it lacks the lighting features of the Thermalright, its design ensures compatibility with various components without obstruction.
Installation and Compatibility
In terms of installation and compatibility, the Thermalright Frozen Notte supports a wide range of Intel and AMD sockets, including LGA 1150 to 2066 for Intel and AM2 to AM5 for AMD, ensuring a broad application. Installation is facilitated by a dual platform full metal black buckle. The upHere H45K6 also offers universal compatibility with Intel and AMD sockets, including LGA 1700 and AM4. It guarantees zero RAM obstruction, making it a practical choice for Mini ITX builds. Both products excel in compatibility, but the upHere's low-profile design particularly shines in space-constrained environments.
Noise Levels
Noise levels are an important consideration for many PC enthusiasts. The Thermalright Frozen Notte operates with a maximum noise level of 27.7 DBA due to its efficient PWM fans, which can adjust their speeds based on CPU temperature. This ensures quieter operation during less intensive tasks. The upHere H45K6 features a fan that operates at a maximum of 27 DBA as well, providing a similar quiet experience. However, its smaller fan size may limit airflow at peak performance, although it is designed to maintain low noise levels even under load.
Lifespan and Durability
Durability is critical for any CPU cooler. The Thermalright Frozen Notte is built with high-quality materials, including a copper base and an acrylic top cover, designed for long-term performance. The estimated lifespan of the upHere H45K6’s fan is around 40,000 hours, ensuring longevity in a compact design. While both coolers are engineered for durability, the Thermalright may offer a slight edge with its higher-quality components, especially for users seeking long-term reliability under heavy workloads.
Target Audience
The Thermalright Frozen Notte is ideal for users looking for high-performance cooling and aesthetic features, particularly those who value RGB lighting and enhanced cooling capabilities for demanding applications. It is priced higher, reflecting its advanced features. On the other hand, the upHere H45K6 is perfect for users who require a compact cooling solution that fits in small cases without sacrificing performance. Its lower price tag makes it appealing for budget-conscious consumers or those building compact systems.
Which should you buy?
Choosing between the Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler and the upHere H45K6 Low Profile CPU Cooler ultimately depends on your specific needs. If you value superior cooling performance, aesthetic features, and broad compatibility, the Thermalright is the better choice at C$62.90. However, if you are seeking a more affordable and compact solution for a mini ITX build with reliable performance, the upHere at C$49.99 is an excellent option. Each cooler has its strengths, making them suitable for different user preferences and setups.
