Dimension comparison
Introduction to CPU Coolers
When selecting a CPU cooler, both performance and compatibility are crucial factors. In this comparison, we will look at the Thermalright Phantom Spirit 120 CPU Cooler and the upHere H45K6 Low Profile CPU Cooler. The Thermalright Phantom Spirit is priced at C$47.90, while the upHere H45K6 comes in slightly higher at C$49.99. Each cooler offers unique features geared towards different types of builds and user needs.
Design and Dimensions
The design and dimensions of a cooler can significantly affect its performance and compatibility with various builds. The Thermalright Phantom Spirit stands at 157mm tall, making it compatible with a wide range of chassis models. It features a robust construction with aluminum fins and a finely carved pure copper base. On the other hand, the upHere H45K6 boasts a low-profile design at just 45mm in height, making it an ideal choice for space-constrained Mini ITX cases. This compact design allows for seamless installation without sacrificing cooling performance.
Cooling Performance
Cooling performance is one of the primary functions of a CPU cooler. The Thermalright Phantom Spirit employs a 7x6mm heatpipe configuration with upgraded AGHP technology, offering a long service life of up to 20,000 hours. Its aluminum construction maximizes heat dissipation. Meanwhile, the upHere H45K6 utilizes six Φ6mm heat pipes and dense aluminum fins, ensuring efficient 150W TDP heat dissipation. Both coolers are designed to maintain stable temperatures under sustained workloads, but the upHere's six heat pipes may provide a slight edge in transferring heat away from the CPU.
Noise Levels
Noise levels are an important consideration for users who prefer a quieter computing environment. The Thermalright Phantom Spirit's design incorporates S-FDB bearings, which contribute to a quieter operation but does not specify a noise level in decibels. In contrast, the upHere H45K6 features a slim 90mm PWM fan that operates at a noise level of ≤27 dB(A). This is particularly appealing for silent builds, and the fan's lifespan is rated at 40,000 hours, ensuring durability without performance drop.
Compatibility
Compatibility with various CPU sockets is crucial for ensuring that a cooler can be used across different systems. The Thermalright Phantom Spirit supports a wide array of Intel sockets including LGA1700, LGA1150, and LGA2011, as well as AMD AM4 and AM5. It comes with corresponding mounting plates for different CPU platforms. The upHere H45K6 also offers universal compatibility, supporting Intel LGA1851, LGA1700, and AMD AM5/AM4/AM3 sockets. Its design specifically avoids interference with RAM and motherboard heatsinks, ensuring a hassle-free installation.
Installation Process
The installation process can be a make-or-break factor for many users. The Thermalright Phantom Spirit includes installation instructions and mounting fasteners, making it relatively straightforward to set up. However, it does not specify any particular features that enhance ease of installation. In comparison, the upHere H45K6 boasts a tool-free installation process that can be completed in under five minutes. This user-friendly aspect may appeal to those who prefer a quick and uncomplicated setup.
Aesthetics
Aesthetics can play a significant role in the choice of a CPU cooler, particularly for users who want their build to look appealing. The Thermalright Phantom Spirit features an anodized black frosted top with finely carved details, giving it a sleek and modern appearance. The upHere H45K6 also has a clean, minimalistic design that complements small-form-factor builds. Both coolers offer visual appeal, but the choice will ultimately depend on personal preference and the overall theme of the build.
Which should you buy?
Choosing between the Thermalright Phantom Spirit 120 and the upHere H45K6 ultimately depends on your specific needs and system requirements. If you have a larger chassis and prioritize long-term performance and durability, the Thermalright Phantom Spirit at C$47.90 may be the better option. However, for users with space constraints who need a compact solution without compromising on cooling performance, the upHere H45K6 at C$49.99 would be the optimal choice. Each cooler excels in different areas, making them suitable for varied user scenarios.
