Overview of the Products

The Thermalright PS120SE CPU Air Cooler and the upHere H45K6 Low Profile CPU Cooler are two compelling options for users looking to enhance their CPU cooling solutions. The Thermalright unit is priced at C$44.90, offering a robust cooling solution, while the upHere cooler comes in at a higher price of C$49.99, showcasing a more compact design. Each cooler has unique features that cater to different user needs, making the choice dependent on specific build requirements and preferences.

Design and Build Quality

The Thermalright PS120SE boasts a conventional design with a height of 154mm, crafted from anodized black frosted material and aluminum fins, providing an extensive heat dissipation area. On the other hand, the upHere H45K6 is ultra-compact, measuring only 45mm in height. This sleek profile is ideal for Mini ITX builds, allowing seamless installation without sacrificing cooling performance. Both coolers are built with quality materials; however, the upHere’s low-profile design highlights its versatility in space-constrained environments.

Cooling Performance

When it comes to cooling capabilities, the Thermalright PS120SE supports a thermal design power (TDP) range of 105W to 280W, making it suitable for high-performance CPUs. Its advanced AGHP technology with seven 6mm heat pipes enhances its cooling efficiency. Conversely, the upHere H45K6 features six 6mm heat pipes and efficiently manages a TDP of 150W, ensuring stable temperatures under sustained workloads. While both coolers are effective, the Thermalright can handle a broader range of CPU TDPs, making it a better choice for high-powered processors.

Noise Levels

Noise levels are an essential consideration for users building a quiet PC. The Thermalright PS120SE operates at a maximum noise level of 25.6 dB(A), making it relatively quiet under load. In comparison, the upHere H45K6 features a 90mm PWM fan that runs at a maximum of 27 dB(A) while pushing 35.34 CFM airflow. Both coolers maintain a low noise profile, but the Thermalright has a slight edge with its quieter operation, which may be advantageous for users sensitive to noise.

Compatibility

Compatibility is crucial for ensuring a successful installation. The Thermalright PS120SE supports a wide range of CPU socket types, including Intel LGA1700, 1151, and AMD AM4/AM5, making it versatile for various builds. The upHere H45K6 also boasts universal compatibility, supporting Intel LGA 1851, 1700, and AMD AM4/AM5 sockets. Both coolers guarantee a fit across multiple platforms; however, the Thermalright’s broader compatibility with multiple Intel sockets offers an edge for users with diverse CPU options.

Installation Process

Ease of installation can significantly impact user experience. The Thermalright PS120SE includes all necessary mounting plates and fasteners for different CPU slot platforms, ensuring a straightforward setup. In contrast, the upHere H45K6 promises a tool-free installation that can be completed in under five minutes, making it especially appealing for users who prioritize convenience. While both coolers are designed for easy installation, the upHere’s quick setup process stands out for those who may not want to spend too much time on assembly.

Aesthetic Appeal

Aesthetics can play a considerable role in a PC build, particularly for users showcasing their systems. The Thermalright PS120SE features an anodized black finish that can blend seamlessly with various build themes. The upHere H45K6, while designed with functionality in mind, also provides a sleek look that complements minimalist builds. Ultimately, the choice in aesthetics may come down to personal preference, but both coolers can enhance the visual appeal of any setup.

Which should you buy?

Choosing between the Thermalright PS120SE and the upHere H45K6 depends on your specific needs and build requirements. If you require a cooler that supports a wide range of TDPs and provides quieter operation, the Thermalright PS120SE at C$44.90 is a robust choice. However, if your priority is a compact design for a Mini ITX build with quick installation, the upHere H45K6 at C$49.99 is the way to go. Ultimately, both products excel in their domains, making them worthy contenders in the CPU cooling market.
