The Thermalright Phantom Spirit 120 is priced at C$47.90, while the Noctua NM-i17xx-MP78 is significantly cheaper at C$12.95. Both products cater to different needs in the CPU cooling market, with the Thermalright offering a complete cooling solution and the Noctua serving as a mounting upgrade kit for compatible coolers.
Design and Build Quality
The Thermalright Phantom Spirit 120 features a robust design, utilising high-quality materials such as anodized black frosted top and a finely carved pure copper base. This cooler is designed with a height of 157mm and a weight of 0.945kg, ensuring effective heat dissipation. On the other hand, the Noctua NM-i17xx-MP78 is an upgrade kit that comes with a dedicated one-piece backplate, ensuring optimal contact pressure and reliability. While the Thermalright offers a complete cooler, the Noctua emphasises a sturdy and straightforward installation process for users upgrading their existing setups.
Cooling Performance
The Thermalright Phantom Spirit 120 is engineered with advanced AGHP technology, featuring a 7x6mm heatpipe that enhances cooling efficiency and longevity. With an industrial service life rated at up to 20,000 hours, it promises durability and consistent performance. In contrast, the Noctua NM-i17xx-MP78 does not provide cooling performance metrics, as it is not a cooler itself but rather a mounting kit. Therefore, if you are looking for cooling performance, the Thermalright is the clear choice.
Compatibility
The Thermalright Phantom Spirit 120 supports a wide range of CPU sockets including Intel's LGA1700, LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA2011, LGA2066, and AMD's AM4 and AM5. This makes it a versatile option for many builds. Conversely, the Noctua NM-i17xx-MP78 is specifically tailored for Intel’s LGA1851 and LGA1700 sockets. While both products offer compatibility, the Thermalright provides broader options, making it suitable for various systems.
Installation Process
Installing the Thermalright Phantom Spirit 120 requires following specific mounting instructions tailored to different CPU sockets, which are included with the product. Its design allows compatibility with many chassis models. The Noctua NM-i17xx-MP78 is designed for easy installation, featuring a one-piece backplate and straightforward steps for attaching compatible Noctua coolers. While the Noctua kit simplifies the upgrade process, the Thermalright cooler requires more attention to detail during installation due to its comprehensive nature.
Brand Reputation
Thermalright has been in the computer accessory market for over 20 years, gaining a reputation for quality and innovation in CPU cooling solutions. Their focus on research and development has made them a well-respected brand among enthusiasts. Noctua is also renowned for its premium cooling products, particularly in the realm of CPU coolers, with a strong focus on performance and acoustic efficiency. Both brands have established themselves, but Thermalright's long-standing history gives it a slight edge in terms of legacy.
Price Point
The Thermalright Phantom Spirit 120 is priced at C$47.90, which reflects its comprehensive cooling solution status. In contrast, the Noctua NM-i17xx-MP78 is priced at a mere C$12.95, making it an affordable option for those who already own a compatible Noctua cooler but need to upgrade their mounting solution. While the Noctua offers a budget-friendly choice, the Thermalright's higher price is justified by its full-featured cooling capabilities.
User Experience and Feedback
Users of the Thermalright Phantom Spirit 120 often praise its effective cooling performance and aesthetic design, attributing to its ability to keep CPU temperatures in check even under load. The Noctua NM-i17xx-MP78 has received positive feedback regarding its ease of installation and reliability, particularly among those upgrading their existing Noctua coolers.
