Overview of Noctua NH-U12S Redux and Thermaltake Gravity i2
The Noctua NH-U12S Redux is a high-performance CPU cooler priced at C$62.95, while the Thermaltake Gravity i2 is a budget-friendly option retailing at C$19.86. This stark price difference suggests that the Noctua model is likely aimed at users seeking superior cooling performance and features, while the Thermaltake model caters to those with lower power CPUs or tighter budgets.
The Noctua NH-U12S Redux is a streamlined version of the award-winning NH-U12S, designed for excellent compatibility with various cases and motherboards. In contrast, the Thermaltake Gravity i2 is optimized for low-profile builds and lower power CPUs, showcasing its suitability for compact systems or entry-level setups.
Design and Compatibility
When it comes to design and compatibility, the Noctua NH-U12S Redux shines with its slim 120mm size, allowing it to fit in most tower cases without blocking RAM slots or PCIe slots on ATX and Micro-ATX motherboards. The cooler stands at a height of 158mm, making it a versatile choice for various builds.
On the other hand, the Thermaltake Gravity i2 features a low-profile 92mm design, making it ideal for systems with limited space. It supports various Intel LGA sockets (1200, 1156, 1155, 1150, and 1151), which is impressive for a cooler at this price point. However, its reduced size may limit its cooling efficiency compared to the larger Noctua model.
Cooling Performance
Cooling performance is a critical factor when choosing a CPU cooler. The Noctua NH-U12S Redux is equipped with a quiet NF-P12 redux-1700 120mm fan with PWM control, allowing for automatic speed adjustments based on temperature. This feature ensures that users can experience full cooling performance during intense workloads while maintaining near-silent operation at idle.
In contrast, the Thermaltake Gravity i2 has a 7-bladed low noise fan with an airflow rating of 31.343 CFM and operates at a noise level of 21.3 decibels. While these specifications indicate decent cooling capabilities, they may not match the efficiency and quietness of the Noctua cooler under load.
Installation Process
Both coolers are designed for easy installation, but they cater to different user preferences. The Noctua NH-U12S Redux includes the high-end NT-H1 thermal paste and utilizes the SecuFirm2 mounting system, which is known for its reliability and ease of installation across a wide range of Intel and AMD sockets.
The Thermaltake Gravity i2 also promotes a quick and easy installation process, appealing to users who may not want to spend much time setting up their CPU cooler. While both options are user-friendly, the Noctua provides a more robust mounting system that may be particularly beneficial for users looking for long-term reliability.
Noise Levels
Noise levels are a crucial consideration for many PC builders. The Noctua NH-U12S Redux excels in this domain, with its fan designed to operate quietly, making it an excellent choice for users who prioritize a silent computing experience. Its ability to remain near silent during idle operations contributes to a peaceful environment.
Conversely, the Thermaltake Gravity i2 has a specified noise level of 21.3 decibels, which is relatively low but may still be noticeable, especially in quiet settings. Users who choose the Thermaltake cooler should be aware that while it is designed to minimize noise, it may not achieve the same level of quiet operation as the Noctua.
Target Audience
The target audience for the Noctua NH-U12S Redux includes gamers, content creators, and overclockers who require effective cooling solutions for high-performance CPUs, particularly Intel Core and AMD Ryzen processors. Its higher price point reflects its advanced features and superior cooling capabilities.
In contrast, the Thermaltake Gravity i2 is aimed at users with low to mid-range systems or those building compact PCs. Its affordability makes it an attractive option for budget-conscious consumers or those seeking a basic cooling solution for lower power CPUs.
Warranty and Support
When considering warranty and support, the Noctua NH-U12S Redux offers a level of quality assurance through its established reputation and robust support network. Although specific warranty details aren’t provided, Noctua is known for its customer service and reliability.
The Thermaltake Gravity i2 comes with a 2-year warranty, which is standard for many budget coolers. While this warranty provides some peace of mind, it may not match the level of trust and support that accompanies a Noctua product.
Which should you buy?
In conclusion, your choice between the Noctua NH-U12S Redux and the Thermaltake Gravity i2 should hinge on your specific needs and budget. If you are looking for high performance, superior cooling efficiency, and quiet operation, the Noctua NH-U12S Redux at C$62.95 is a worthwhile investment. However, if you are building a budget system or require a low-profile cooler for low power CPUs, the Thermaltake Gravity i2 at C$19.86 offers excellent value without sacrificing essential features. Ultimately, both coolers have their strengths, catering to different types of users.
