Dimension comparison
Overview of the Products
In this comparison, we pit the Corsair iCUE LINK QX120 RGB fans against the Thermalright Peerless Assassin 120 SE ARGB CPU air cooler. The Corsair fans are priced at £105.15, while the Thermalright cooler offers a more budget-friendly option at £28.79. Understanding the distinct features and purposes of each product will help you determine which is better suited for your cooling needs.
Design and Aesthetics
The Corsair iCUE LINK QX120 RGB fans boast a modern design with 34 RGB LEDs spread across two distinct light zones, allowing for vibrant lighting modes. This makes them ideal for gamers and PC builders looking to enhance their system’s visual appeal. On the other hand, the Thermalright Peerless Assassin 120 SE features a more understated yet stylish design with ARGB lighting effects. While both products incorporate RGB elements, the Corsair fans offer a more elaborate lighting experience that can be tailored through the iCUE software.
Cooling Performance
Cooling performance is crucial in any build, and both products deliver effectively in their respective categories. The Corsair fans can achieve PWM-controlled speeds ranging from 480 RPM to 2,400 RPM, producing a maximum airflow of 63.1 CFM and 3.8 mm-H2O of static pressure. This versatility allows users to adjust cooling based on system demands. Conversely, the Thermalright cooler utilises two PWM fans, with a maximum airflow of 66.17 CFM at 1,500 RPM. This marginally higher airflow makes it slightly more effective for CPU cooling, particularly during intense workloads.
Noise Levels
Noise levels are a significant consideration for many PC users, especially in quiet environments. The Corsair iCUE LINK QX120 fans feature a Zero RPM mode, which eliminates fan noise under low loads, making them exceptionally quiet when not under pressure. Meanwhile, the Thermalright cooler claims a noise level of ≤25.6 dB(A). While the fan's noise is relatively low, it may not match the silent operation of the Corsair fans when they are in Zero RPM mode, providing a distinct advantage for those prioritising a noise-free experience.
Installation and Compatibility
Installation ease is essential for both novice and experienced builders. The Corsair fans come with an iCUE LINK System Hub and bridge connectors, allowing users to connect multiple fans with a single cable, reducing clutter. In contrast, the Thermalright cooler is compatible with a range of sockets including Intel 115X/1200/1700/17XX/1851 and AMD AM4/AM5, which enhances its versatility in different builds. The presence of mounting plates ensures that the cooler can be easily installed across various platforms, making it a flexible choice for users.
Cooling Technology
The Corsair iCUE LINK QX120 fans utilise a Magnetic Dome bearing, which reduces friction and enhances performance at low speeds. This technology ensures longevity and reliability under varying loads. The Thermalright Peerless Assassin, however, employs AGHP (Advanced Gravity Heat Pipe) technology, which addresses the inverse gravity effect in both vertical and horizontal orientations. This innovation improves the cooler's effectiveness in dissipating heat, making it particularly advantageous for high-performance CPUs.
Value for Money
When it comes to value for money, the Thermalright cooler is significantly more affordable at £28.79 compared to the Corsair fans at £105.15. This price difference makes the Thermalright a compelling option for users on a budget who still desire effective cooling performance. However, the Corsair fans offer advanced features such as stunning RGB lighting and enhanced control through the iCUE software, which may justify the higher price for those who prioritise aesthetics and customisation in their builds.
User Experience and Support
User experience can heavily influence product satisfaction. The Corsair iCUE LINK QX120 fans benefit from robust software support, allowing users to customise their lighting and fan speeds for an optimised experience. Corsair is known for its customer service, providing users with assistance when needed. On the other hand, Thermalright, with over 20 years in the industry, has a solid reputation for producing reliable products and offers a straightforward installation process, but may not have as extensive software support compared to Corsair.
Which should you buy?
In conclusion, the choice between the Corsair iCUE LINK QX120 RGB fans and the Thermalright Peerless Assassin 120 SE ARGB CPU cooler largely depends on your specific needs and budget. If you are looking for aesthetically pleasing fans with advanced features and superior silent operation, the Corsair iCUE LINK QX120 is worth the investment. However, if you need a cost-effective, efficient CPU cooler with solid performance, the Thermalright Peerless Assassin 120 SE is an excellent choice that won't break the bank.
