Dimension comparison
Overview
When it comes to cooling solutions for your CPU, both the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler and the Thermalright TL-S12RW X3 CPU Fan offer distinct advantages. The Peerless Assassin is priced at C$52.62 and features advanced cooling technology, while the TL-S12RW X3 is a budget-friendly option at C$19.90, designed for versatility. This comparison explores their features, performance, and suitability for different setups.
Design and Aesthetics
The design of the Thermalright Peerless Assassin 120 is striking, featuring dual towers and dual fans, enhanced by adjustable ARGB lighting that can sync with your motherboard's software. This cooler measures 125x138x162mm, presenting a robust appearance that complements high-performance builds. In contrast, the TL-S12RW X3 sports a minimalist pure white design with slim ARGB lines, which also enhances its aesthetic appeal. Its size of 120x120x25mm makes it a more compact option, easily fitting into various cases. This difference in design philosophy caters to users looking for either a statement cooler or a simple yet effective fan.
Cooling Performance
The Thermalright Peerless Assassin excels in cooling performance, thanks to its dual fans operating at a speed of 1850 RPM and generating an impressive air volume of 88.89 CFM. This setup allows for efficient heat dissipation, making it suitable for high-performance CPUs under heavy load. On the other hand, the TL-S12RW X3 delivers a solid performance with a fan speed of 1500 RPM and an air flow of 47.6 CFM. While it may not match the sheer cooling power of the Peerless Assassin, it is still effective for general use and can serve as a supplementary fan for additional cooling.
Noise Levels
Noise levels are a crucial factor for many PC builders, and both products are designed to operate quietly. The Peerless Assassin boasts an operating noise level of ≤25.6 dBA, which is quite reasonable given its performance capabilities. Meanwhile, the TL-S12RW X3 is slightly quieter with a maximum noise level of ≤23.2 dBA, making it an excellent choice for users who prioritise a silent operation. While the difference is marginal, those sensitive to noise may prefer the TL-S12RW X3 for its quieter performance.
Installation and Compatibility
Both the Thermalright Peerless Assassin and TL-S12RW X3 are designed with user-friendly installation in mind. The Peerless Assassin comes equipped with SS2 clips that offer compatibility with a wide range of CPU sockets, including AMD AM4/AM5 and Intel LGA1700/1200 series. This versatility ensures that it can fit into various systems without hassle. The TL-S12RW X3, while primarily a fan, can also be used in conjunction with CPU coolers to enhance overall cooling. Its 4-pin PWM connector simplifies installation, making it accessible for users of all experience levels.
Lifespan and Reliability
Reliability in cooling solutions is paramount, and both products are built to last. The Peerless Assassin features S-FDB bearings in its fans, which are designed for longevity and optimal performance over time. This is complemented by its robust build quality, ensuring it can handle high thermal loads effectively. Similarly, the TL-S12RW X3 utilises S-FDB V2 bearings, addressing issues related to vibration and ensuring a longer lifespan. Both options offer dependable performance, but the Peerless Assassin may have a slight edge due to its higher-end components.
Value for Money
In terms of value, the Thermalright TL-S12RW X3 stands out as a budget-friendly option at C$19.90. It offers decent cooling performance and aesthetic appeal, making it suitable for users looking for an economical solution. The Peerless Assassin, priced at C$52.62, is a more expensive option but provides superior cooling performance and features, justifying the higher price point for gamers and professionals who demand more from their cooling solution. Ultimately, the choice depends on your budget and cooling requirements.
Use Cases
The Thermalright Peerless Assassin is ideal for high-performance gaming setups and demanding applications, where maintaining lower temperatures is crucial for optimal performance. Its dual-fan configuration and high cooling capacity make it suitable for overclocking scenarios. Conversely, the TL-S12RW X3 is perfect for users looking for a versatile fan that can serve both as a case fan and an auxiliary cooler for CPU heatsinks. Its lower price and sufficient airflow make it an excellent choice for budget builds or as an upgrade for existing systems.
Which should you buy?
