Overview of Thermalright Peerless Assassin 120 CPU Air Cooler

The Thermalright Peerless Assassin 120 CPU Air Cooler is engineered for superior cooling performance, making it a strong contender for those seeking efficient heat dissipation. Priced at C$51.39, this cooler features a dual-tower design that significantly enhances its heat dissipation area to 9600cm². The cooler supports a variety of Intel and AMD sockets, making it versatile for different builds. With a maximum thermal design power (TDP) of 245W, it is well-equipped to handle high-performance CPUs, ensuring stability during intense workloads.

Overview of Thermalright TL-C12CW-S X3 CPU Fan

The Thermalright TL-C12CW-S X3 CPU Fan is an affordable option at C$17.99, ideal for enhancing airflow in cases and CPU coolers. This 120mm fan can reach a maximum speed of 1550 RPM and delivers an impressive 66.17 CFM of airflow, ensuring efficient cooling for various components. Additionally, its ARGB lighting features up to 17 different modes, allowing for customisation and aesthetic appeal. While it is primarily designed as a case fan, it can also complement CPU coolers effectively, improving overall cooling performance.

Cooling Performance Comparison

In terms of cooling performance, the Thermalright Peerless Assassin 120 clearly outshines the TL-C12CW-S X3. With a TDP of 245W, the Peerless Assassin is designed to handle high thermal loads, making it suitable for demanding applications. In contrast, the TL-C12CW-S X3, while capable of 66.17 CFM airflow, is primarily a supplementary fan and not a dedicated CPU cooler. Its maximum speed of 1550 RPM is commendable but does not match the extensive cooling capabilities of the Peerless Assassin. Therefore, if cooling performance is paramount, the Peerless Assassin is the superior choice.

Installation and Compatibility

The Peerless Assassin 120 offers excellent installation flexibility, compatible with a wide range of Intel and AMD sockets, including the latest LGA 1700 and AM5. This adaptability is enhanced by its provision of corresponding mounting plates and fasteners, making installation straightforward for users. In comparison, the TL-C12CW-S X3 is designed primarily as a case fan but can also serve alongside CPU coolers. While both products are easy to install, the Peerless Assassin's compatibility with various socket types and its dedicated design for CPU cooling make it a more robust option for builders.

Noise Levels and Operation

Both the Peerless Assassin 120 and TL-C12CW-S X3 operate quietly, with noise levels capped at 25.6 dB(A). This low noise output is essential for users who prefer a quiet computing environment. The Peerless Assassin, with its dual fans, maintains this noise level while providing exceptional cooling, whereas the TL-C12CW-S X3 manages its noise through quality S-FDB bearings that minimise vibration. While both products are designed for silent operation, the Peerless Assassin’s dual-fan setup offers better heat management without compromising on noise.

Aesthetics and Lighting

The Thermalright TL-C12CW-S X3 excels in aesthetics with its ARGB features, offering up to 17 lighting modes that can be synchronised through the motherboard. This makes it a popular choice for users who want to enhance the visual appeal of their build. On the other hand, the Peerless Assassin 120 also incorporates ARGB lighting but focuses more on performance than aesthetics. While it provides attractive visuals, the primary aim is cooling efficiency. If aesthetic customisation is a key factor for you, the TL-C12CW-S X3 may be the better choice.

Price Consideration

Price is a significant factor in this comparison. The Thermalright Peerless Assassin 120 is priced at C$51.39, reflecting its design as a high-performance CPU cooler. In contrast, the TL-C12CW-S X3, at C$17.99, is an economical fan option, making it accessible for budget-conscious users. While the Peerless Assassin represents a larger investment, it delivers superior cooling performance. Therefore, if your budget allows for it and cooling is your priority, the investment in the Peerless Assassin is justified. However, if you are looking for an affordable enhancement to existing cooling systems, the TL-C12CW-S X3 stands out as a budget-friendly solution.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 CPU Air Cooler and the TL-C12CW-S X3 CPU Fan ultimately depends on your specific needs. If you require a dedicated CPU cooler capable of handling high thermal loads and providing exceptional cooling performance, the Peerless Assassin is the clear winner with its higher TDP and versatile socket compatibility. However, if you are looking for an affordable option to improve airflow and aesthetics in your case, the TL-C12CW-S X3 offers great value with its ARGB features. For those prioritising performance over price, the Peerless Assassin is the way to go, while the TL-C12CW-S X3 is better suited for budget builds or as an additional case fan.
