Thermalright TL-C12C-S CPU FanTR-Assassin X 120R SE V2 CPU Air Cooler

Overview of the Thermalright TL-C12C-S CPU Fan

The Thermalright TL-C12C-S CPU Fan is priced at £15.90, offering high-performance cooling capabilities through automatic speed control. This fan features a maximum speed of 1500 RPM, which is ideal for maintaining optimal temperatures in your system. The fan is equipped with a PWM fan cable interface, allowing it to adjust its speed based on the motherboard's temperature, ensuring efficient cooling when needed.

In addition to its cooling prowess, the TL-C12C-S boasts quality S-FDB bearings designed to minimise noise while extending the fan's lifespan. With a noise level of only 25.6 dBA, this fan promises a quiet operation even under load. Furthermore, it has a high airflow rating of 66.17 CFM, making it a strong contender for those seeking effective cooling solutions.

Overview of the TR-Assassin X 120R SE V2 CPU Air Cooler

The TR-Assassin X 120R SE V2 CPU Air Cooler is available for £14.49, making it a slightly more affordable option than the Thermalright fan. This air cooler features a heatsink constructed from a combination of aluminium and copper, providing excellent thermal conductivity. With dimensions of 120mm in length, 71mm in width, and 148mm in height, it is designed to fit comfortably in most ATX cases without obstructing RAM modules.

The cooler is equipped with a high-performance lighting fan that operates at a speed of 1550 RPM, delivering a comparable airflow of 66.17 CFM. Its rated noise level is also capped at 25.6 dBA, ensuring that users do not sacrifice silence for cooling efficiency. The TR-Assassin X 120R SE V2 is compatible with a wide range of Intel and AMD sockets, making it a versatile choice for various builds.

Cooling Performance

In terms of cooling performance, both the Thermalright TL-C12C-S and the TR-Assassin X 120R SE V2 demonstrate impressive specifications. The TL-C12C-S fan achieves a maximum speed of 1500 RPM, providing an airflow of 66.17 CFM and a static pressure of 1.53mm H2O. This makes it particularly effective at dissipating heat from the CPU and case.

On the other hand, the TR-Assassin X 120R SE V2 operates at a slightly higher speed of 1550 RPM, but also maintains an airflow of 66.17 CFM, which suggests that it can match the Thermalright fan in terms of cooling capability. Both models have a noise level of 25.6 dBA, making them equally suitable for quiet builds. However, the choice may come down to whether you prefer a dedicated fan or an integrated air cooler design.

Design and Aesthetics

When it comes to design, the Thermalright TL-C12C-S features a sleek look with high-brightness LED lighting that can create a variety of effects, including up to 17 different modes. This allows users to customise the lighting to match their system's aesthetics, enhancing the overall visual appeal.

Conversely, the TR-Assassin X 120R SE V2 also offers a stylish appearance with its static RGB lighting. While it may not provide the extensive customisation options that the TL-C12C-S does, its design is still modern and fits well with contemporary builds. The aluminium and copper heatsink materials not only aid in cooling but also contribute to a solid, premium look that many users appreciate.

Installation and Compatibility

The Thermalright TL-C12C-S is designed for versatility, suitable for use as either a case fan or a CPU cooler. Its 55cm PWM cable ensures easy connection and integration into existing setups. However, users should ensure that their cases can accommodate the 120mm fan size.

In contrast, the TR-Assassin X 120R SE V2 features a thoughtful design that includes a total height of just 148mm, allowing it to fit in most ATX cases without obstructing RAM modules. Installation is made simpler with the SS2 install system and a metal pressure plate for enhanced CPU contact. It supports a wide range of Intel and AMD sockets, making it a highly compatible choice for various builds.

Noise Levels

Both the Thermalright TL-C12C-S and the TR-Assassin X 120R SE V2 operate quietly, with a maximum noise level of 25.6 dBA. This is a crucial factor for users who prefer a silent computing experience, particularly for gaming or content creation. The quality bearings used in both models help minimise operational noise, ensuring that neither of these coolers becomes a distraction during usage.

While both products achieve the same noise level, the design and intended use may influence which is quieter in practice. The TL-C12C-S functions as a fan that may be used in multiple configurations, while the TR-Assassin X 120R SE V2 is an all-in-one solution that integrates noise-reducing features within its heatsink design.

Price and Value

When comparing the price points, the Thermalright TL-C12C-S is priced at £15.90, while the TR-Assassin X 120R SE V2 is slightly cheaper at £14.49. While the price difference may seem minimal, it could influence decision-making for budget-conscious buyers.

Both products offer excellent value for their cooling capabilities, but depending on your specific needs—whether you prioritise aesthetics, compatibility, or multifunctionality—you might find one better suited to your requirements than the other.

Which should you buy?

Deciding between the Thermalright TL-C12C-S and the TR-Assassin X 120R SE V2 ultimately depends on your specific needs and preferences. If you are looking for a high-performance fan with extensive customisation options for lighting and a simpler installation process, the Thermalright TL-C12C-S could be the better choice. However, if you prefer an all-in-one CPU cooler that provides excellent performance while being slightly more affordable, the TR-Assassin X 120R SE V2 is a strong contender. Both products deliver exceptional cooling capabilities, making them worthy investments for any PC build.
