Overview of the Products

In this comparison, we will look at two CPU coolers from Thermalright: the Thermalright Aqua Elite 120 V3 Liquid CPU Cooler and the Thermalright Assassin King 120 SE ARGB CPU Air Cooler. The Aqua Elite is priced at C$41.75, while the Assassin King is more budget-friendly at C$24.59. Both coolers are designed to efficiently dissipate heat, but their technologies and features set them apart in terms of performance and aesthetics.

Cooling Performance

The Thermalright Aqua Elite 120 V3 features a fourth-generation pump head and a 120mm ARGB fan, which together provide excellent cooling capabilities. It boasts an airflow of 66.17 CFM and operates at a noise level of just 25.6 dBA. In contrast, the Thermalright Assassin King 120 SE also claims an impressive airflow of 66.17 CFM, with a similar noise level of 25.6 dBA. Both coolers are capable of handling high thermal design power (TDP), but the Aqua Elite’s water-cooling system generally offers superior performance, particularly under heavy loads.

Design and Aesthetics

Aesthetically, the Thermalright Aqua Elite 120 V3 is equipped with RGB lighting that syncs with your motherboard, providing a visually appealing soft light effect. This feature enhances the overall look of a gaming rig. Conversely, the Thermalright Assassin King 120 SE also includes ARGB lighting, adding a splash of colour to your setup. While both coolers offer impressive lighting effects, the Aqua Elite’s ability to sync with other components gives it an edge in customisation and integration.

Installation Process

Installation is a critical factor when choosing a CPU cooler. The Thermalright Aqua Elite 120 V3 is designed for easy installation, compatible with both AMD (AM4/AM5) and Intel (LGA1150/1151/1155/1156/1200/2011/2066/1700) slots, and comes with all necessary accessories. Users can simply follow the provided instructions for a straightforward setup. The Thermalright Assassin King 120 SE also supports a range of Intel and AMD sockets, making it versatile for different builds. However, it may require slightly more effort for installation due to its air-cooling design.

Noise Levels

Both coolers are designed to operate quietly, with noise levels capped at 25.6 dBA, making them suitable for environments where noise is a concern. However, the Thermalright Aqua Elite 120 V3, with its liquid-cooling design, tends to produce lower noise levels under load compared to air coolers, particularly during gaming sessions or heavy computational tasks. If silent operation is a priority for you, the Aqua Elite may be the more suitable option.

Build Quality and Durability

The Thermalright Aqua Elite 120 V3 is built with high-quality materials, including a black aluminium fin heat sink and protective preparation mesh water pipes, indicating a focus on durability and longevity. Its design aims to reduce evaporation and enhance lifespan. On the other hand, the Thermalright Assassin King 120 SE employs S-FDB bearings and a robust construction of industrial-grade materials, promising a service life of up to 20,000 hours. Both products highlight durability, but the liquid cooling system of the Aqua Elite may offer improved longevity under high-stress conditions.

Price Comparison

Pricing is a significant factor in making a decision. The Thermalright Aqua Elite 120 V3 is priced at C$41.75, which is notably higher than the C$24.59 of the Thermalright Assassin King 120 SE. While the Aqua Elite offers advanced cooling technology and aesthetic features, those on a tighter budget may find the Assassin King to be a more attractive option without compromising much on performance.

Which should you buy?

Choosing between the Thermalright Aqua Elite 120 V3 and the Thermalright Assassin King 120 SE largely depends on your specific needs and budget. If you are looking for superior cooling performance, quieter operation, and aesthetic customisation, the Aqua Elite is the better choice despite its higher price tag. However, if you are seeking a cost-effective solution that still delivers solid performance for general use and gaming, the Assassin King presents a compelling option. Ultimately, your choice should hinge on whether the additional features of the Aqua Elite justify the extra cost for your setup.
