You might be researching thermalright thermalrlght assassin king 120 alternatives to find the right cooling setup for your build. The original Thermalright Assassin King 120 SE features a 148mm height, five 6mm heat pipes, and a 235W TDP rating. It uses a 120mm PWM fan that delivers up to 66.17 CFM of airflow with a noise level of 25.6 dB(A) or lower. These hardware specifications make it a capable single-tower cooler for standard AMD AM4, AM5, and Intel LGA 1700 motherboards.

Still, your computer case may require different dimensions or features. You might need a 47mm low-profile design for an ITX case, a dual-tower layout for extra cooling, ARGB lighting, or a white finish. Other builds may require Intel LGA 1851 mounting compatibility. We chose these 6 alternatives because their specifications overlap with the Assassin King 120, giving you comparable dimensions, heat-pipe counts, and socket support to compare.

Our top pick: Thermalright Assassin King 120 Air Cooler.
