6 Best Alternatives to the Thermalright Peerless Assassin 120 Mini (2026)

How each alternative compares

Thermalright Burst Assassin 120 EVO Cooler

The Thermalright Burst Assassin 120 EVO Cooler shifts the design to prioritize RAM clearance over raw cooling mass. It keeps the six heat pipes and 120mm fan found in the original but reduces the width to 4.02 inches. This narrower profile helps it fit better alongside tall memory modules. It stands 6.14 inches tall, which is taller than the Mini Black. You get similar socket support for AM5 and LGA 1851. This option suits builders who find the Mini Black too wide for their motherboard layout. It trades some fin surface area for easier installation in crowded RAM slots.

upHere Dual Tower 120mm CPU Cooler

The upHere Dual Tower 120mm CPU Cooler introduces a dual-tower architecture to the list. It retains the six heat pipes and 120mm fan size but changes the physical structure significantly. This design typically offers more fin surface area for heat dissipation. It supports the same modern sockets, including AM5 and LGA 1851. The dual-tower build may increase height, so you must check your case clearance. This cooler is ideal if you need higher thermal performance than the single-tower Mini Black provides. It is a practical choice for users who prioritize cooling capacity over the ultra-compact form factor of the original.

Thermalright Peerless Assassin 120 Black V3

The Thermalright Peerless Assassin 120 Black V3 is a larger version of the Mini Black. It uses the same six heat pipes and 120mm fans but expands the fin stack. The height reaches 6.18 inches, making it taller than the Mini Black. It offers more cooling potential for high-end CPUs. Socket compatibility remains consistent with AM5 and LGA 1851 support. This model is best for builders with larger cases who need maximum cooling performance. It gives up the compact size of the Mini Black for superior thermal headroom. If you have space, this variant delivers more robust cooling without changing the core heat pipe design.

Thermalright AXP120-X67 Black ARGB Low Profile

The Thermalright AXP120-X67 Black ARGB Low Profile is designed for small form factor cases. It keeps the six heat pipes but reduces the height to 2.64 inches. This makes it significantly shorter than the Mini Black. It includes ARGB lighting, which the original does not specify. It still supports AM5 and LGA 1851 sockets. This cooler is the right pick if your case cannot accommodate the 4.92-inch height of the Mini Black. You trade some cooling mass for the ability to fit into tight spaces. It is a specialized solution for ITX builders who need low-profile cooling with modern socket support.

Thermalright Peerless Assassin 120 Dual Fan Cooler

The Thermalright Peerless Assassin 120 Dual Fan Cooler uses a dual-fan setup instead of the single fan in the Mini Black. It maintains the six heat pipes but increases the length to 6.18 inches. This longer design allows for more fins and better airflow. It supports the same sockets, including LGA 1700. This model is suited for users who want higher performance than the Mini Black can offer. It requires more space in your case due to its larger footprint. If you have a mid-tower or full-tower case, this variant provides stronger cooling. It sacrifices the compact size of the Mini Black for enhanced thermal capabilities.

Thermalright 47mm Low-Profile CPU Cooler

The Thermalright 47mm Low-Profile CPU Cooler is built for extreme compactness. It stands only 1.26 inches tall, which is much lower than the Mini Black. It uses six heat pipes and a 120mm fan in a low-profile configuration. This cooler is intended for ITX builds with strict height limits. It supports AM5 and LGA 1851 sockets. You give up significant cooling capacity for the ability to fit in very small cases. This option is best for users who prioritize size over thermal performance. If your case height is under 50mm, this cooler is the only viable choice among these alternatives.
