Thermalright Launches Upgraded Dual-Tower CPU Coolers Peerless Assassin 120 SE V3 and 140 V3

• June 10, 2026

Thermalright, a recognized name in computer cooling technology, has unveiled two new updates to its Peerless Assassin line of CPU coolers. The latest additions, the Peerless Assassin 120 SE V3 and Peerless Assassin 140 V3, are redesigned dual-tower air coolers aimed at improving thermal performance with upgraded components.

Enhanced Cooling with Dual-Tower Designs

Both models maintain the distinctive dual-tower structure, often referred to as a “D-type” construction, which provides efficient heat dissipation through increased surface area. This arrangement typically features two aluminum fin stacks connected by heat pipes, allowing for high thermal conductivity and improved cooling capacity.

The new Peerless Assassin 120 SE V3 and 140 V3 integrate enhancements over their predecessors in the Peerless Assassin V3 series. Notably, Thermalright has outfitted these coolers with updated fans designed to boost airflow and static pressure, contributing to better cooling efficiency. In addition, the aluminum radiator fins have been refined, which could offer improved heat transfer performance and durability.

While specific technical specifications, such as fan speeds, noise levels, and heat pipe configurations, were not disclosed, the upgrades suggest a focus on achieving an optimal balance between cooling power and quiet operation. This approach is consistent with current market demands where effective thermal management must coexist with low acoustic footprint.

These new models cater to PC enthusiasts and professionals looking to maintain optimal temperatures on modern processors, especially under heavy loads or overclocked conditions. The 120 SE V3 is likely designed to accommodate builds with size or clearance constraints, while the 140 V3 may target users prioritizing maximum cooling through larger fans and heatsink surface.

Although Thermalright has not yet revealed pricing details or availability dates, these additions to the Peerless Assassin lineup underscore the company’s commitment to continuous product refinement. By improving key cooling elements such as fan performance and radiator construction, Thermalright aims to maintain competitiveness in a crowded cooling market.

As high-performance CPUs continue to generate significant heat, effective cooler solutions remain critical for sustaining system stability and extending hardware longevity. The Peerless Assassin 120 SE V3 and 140 V3’s dual-tower designs reaffirm Thermalright’s focus on delivering robust cooling products that meet evolving user needs.
