This article covers Thermalright Peerless Assassin 120 SE Extrem CPUエアクーラー 6本のヒートパイプ付き デュアルPWMファン AGHPヒートパイプテクノロジー 154mm高冷却 AM5.

Overview

The Thermalright Peerless Assassin 120 SE Extrem is a dual-tower CPU air cooler designed for cost-conscious builders. With six AGHP heat pipes and two 120mm PWM fans, it can handle CPUs with TDPs up to roughly 200W. The cooler's 154mm height makes it compatible with most mid-tower and full-tower cases. It supports Intel LGA1851, 1700, 115x, 1200 and AMD AM4/AM5 sockets, making it a future-proof choice for current-generation platforms.

Connectivity & Compatibility

Socket support: Intel LGA1851/1700/1150/1151/1155/1156/1200, AMD AM4/AM5 (uses motherboard backplate for AMD). Cooler height is 154mm, fitting most cases with a CPU cooler clearance of 155mm or more. Always check your case specs before purchase. The heatsink has a memory cutout design to avoid interference with standard-height RAM. For tall memory modules, the fan can be moved upwards slightly to gain clearance. The fan headers are standard 4-pin PWM, compatible with all modern motherboards.

Product Info

Release: Current model, launched around 2025. Price: Approximately ¥8,421 ( Japan). Warranty: Manufacturer's standard warranty (typically 1-2 years; confirm with retailer). Included: 2x 120mm PWM fans, mounting kits for Intel/AMD, fan clips, thermal grease, manual. * Market position: Entry-to-mid-range air cooler. It offers dual-tower performance at a price point that competes with single-tower models, making it an outstanding value for builders looking for quiet, effective cooling without needing liquid cooling.

Best Use Cases

Budget-conscious builders: Ideal for CPUs like Ryzen 5/7 and Core i5/i7 non-K variants (TDP 65-150W). The cooler provides ample thermal headroom for daily use and light overclocking at a fraction of the cost of AIOs. Silence seekers: The dual PWM fans operate quietly up to 29.6dBA. At idle, the cooler is nearly inaudible. Users who work overnight or need a quiet environment will appreciate the low noise profile. Airflow enthusiasts: Dual-tower coolers exhaust heat directly toward the rear exhaust fan, improving overall case airflow. The cooler also helps cool VRM and memory areas indirectly. What to avoid: High-end CPUs with extreme power draw (e.g., Core i9-13900K under full load) may overwhelm the cooler. Also, very compact cases with less than 155mm clearance will not fit; consider a low-profile cooler or liquid cooling instead.
