This article covers Thermalright Peerless Assassin 120 SE ホワイト V2 CPU エアクーラー.

Overview

The Thermalright Peerless Assassin 120 SE White V2 (PA120 SE W V2) is a high-performance dual-fan CPU air cooler featuring six 6mm heat pipes with AGHP GEN 5.0 technology. Its white-coated aluminum fin stack and copper base handle up to 265W TDP, making it suitable for top-tier processors. The 120mm dual fans deliver 88.89 CFM at 1850 RPM while keeping noise under 29.5 dBA. This cooler is designed for users who want air-cooling reliability with performance rivaling entry-level liquid coolers. The AGHP (Anti-Gravity Heat Pipe) technology ensures consistent thermal transfer regardless of orientation, so it works well in both vertical and horizontal mounts. Included mounting kits support Intel LGA 1851/1700/1200/115X and AMD AM4/AM5 sockets.

Connectivity & Compatibility

Installation requires a 4-pin PWM CPU fan header on the motherboard. The dual-fan setup can run directly from a single header (Y-splitter included) or be connected to separate headers for individual control. Compatible with all standard ATX and Micro-ATX motherboards that support the listed sockets. Physical clearance: the cooler is 155mm tall, 125mm wide, and 135mm deep. Ensure your case has at least 155mm of CPU cooler clearance. For RAM clearance, the 120mm fan overhangs the first memory slot slightly; use standard-height RAM or move the fan upward slightly (if case clearance allows).

Product Info

Released around late 2024, the Peerless Assassin 120 SE White V2 is priced at approximately ¥9,019 on Japan – an outstanding value for its cooling capacity. The cooler comes with Intel and AMD mounting hardware, a tube of thermal paste, and a user manual. Warranty is typically 2-3 years from Thermalright. Market positioning: mid-high tier air cooler that offers near high-end air cooling performance at an affordable price. It fills the gap between budget 120mm tower coolers and expensive dual-tower flagship models. Ideal for builders who want strong cooling without the cost and pump reliability concerns of AIO liquid coolers.

Best Use Cases

High-end gaming and workstations: Cool processors like Core i7-14700K or Ryzen 9 7950X effectively in sustained loads. Enough headroom for moderate overclocking on most CPUs. Recommended for users who need stable, maintenance-free cooling for long sessions. White-themed PC builds: The all-white design blends perfectly with white components and cases. Whether for a clean aesthetic or a themed setup, this cooler adds visual consistency without sacrificing performance. * Silence-oriented builds: At 29.5 dBA maximum noise, it's barely audible even under load. Ideal for home offices, media centers, or any environment where low noise is a priority.
