This article covers Thermalright Peerless Assassin 140 SE ARGB CPUエアクーラー 6本のヒートパイプ付き 厚さ28mm パフォーマンスグレードファン 158mm 高CPU冷却 AM5.

Overview

The Thermalright Peerless Assassin 140 SE ARGB is a dual-tower CPU air cooler that delivers flagship-level cooling performance at a remarkably affordable price. With a total height of 158mm, it fits most mid-tower cases while handling CPUs with up to 275W of thermal load. Six 6mm heat pipes with AGHP (Anti-Gravity Heat Pipe) technology ensure consistent performance regardless of orientation, making it a versatile choice for various builds.

Connectivity & Compatibility

This cooler supports Intel sockets LGA1851/1700/1200/115x and AMD AM4/AM5, covering virtually all modern platforms. Note that on AMD motherboards, you must reuse the stock backplate — the cooler does not include its own backplate. The included fans use 4-pin PWM for speed control and 5V 3-pin ARGB headers for lighting, allowing synchronization with motherboard RGB software. The 158mm height requires checking your case’s maximum CPU cooler clearance before purchase.

Product Info

The Peerless Assassin 140 SE ARGB was released around 2025 and sits in the mid-to-high-end tier of air coolers, with a rated TDP of 275W. It can comfortably cool flagship CPUs like the Core i9-13900K or Ryzen 9 7950X under full load. Pricing on Japan is approximately ¥9,370, an exceptional value for this performance class. The package includes a PWM splitter cable, universal mounting kit (SS2), and installation manual. Warranty is typically 2–3 years, subject to manufacturer terms.

Best Use Cases

High-end CPU cooling on a budget: If you run a Core i9 or Ryzen 9 and want to avoid the cost and complexity of liquid cooling, this cooler offers equivalent performance at a fraction of the price. However, the dual-fan setup can be audible under heavy load, so noise-sensitive users may prefer a quieter alternative. Cost-conscious PC builders: For under $65 (or ¥10,000), this cooler rivals many premium air coolers costing twice as much. Ideal for users who prioritize performance per dollar. But be aware that its large size may cause clearance issues with tall RAM modules or narrow cases. * ARGB enthusiasts: Both fans feature addressable RGB lighting that can be customized via motherboard software. Builds with tempered glass side panels will showcase the lighting effect nicely. Just ensure your case has enough width — the cooler’s 160mm depth may touch the side panel in some slim cases.
