Overview
The Thermalright Peerless Assassin 120 White ARGB is a dual-tower CPU air cooler that has earned a strong reputation among PC builders for its impressive price-to-performance ratio. With six 6mm nickel-plated copper heat pipes, dual 120mm PWM fans, and an all-white finish, it's a visually cohesive choice for white-themed builds. Cooling performance is often compared favorably to entry-level 240mm AIO liquid coolers, making it a compelling alternative for users who prefer air cooling's reliability and silence. Standing 157mm tall, it fits in most mid-tower cases while being only 135mm wide and 125mm deep. The included mounting kit supports Intel LGA115x/1200/1700/2066 and AMD AM4/AM5 sockets, covering virtually all current desktop platforms. The package also includes a backplate and thermal compound, so you can start building right away.
Connectivity & Compatibility
The cooler supports Intel LGA1150/1151/1155/1156/1200/1700/2066 and AMD AM4/AM5. LGA1700 compatibility means it works with Alder Lake, Raptor Lake, and newer Intel Core chips. AMD users with Ryzen 7000 or 8000 series on AM5 are also fully covered. For ARGB lighting, a 5V 3-pin header on the motherboard is required. If you don't use RGB, the fans still function as standard PWM fans. The design allows one fan to be mounted slightly higher to clear tall RAM modules, but we recommend checking clearance for memory with very tall heat spreaders, especially if installed in the first DIMM slot.
Product Info
Released around 2021, the Peerless Assassin 120 White ARGB remains widely available through major retailers including . Pricing hovers around ¥7,700 in Japan, which is remarkably affordable for a cooler of this caliber. Its market position is solidly mid-range to upper-mid-range — capable of handling CPUs with 200W+ TDP while costing far less than many competitors with similar cooling capacity. The warranty is generally 2 years from Thermalright. The package includes Intel and AMD mounting hardware, a backplate, thermal paste, and (in some batches) a basic ARGB controller. The white variant extends the white finish to the fans and heat pipe caps, ensuring a clean look in light-colored builds.
Best Use Cases
The Peerless Assassin 120 is ideal for users who want to cool a mid-to-high-end CPU like a Ryzen 7 7800X3D or Core i7-13700K without the noise and potential failure points of a liquid cooler. It's a perfect choice for those who prioritize long-term reliability and quiet operation over the aesthetics of an AIO pump. It's also a top pick for white-themed PC builds. The all-white body and fans blend seamlessly with white cases, motherboards, and cables, allowing you to maintain a consistent color scheme without sacrificing thermal performance. Finally, budget-conscious builders will appreciate the exceptional value: you get cooling comparable to many dual-tower coolers at a price that undercuts most by a significant margin.
