This article covers Thermalright Peerless Assassin 120 デジタル CPU エアクーラー.

Overview

The Thermalright Peerless Assassin 120 Digital (PA120 D W) is a premium air CPU cooler that adds a real-time digital display on top, showing CPU temperature, utilization, and even GPU status. It uses six 6mm heat pipes, a copper base, and dual 120×28mm PWM fans to handle up to 265W TDP. Socket support includes Intel LGA 1851/1700/1200/115X and AMD AM4/AM5, covering both the latest and previous-generation platforms. The combination of strong cooling and an informative top-plate display makes this an appealing choice for builders who value both performance and aesthetics.

Connectivity & Compatibility

The cooler mounts directly to the CPU socket using the included bracket sets for Intel LGA 1851/1700/1200/115X and AMD AM4/AM5. The two PWM fans connect via standard 4-pin headers, enabling automatic speed control from the motherboard. The heatsink measures 125×110×162mm (without fans), so the computer case must have at least 162mm of CPU cooler clearance. Because the fans are 28mm thick, care should be taken with tall RAM modules; low-profile memory is recommended, or the fan clip positions can be adjusted to avoid interference.

Product Info

Launched in late 2024, the Peerless Assassin 120 Digital is priced around ¥27,226 on Japan. It comes with a complete mounting kit for Intel and AMD, fan clips, and a tube of thermal compound. Warranty is typically one year (varies by retailer). In the market, it occupies a mid-high tier position, standing out for its unique digital display at this price point. Few competing air coolers offer a built-in monitoring screen without jumping to a much higher price bracket.

Best Use Cases

This cooler is ideal for showcase builds where the side panel is transparent and the user wants to monitor system vitals without opening software. Overclockers using high-TDP CPUs like the Ryzen 9 7950X or Core i9-13900K will appreciate the 265W capacity. It also suits users who frequently check CPU temperature during stress tests or heavy workloads. If the digital display is unnecessary, the standard Peerless Assassin 120 provides nearly identical cooling performance at a lower cost.
