Overview

The Thermalright Peerless Assassin 140 Digital Black is a dual-tower CPU air cooler that stands out with its magnetic ARGB digital display on the top cover. This display shows real-time CPU and GPU temperature and usage data, making it a great choice for builders who want both strong cooling and a visual monitoring tool without needing a separate screen. The cooler uses six 6mm heat pipes with AGHP 5.0 anti-gravity technology, a precision reflow-soldered copper base, and a dual-fan setup (120mm + 140mm) to handle high-TDP processors from both Intel and AMD platforms. With a total height of 165mm and a weight of 1.89kg, it's a substantial cooler that fits most mid-tower cases. The fans use S-FDB bearings for long life and PWM control for automatic speed adjustment. The digital display connects via a 9-pin USB 2.0 internal header and can be configured with the TRCC software to change color based on temperature thresholds.

Connectivity & Compatibility

The cooler supports Intel LGA1851/1700/1200/115x/2011/2066 and AMD AM4/AM5 sockets. For AMD platforms, you must use the motherboard's original backplate — the cooler does not include one. Memory clearance is rated for modules up to 44mm in height, so most standard DDR5 and DDR4 kits will fit without issue. Fan control uses standard 4-pin PWM headers, and the included Y-splitter cable lets you run both fans from a single motherboard header. The digital display requires a 9-pin USB 2.0 internal header on the motherboard for power and data. If your motherboard lacks a spare USB 2.0 header, you may need a USB 2.0 hub or splitter.

Best Use Cases

Enthusiasts who want real-time monitoring without software: The magnetic digital display shows CPU and GPU temperature and usage at a glance, which is especially useful if you run a glass-side-panel case or keep your PC on your desk. No need to alt-tab or run an overlay. Budget-conscious builders aiming for high-end cooling: At around ¥11,293, this cooler undercuts premium air coolers from Noctua and be quiet! by a significant margin while still delivering strong thermal performance for CPUs like the Ryzen 9 7950X or Core i9-14900K under normal workloads. Users who want a clean, customizable aesthetic: The magnetic ARGB digital display and black finish fit well in modern builds. The TRCC software lets you adjust the display color, and the fans have soft corner pads to reduce vibration noise. Not ideal for: Small-form-factor (SFF) cases due to the 165mm height, or users who need a backplate for AMD motherboards (the cooler relies on the stock backplate). Also, if your motherboard lacks a spare 9-pin USB 2.0 header, you'll need an adapter.
