THERMALRIGHT Peerless Assassin 140 Digital Black CPU Cooler

The Peerless Assassin 140 Digital Black stands apart from typical air coolers by pairing a dual-tower heatsink with a real-time digital display, giving you live CPU temperature, load, and fan speed readouts right on the cooler. This is more than a cooling solution—it’s a performance monitor built into your build.

Highlights

• Dual-tower design with six 6mm heatpipes and nickel-plated copper base for rapid heat transfer
• Two Thermalright TL-D14B 140mm PWM fans deliver up to 84.5 CFM airflow at just 21 dBA
• Integrated digital display shows CPU temperature, load percentage, and fan speed via internal USB 2.0 header
• Broad compatibility with Intel LGA1700/1200/115X and AMD AM5/AM4 sockets
• Includes Thermalright TF7 thermal paste for optimal thermal interface

In daily use

Whether you’re pushing a high-core-count CPU in rendering or gaming for hours, the Peerless Assassin 140 Digital keeps temperatures in check without acoustic penalty. The S-FDB bearing fans spin from 300 to 1800 RPM, adjusting automatically via PWM to match load. The digital display eliminates guesswork—glance at your case to see real-time stats, no software required.
