The Thermalright Peerless Assassin 140 Digital CPU Air Cooler Black [Peerless Assassin 140 Digital Black] is a high-performance dual-tower cooling solution designed to handle the intense thermal demands of modern multi-core processors. This flagship-tier air cooler combines a refined matte black aesthetic with a high-density fin array, offering a sophisticated look that fits perfectly into professional and enthusiast builds alike.
This digital edition features an integrated real-time temperature display on the top cover, allowing users to monitor CPU thermals at a glance without needing to open software overlays. By utilizing six 6mm sintered copper heat pipes and a combination of 140mm and 120mm TL-series fans, it maximizes airflow and static pressure while maintaining a balanced acoustic profile for quiet operation.
Real-Time Digital Monitoring: Top-mounted display provides accurate CPU temperature readings and high-temperature alerts via a simple internal header connection.
Dual-Tower Heat Dissipation: Dual-tower heatsink design significantly increases surface area for heat exchange, supporting high TDP processors.
High-Performance TL Fans: Equipped with one TL-D14 (140mm) and one TL-C12 (120mm) PWM fan featuring S-FDB bearings for long-lasting, quiet performance.
AGHP Generation 4 Heat Pipes: Six 6mm heat pipes utilize Anti-Gravity Heat Pipe technology to ensure optimal performance regardless of the cooler’s mounting orientation.
Optimized RAM Clearance: The asymmetric fin design and secondary fan placement are engineered to provide maximum compatibility with high-profile memory modules.
Premium Black Finish: Fully coated in a specialized black thermal paint that enhances heat radiation while providing a clean, stealthy appearance.
In-Store Advice: We can verify if your specific PC case has the necessary 158mm height clearance to accommodate this dual-tower cooler and ensure your RAM height won’t interfere with the fan positioning.
Local Support: If you’re building a new system in Charmhaven, our technicians can assist with the application of high-grade thermal paste and the configuration of the digital display headers in your BIOS.
