The Thermalright Peerless Assassin 140 SE is a dual tower CPU air cooler featuring six 6mm heatpipes, a C1100 nickel-plated copper base, and a dual fan configuration for strong thermal performance. Including dual PWM fans with one rated up to 1850 RPM delivering high airflow with low noise output, while broad Intel and AMD socket support ensures wide system compatibility.
Features
Peerless Assassin 140 SE
Dual Tower High-Performance Design
The Thermalright Peerless Assassin 140 SE features a dual tower heatsink layout designed to maximise surface area and improve thermal dissipation for high-performance CPUs.
Six Heatpipe Cooling System
Six 6 mm heatpipes paired with a C1100 pure copper nickel-plated base ensure efficient heat transfer from the CPU for sustained cooling performance.
Balanced Dual Fan Configuration
A combination of TL-C12C-X28 V2 and TL-D14CB PWM fans delivers optimised airflow and static pressure, with max speeds rated up to 1500 RPM±10% and 1850 RPM±10%.
Large 140mm Performance Fan
The TL-D14CB 140 mm fan provides up to 77.8 CFM airflow and 2.09 mmH₂O static pressure at 1500 RPM±10%, balancing cooling strength with controlled noise output.
Efficient 120mm PWM Fan Support
The included TL-C12C-X28 V2 120 mm fan delivers up to 88.89 CFM airflow and 2.21 mmH₂O static pressure at 1850 RPM±10%, supporting consistent airflow across the heatsink.
Low Noise Operation
Maintaining a maximum noise level of 29.5 dBA, the air cooler supports quiet system operation under high load conditions.
Wide Platform Compatibility
Support for Intel LGA115X, 1200, 1700, 1851 and AMD AM4, AM5 platforms ensures compatibility across a broad range of systems.
S-FDB Bearing Reliability
S-FDB bearing construction enhances fan durability and stability while maintaining smooth, long-term operation.
