Performance and Monitoring of the Thermalright Peerless Assassin 140

Dual-Tower Heatsink with Digital Readout

The Peerless Assassin 140 Digital features an imposing dual-tower heatsink and six 6mm copper heat pipes to maximize thermal capacity. Furthermore, the cooler’s standout feature is the integrated Digital Connector, which allows you to monitor the CPU temperature directly on the heatsink cover, giving you instant performance feedback without external software.

Asymmetrical Fan Configuration for Airflow

The cooling system utilizes an asymmetrical dual-fan setup combining a 120mm TL-C12C-X28 V2 fan (82 CFM) and a 140mm TL-D14CB fan (77.8 CFM). In addition, both fans use the fluid dynamic S-FDB bearing for longevity and reduced noise. The staggered arrangement ensures maximum surface coverage of the heatsinks while maintaining excellent compatibility with RAM modules and motherboard VRMs.

⚠️ Important Caution: Component Check

Case Clearance: This cooler has a height of 165mm. You must confirm your PC case supports a cooler of this size, as taller coolers may interfere with the side panel.
Thermal Paste: While Thermalright often includes paste, the inclusion of the MX-6 thermal compound is NOT explicitly listed for this model. Please confirm the inclusion before starting installation.
