Chladič/radiátor Thermalright Peerless Assassin 140 120/140 mm biely

The Thermalright Peerless Assassin 140 is a dual-format heatsink designed for compatibility with both 120 mm and 140 mm fan configurations. Engineered for efficient heat dissipation, the cooler pairs a fin-stack radiator with an included fan that operates up to 1500 RPM and uses a fluid dynamic bearing for extended service life and reduced operational noise. The white finish provides a neutral aesthetic that integrates with a wide range of PC builds while the tower-style layout optimizes airflow through the fins for sustained thermal performance.

Advantages

The Peerless Assassin 140 combines a dense aluminium fin array and a high static-pressure fan to deliver effective cooling for mainstream and high-performance processors. Fluid dynamic bearing technology reduces bearing wear and minimizes noise compared with sleeve-bearing designs. The dual-format mounting allows use of either 120 mm or 140 mm fans depending on case clearance and airflow preferences. The compact tower footprint supports memory compatibility on most motherboards while maintaining sufficient fin surface area for heat transfer.

Suitable for

• Air cooling of consumer and gaming desktop CPUs
• Systems where low-noise operation is desired
• Builds requiring a white or neutral cooler aesthetic
• Setups with limited space that still need efficient thermal management

• Maximum fan speed: 1500 RPM
• Bearing type: fluid dynamic bearing
• Material: aluminium fins with a nickel-plated or painted surface finish
• Cooling layout: tower heatsink with direct airflow path through fin stack
• Color: white

How to use

Install the heatsink according to the motherboard and CPU socket compatibility instructions supplied with the product. Apply a thin, even layer of thermal compound to the CPU heatspreader before mounting the base of the heatsink. Secure the cooler using the provided mounting brackets and fasteners, ensuring even pressure across the CPU. Choose between a 120 mm or 140 mm fan installation based on available clearance and desired airflow; connect the fan to a 4-pin PWM header for automatic speed control or to a suitable fan controller. Verify clearance for RAM modules and adjacent components before final tightening.

Recommendations

To maintain consistent cooling performance, check that the fan is free of dust buildup and that airflow paths inside the case are unobstructed. Use PWM control for balanced noise and cooling, and reapply thermal compound if the cooler is removed and reinstalled to preserve thermal conductivity.
