CPU cooler Thermalright Peerless Assassin 120 Digital ARGB White with 120mm fan

Thermalright Peerless Assassin 120 Digital ARGB White is a tower-style CPU cooler featuring a single 120mm fan with digital ARGB lighting. It is engineered to move heat away from modern desktop processors through a compact heatsink and a high-airflow fan, offering an option for ATX and microATX systems where space and aesthetics matter. The white finish and addressable RGB lighting provide visual integration with light-themed builds while the cooler's construction focuses on efficient heat transfer and reliable operation.

Advantages

The cooler combines a dense fin stack and multiple heat pipes with a PWM-controlled 120mm fan to deliver steady airflow and effective thermal dissipation for mainstream and mid-range CPUs. Digital ARGB lighting allows synchronized lighting control with compatible motherboards or controllers while the white color complements light-colored cases and components. Its relatively compact footprint makes it compatible with many standard memory and motherboard layouts without excessive interference.

Suitable for

• Gaming desktops with mainstream or mid-range processors
• Content creation workstations with moderate thermal loads
• Compact ATX and microATX builds where a single-tower cooler is preferred
• PC builds seeking coordinated ARGB lighting in a white color scheme

Key specifications

• Cooling design: single-tower heatsink with multiple heat pipes
• Fan size: 120 mm
• Lighting: digital addressable RGB (ARGB)
• Fan control: PWM for variable speed based on temperature
• Finish: white exterior coating
• Compatibility: fits standard ATX and microATX motherboard layouts (check clearance for tall memory modules)

How to use

Install the cooler following the manufacturer’s mounting instructions: secure the mounting bracket to the motherboard, apply a thin, even layer of thermal paste to the CPU heatspreader, align the cooler base and fasten it with the supplied screws. Connect the fan’s 4-pin PWM cable to the CPU fan header and the ARGB cable to a compatible ARGB header or controller to enable lighting control. Verify that memory modules and tall VRM heatsinks do not interfere with the cooler fins or fan before final tightening.

Usage recommendations

For optimal cooling performance, ensure good case airflow by using at least one intake and one exhaust fan and keeping dust filters clean. Use motherboard software or a compatible controller to configure ARGB lighting and set fan curves to balance noise and temperature. Periodically check mounting tightness and clean the fan and heatsink fins to maintain efficiency.
