The sleek black design enhances any build while providing efficient cooling for processors.

## Long description

The Thermalright Peerless Assassin 120 Digital ARGB 12 cm Black is a compact CPU heatsink designed for desktop processors. It combines a 120 mm fan with a Fluid Dynamic Bearing for reduced noise and longer service life. The cooler's black finish and ARGB-capable fan suit modern system aesthetics while delivering directed airflow to help maintain processor temperatures within expected ranges. Dimensions are 138 mm (width) x 125 mm (depth) x 162 mm (height), making it suitable for many mid-tower and compact cases that accommodate tower-style air coolers.
Advantages
The Peerless Assassin 120 offers a balance of size and performance with a 120 mm fan that provides a minimum air pressure of 2.21 mmH2O, enabling effective heat transfer from the heatsink fins. The Fluid Dynamic Bearing reduces operational noise and increases fan longevity. The ARGB lighting allows integration with motherboard or controller lighting ecosystems for coordinated system visuals. The black finish supports neutral builds while concealing dust and wear.
Suitable for
 Mainstream desktop builds where a compact tower cooler is required
 Systems using supported CPU sockets: Socket AM5, AM4, LGA 1700, LGA 1200, LGA 1156, LGA 1155, LGA 1151, LGA 1150
 Users who want ARGB lighting compatible with standard controllers or motherboard headers
 Quiet PC builds that benefit from Fluid Dynamic Bearing fan technology
When it may not be suitable
This heatsink is a single-tower cooler with a 120 mm fan and may not match the thermal capacity of larger dual-tower air coolers or high-performance liquid cooling solutions for extreme overclocking. Its size, while compact for a tower cooler, still requires case clearance that may not be available in very small form-factor enclosures.
Key specifications
 Type: Heatsink/Radiator (air cooler)
 Fan diameter: 120 mm
 Bearing type: Fluid Dynamic Bearing (fan)
 Minimum air pressure: 2.21 mmH2O
 Product colour: Black
 Dimensions (W x D x H): 138 mm x 125 mm x 162 mm
 Supported processor sockets: Socket AM5, Socket AM4, LGA 1700, LGA 1200, LGA 1156, LGA 1155, LGA 1151, LGA 1150
How to use
Install the cooler following the manufacturer's mounting instructions and use the compatible bracket for your processor socket. Apply a thin, even layer of thermal compound to the CPU heatspreader before seating the heatsink to ensure proper thermal transfer. Connect the fan's power and ARGB cables to the appropriate motherboard headers or controller: the fan power to a 4-pin PWM header for speed control, and the ARGB connector to a compatible 3- or 4-pin RGB header depending on the cooler's connector type. Ensure the cooler orientation does not obstruct memory modules or other motherboard components and that case airflow supports intake and exhaust around the cooler.
What to consider before purchase
 Check case CPU cooler clearance for a height of 162 mm
 Verify motherboard has the required fan and ARGB headers, or plan for an external controller
 Confirm compatibility with your CPU socket from the supported list
 Consider whether a single 120 mm tower cooler meets your cooling needs for overclocking scenarios
Usage recommendations
For optimal performance, pair the Peerless Assassin 120 with balanced case airflow: front intake and rear/top exhaust. Periodic dust cleaning of the fins and fan will maintain cooling efficiency. Use motherboard fan curves or PWM control to adjust fan speed according to temperature for a balance between noise and cooling.
