Key Features

Made for all-black and non-RGB PC builds, ASSASSIN X120-A DARK uses a dark heatsink, black fan, and black top cover to hide exposed heat-pipe ends, giving the cooler a cleaner look through side-window cases
Four 6mm heat pipes with Thermalright AGHP design help pull heat away from the CPU surface, making this single tower CPU air cooler a solid upgrade from basic stock cooling for everyday work, gaming, and multitasking
The TL-N12-R9 V2 120mm PWM fan runs up to 2400RPM and delivers 85.35CFM airflow with 2.95mmH2O static pressure, giving the cooler extra airflow headroom when the system is under heavier load
A continuous blade tip ring helps guide airflow through the heatsink and supports fan stability at higher speeds. 4Pin PWM control lets the fan slow down during light use and ramp up when more cooling is needed
Pressure-style mounting hardware helps keep the heatsink firmly seated on the CPU. The 151mm cooler height fits many mainstream tower cases and supports AMD AM5/AM4 and Intel LGA1851/1700/1200/115X platforms. TF4 thermal paste is included
