The Thermalright Assassin X 120 Refined SE RGB V2 CPU Air Cooler is a premium single-tower heatsink cooler that strikes a compelling balance of cooling performance, build quality, and aesthetic flair, made especially for modern Intel and AMD sockets. It uses a heatsink measuring about 120 mm × 46 mm × 148 mm, weighing ~590 g, with four 6-mm copper heat pipes for efficient heat extraction from the CPU. It includes a 120 mm fan (model TL-C12C-L V2) featuring an S-FDB (Silent Fluid Dynamic Bearing), spinning up to ~1550 RPM (±10%), pushing a maximum airflow of ~66.17 CFM and a static pressure of ~1.53 mmH₂O, while capping noise around 25.6 dBA under full load. RGB lighting is integrated (with a 3-pin 5V ARGB connector), though the lighting is fixed and not user-adjustable, so visual flair is there but customization is limited. The fan is powered via a standard 4-pin PWM connector, allowing motherboard control of speed. Compatibility includes Intel sockets 115X / 1200 / 1700 / 1851 and AMD AM4 / AM5. Overall, it’s a strong choice for users wanting high air cool performance, particularly in mid-to-high tier CPUs, who also care about looks — though you should confirm case clearance and ensure good case airflow so it can shine.
