Know before you buy
The Assassin X 120 Refined SE stands at 148mm tall. It is designed to fit most standard mid-tower cases, but you should verify your case's maximum CPU cooler clearance in your manufacturer's specifications before purchasing.
No, this model features a clean, non-RGB aesthetic. It is an ideal choice if you prefer a minimalist, professional look without the distraction of integrated lighting.
Yes, this cooler is fully compatible with AMD AM5 sockets, as well as AM4 and modern Intel sockets ranging from LGA 1150 to 1700.
The Anti-Gravity Heat Pipe (AGHP) technology ensures consistent thermal performance regardless of whether your PC is oriented vertically or horizontally. It prevents the inverse gravity effect that can sometimes hinder heat dissipation in standard heat pipes.
The fan operates at a noise level of 25.6 dBA. It is engineered to be relatively quiet during standard operation, making it suitable for workstations or home office builds.
The S-FDB (Fluid Dynamic Bearing) is a sealed, maintenance-free design. It is built for longevity, offering a service life of up to 20,000 hours without the need for manual lubrication.
