120mm ARGB Case Fan With Quiet 5V PWM, 3Pin/4Pin For PC Cooling
Main Description
Explore the 120mm ARGB Case Fan from Erilles — a compact, high-performance cooling solution designed for PC radiators and case airflow. Built to balance strong cooling with striking visuals, this fan helps you keep temperatures in check while adding vibrant ARGB lighting to your build.
With a 9-blade design and a wide speed range (800–1800 RPM, ±10%), it delivers up to 58.36 CFM of airflow without overwhelming noise, thanks to a maximum of 29 dBA. The hydraulic bearing technology reduces friction for longer life, supported by a life rating of up to 100,000 hours and a service life of around 40,000 hours. It supports multiple power interfaces (3-pin/4-pin) and ARGB lighting powered by a 5V header, allowing PWM control and customizable illumination to match your rig’s aesthetics and cooling needs.
Designed for radiator use and versatile motherboard compatibility, this fan is a practical upgrade for users seeking efficient cooling with eye-catching lighting. It pairs a 12V DC rated supply with a 0.25 A current draw and a static pressure of up to 2.07 mmH2O, making it well-suited for radiators and dense case layouts.
