Jonsbo FR-505 120mm ARGB Infinity Mirror fan

The Jonsbo FR-505 is a 120 mm chassis fan with 5V ARGB lighting and an Infinity Mirror effect. Its 25 mm thickness and standard 120 mm footprint fit most cases and radiators, while the mirrored ARGB ring produces a pronounced visual depth around the blades. It’s aimed at builders who want striking ARGB visuals without changing standard fan sizing.

The FR-505 supports PWM speed control and is rated for roughly 800–1800 ±10% RPM, offering a balance of airflow and moderate noise. Lighting uses a 3‑pin 5V ARGB header and the fan motor uses a 4‑pin PWM (12V) connector, so you can sync effects with a motherboard or control speeds via BIOS/software.
