Purpose and benefits Compact, USB-powered cooling for small electronics and tight spaces. Reduces operating temperatures to improve reliability and prevent thermal throttling or shutdowns during prolonged use. Delivers effective cooling with minimal noise so you can maintain performance without adding audible distraction. Key features that matter Size and power: 70 x 25 mm frame, USB 5V powered with a 93 cm USB cable for flexible placement and easy connection. Performance: Up to 28 CFM airflow at a stable 2300 RPM for steady cooling in confined areas. Low noise: Operates at about 25 dBA for quiet background cooling. Durable design: Oil-bearing construction for longer life and smoother operation. Precision-molded, vibration-dampening housing that reduces rattling and protects sensitive electronics. Practical compatibility and use Designed to work across routers, PC cases, printers and other compact devices where space is limited. Fits tight enclosures such as DVR cabinets, NAS enclosures, and alongside CPU heat sinks to address overheating during prolonged gaming or streaming. Quick specifications Dimensions: 70 x 25 mm Power: USB 5V Airflow: 28 CFM Speed: ~2300 RPM Noise: ~25 dBA Bearing: Oil bearing Cable: 93 cm USB Typical applications (how customers use it) Home router or modem: Mount near vents to lower internal temperature, improve stability, and reduce packet drops during heavy use. NAS or DVR enclosure: Add targeted airflow inside cramped cabinets to extend drive life and reduce thermal alarms. Gaming/streaming PC or small workstation: Supplement case or heatsink cooling during extended sessions to avoid throttling without adding loud fans. This fan provides compact, quiet, and reliable cooling where space and noise are concerns, using oil-bearing construction and a vibration-dampening frame for stable long-term operation.
