40mm Slim Compact & Space-Saving Design: With a precise size of 40x40x10mm (1.57x1.57x0.4in), this mini USB fan features an ultra-slim and lightweight design, specially crafted for narrow spaces that ordinary fans can't reach. It fits seamlessly into computer cases, router gaps, welding helmet vents, small aquarium enclosures, and terrariums-effortlessly cooling your devices without taking up extra space. Note: To ensure efficient heat dissipation, the fan operates at an optimal speed, producing minimal noise (25dBA) that won't disturb your work or entertainment
3-Speed Adjustable & Powerful Cooling: Equipped with a user-friendly multi-speed toggle switch, this 5V USB fan offers three customizable gears (Low/Medium/High) to match your specific cooling needs. Low speed at 3700 RPM for gentle ventilation of routers and HDDs, medium speed at 4000 RPM for daily electronic cooling, and high speed at 4200 RPM for rapid heat dissipation of gaming consoles (PlayStation/Xbox) and welding helmets. Boasting 6.1210%CFM airflow, it cools your devices in seconds, preventing overheating and extending service life
Durable Brushless Motor & Safe Design: Adopts high-quality brushless hydraulic bearing motor, which delivers a 35000-hour long service life-double that of ordinary mini fans. It can run continuously for hours without overheating, wear, or performance degradation. The fan is wrapped in a sturdy metal frame with a protective iron mesh, effectively preventing accidental finger injury during operation and shielding the fan blades from damage, ensuring long-term reliable use
2-Pack 2-in-1 & Wide Application: Comes with 2 mini USB fans and a 2-in-1 power cord, allowing you to cool two devices at the same time from different angles-more efficient and cost-effective than single fans. It's widely compatible with various electronic devices: computer cases, routers, HDDs, welding helmets, aquariums, terrariums, PlayStation, Xbox, VR gear, Raspberry Pi, cameras, and more. No complicated wiring, just plug and play for instant cooling
Universal USB Power & Easy to Use: Powered by any 5V USB port-USB adapters, power banks, laptop USB ports, game console USB ports, phone chargers, etc.-making it convenient to use anywhere, whether at home, office, or on the go. The compact size also allows for easy carrying, suitable for DIY cooling projects
