EC 9238 Axial Fan，92x92x38mm Muffin Fan, 110V 120V 220V 240V AC 92mm x 38mm Cooling Fan, Dual Ball Bearing with AC ON/Off Switch Extender Cable,for DIY Cooling Ventilation Exhaust ProjectsProduct Overview

This 92×92×38mm (3.6×3.6×1.5in) dual ball bearing fan delivers 87 CFM airflow at 4000 RPM, optimized for high static pressure in demanding thermal environments (e.g., servers, heatsinks, confined spaces). Rated for 90-270V AC, it supports 24/7 operation with a 50,000-hour lifespan. Prioritizing performance over silence (51 dBA), it features industrial-grade durability, horizontal/vertical mounting, protective guards, and a standard AC power plug (unconnected wire). Ideal for server racks, industrial machinery, casino equipment, and high-heat applications requiring robust cooling.

Notable Features

• 【92mm/3.6Inch Fan Paremters】 92 x 92 x 38 mm (3.6 x 3.6 x 1.5 in.) | Rated Voltage :90V to 270V（Wide Voltage Compatibility） | Airflow: 87 CFM | Speed: 4000 RPM |,the double ball bearing design allows the life of the fan to be up to 50000 hours, and the fan supports 24 hours of uninterrupted operation.
• 【High-Performance Fan- Static Pressure Design】 - Engineered with a 92x38mm high-static-pressure blade structure to deliver concentrated airflow for demanding applications, including server cases, GPU/CPU heatsinks, radiators, and restricted spaces; Ideal for cooling systems requiring enhanced thermal management in compact environments. Also good for custom projects related to casino machines, chicken coops, industrial machinery, arcade systems, and more.
• 【Optimized Airflow with Acoustic Tradeoff】 - Generates 85 CFM airflow at 4000 RPM for maximum cooling efficiency, but operates at 51 dBA (non-silent design); Prioritizes performance over quiet operation, making it suited for industrial, server, or high-heat scenarios where noise is secondary to thermal output.
• 【Industrial-Grade Durability】 - Dual-ball bearing motor rated for 50000 hours of continuous use; Supports horizontal or vertical mounting configurations and includes protective fan guards to prevent foreign object interference in harsh environments.Includes 100-120V AC power plug for direct compatibility with standard server/workstation setups. （The wire remains unconnected to the fan.）
• 【Technical Support】Non-human damage, one year free service.
