For AVC 9025 9225 DS09225B12U 4-wire double ball temperature control PWM cooling fan
Parameters: Model: DS09225B12U Size: 92 * 92 * 25mm (ie 90 * 90 * 25mm) Voltage: 12V Current: 0.56A Interface: motherboard 4-pin Length: 15CM Speed: 4200 RPM Air volume: 81CFM Noise: 18-40 DBA Fan frame: injection molding, PBT + 30% glass fiber + VO grade flame retardant Blade: injection molding, PBT + 30% glass fiber + VO grade flame retardant Temperature: -20 degrees Celsius to +70 degrees Celsius Storage temperature: -40 degrees Celsius to +80 degrees Celsius Power range: plus or minus 15% of rated power Insulation resistance: greater than 500 megohms Working life: 100000 hours at 25¡ãC ambient temperature Description: The fan has a PWM temperature control function. The normal room temperature is very low. When the temperature inside the chassis or CPU gradually increases, it not only plays a role in heat dissipation, but does not produce too much noise.
