Evercool 40x40x15mm PWM Fan with Connector-EC4015SH12BP
Evercool 40x40x15mm PWM Fan with Connector EC4015SH12BP 840556100386 Long-life, with low noise, efficient cooling. In this series, we have a great fan to provides better cooling efficiency for computer and hard disc. Silent fans can both enhance the convection and cooling efficiency. In addition, long-life bearing makes fans life get longer it could efficiently extend fan's life, and reduce fan replacement frequency. FEATURES:PWM FunctionDual ball bearingLow noise & high airflowLow pollution (ROHS compliant) PRODUCT SPECIFICATION: DC Fan Size: 40x40x15mmBearing Type: Dual Ball BearingFan Speed: 3000 ± 25% -10000% ± 10% RPMLife Time: Over 50,000 hrNoise Level: <10 ~ <32 DBARated Voltage: 12 V.DCVoltage Range: 7VDC~13.8VDCRated Current: 0.08AMax Airflow: 14.88 CFM Note: PWM Fans are not variable speed control fans on their own. An integrated circuit varies the speed and airflow of a fan using a pulse-width-modulated (PWM) voltage in response to temperature or system commands send typically by a computer motherboard. You can use them to run at full speed from an external supply if you adapt the plug. (PWM Adapter Cables)
