Evercool 40x40x10mm 12V Dual Ball  PWM Fan-EC4010TH12BP

840556022626

Long-life, lower the noise, efficient cooling In this series, by strong wind to take away the heat noiselessly it provides a 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:
Long life bearing.
Low noise & high airflow.
Low pollution (RoHS compliant).

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.
