Everflow 60x60x15mm Dual Ball Bearing Ultra High Speed PWM Fan-R126015BUAF 840556097143 4Pin PWM Connector w/8" Tail FEATURES: Bearing Type: 2 Ball Bearing Material: Housing Plastic (UL: 94V-0) Impeller Plastic (UL): 94V-0 Protection: Current limit/ Impedance Operating Temp: -10-70C PRODUCT SPECIFICATION: Rated Voltage (V): 12 Rated Current (Amp): 0.40 Rated Speed: 2000 ~ 6000 RPM  Maximum Air Flow: 9.4 ~ 29.8 CFM Maximum Static Pressure (mmH2O): 0.71 ~6.42 mmH2O Sound Level: 20~42 dba 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)
