PC Fan Speed Controller - Adjustable Manual Computer Fan Regulator for Cooling & Airflow Optimization | Perfect for Gaming PCs, Workstations & Home Office Setups

Notice: Please note that the controller is a four-wire PWM fan controller can control four-standardized protocols in line for Intel's four-wire fan (all four lines of the chassis and CPU fan are met, a server with more than 97% can control fan violence). Unable to control two-wire or three-wire fan, you can not completely turn off the fan! BF1, BF2 (No.4,5) correspond to FAN1, FAN2 stop alarm function switch. When the corresponding open, the controller will sound (with buzzer needed) and light alarm, fans restored after the alarm is cleared automatically rotated. If BF1 and BF2 are open (ON), the FAN1, FAN2 have any one or two stops, the controller will alarm. Not for: Delta FFR0612VHE, FFR0612DHE, Dimensions 6038, Non-standard anti-timing fan (reverse adjust speed) Feature: Accurate temperature setting and control. The controller only controls the speed of the all standard four-wire chassis fan and CPU fan for Intel. It integrates manual speed regulation and automatic temperature control and speed regulation function. When the corresponding open channel fan break down, the controller will alarm with sound and light (works with buzzle), alarm will automatically eliminated when the fan is rotated recovery. When the temperature lower than the accelerated temperature, then output at the minimum rotation speed; when it exceed over the full temperature, then always output at full speed.
