The ZM-MFC2 comes with a fair amount of hardware. First, we see the CVS (Current Voltage Sensor) At first, I thought it was an AC adapter, but it actually goes between the wall socket and your power supply. There are also fan power extensions, temp sensors, a PCI bracket, thermal tape, and some screws. Finally there is a instruction booklet, mine was in well-translated English on one side, and Korean on the other.
It's pretty obvious that this isn't your normal fan controller.
1-Graphic Power Load Meter: Displays power between 30 to 800W in 4 stages.
2-Numeric Power Load Display: Numerically displays power between 30 and 800W. (The Numeric Power Load Display will read “LLL”when an overflow occurs. “LLL”indicates power loads beyond the unit's measurable range.)
3-Fan Status Display: The Fan's operation status is indicated with animated propeller images.
5-RPM Display: During RPM Setting, RPM is displayed in units of 60RPM, and actual operational RPM is displayed in units of 10RPM.
6-Temperature Display: Displays temperature readings between -9 °C and +99 °C
7-Jog Wheel: Used for adjusting Fan RPM. RPM can be set from 1000 to 5940RPM in units of 60RPM.
8-Mode Button: Used for selecting a Fan Channel and saving the Fan RPM setting.
1-Standard Fans (Fan 1~3): 3-Pin fans that include the RPM output function can be connected for use. PWM Fan (Fan 4): 4-Pin fan that includes the PWM function can be connected for use.
2-Temperature Sensing: Four temperature sensors can be connected.
3-CVS Terminal: Receives the measured values of the CVS.
4-Power Connector: Connects with the PSU's 4-Pin connector.
