Zalman ZM-MFC1 Combo Fan Controller Review

Operation

When you turn your computer on, MFC1 Combo lits the LEDs from the channels that have fans connected, as you can see in Figure 7. The LEDs from unused channels remain turned off.

Figure 7: Turned on.

As we said before, red means high speed, purple means medium speed and blue means low speed.

The LEDs on the left indicate the current work mode from the channel that is compatible with PWM fans (i.e., CPU fan). Pressing the button above those LEDs the operating mode changes: low (blue LED), medium (purple LED) and high (red LED). Pressing it again, the green LED lits and the fan is now operating under manual mode, controlled by the first potentiometer.
