Introduction

Today we are testing ZM-MFC1 Combo fan controller from Zalman, which has five independent channels, four with manual adjustment and one with dual control (automatic or manual, compatible with PWM fans). Check it out!

MFC1 Combo, unlike Touch-2000 from Aerocool and NZXT Sentry 2, is a simple controller, using potentiometers to adjust the speed of the fans and coming with no temperature sensor. As it has no sensors, it obviously has no temperature displays or automatic speed control based on the temperature at chosen points.

Its box is simple and small, as you can see in Figure 1.

It also has no kind of audible alarm. However, it is not "dumb" at all: each channel has a dual-color LED that indicates the speed of the controlled fan. Blue means low speed, purple (actually, blue and red glowing at the same time) means medium speed and red means full speed.
