Under each knob, we can find the channel number laser etched:

Behind each LED hole, we can find a white plastic film, which give a nice effect:

The FC8 comes with the Lamptron “Endurance” technology, which ensures that the product is built with high quality components; at this model, solid capacitors are used, which can be seen between the two separate PCBs; most of the PCB components have no codes or manufacturer logos imprinted:

On the back of the controller we can find the 8 3-pin fan connectors along with the capacitors and MOSFETs for each channel:

The thick red/black power wires lead to no less than three MOLEX connectors; to ensure proper operation, all three must be connected to the power supply:

When powered on, the LEDs for each channel power light up (in case the knobs are turned a little to the right, and not in the OFF position):

Here is an example when the 3rd and 7th channels are turned off; we can note that even if we do not have a fan installed on a specific channel, the LED would still light up:

By using the channel 1 and channel 8 knobs, we can adjust the color of each LED:

With this feature, we can reproduce the look of the most fan controllers present on the market (a single color for each of the channels):
