Let’s check out how each channel functions. On the right, there is a red LED power indicator. ThermalTake states the DC output is between 4-10v so let’s double check these voltages. Checking out channel 1, we find that the individual blue LED indicator light comes on once a complete circuit is made (fans connected).
With the slider all the way down in low position, we find that the minimum voltage supplied is 6v which is obviously pushing more power than stated.
Checking the max speed of channel one is giving a full voltage output of 12v. As to why a max voltage is claimed, the fan controller provides the correct 12v output to all channels on max speed or while the sliders are all the way to the top. We also find this output on every channel.
I began testing the remaining channels separately, starting from low and slowly moving to high. While the voltage output stayed steady at 4v in low position, the voltage peaked out at 12v in high throughout channels 1 through 5.
