hello i just got and installed my Zalman 5.25 bay fan controller model number Zm-mfc1. the product is as pistured and installation wasn't too complicated, but the led's are very random, the first one shuts off when i turn the knob all the way down, and the other three blink when i turn them anywhere past 100%. the 2nd turn knob turns continuously unlike the others which only turn 3/4 of the way. very disappointed in zalman =\
