I have an enermax 120mm blue LED fan(3-pin). A week ago i installed it to my motherboard's aux rear fan header and everything was working great. Just today the LEDs are blinking (as fast as a strobe light). It is still in the same fan header as it used to be when it didnt blink, there any reason/solution to this. Its just a personal thing, but blinking LED case fans annoy me.:laughing:
