Lan boy and LED issue

I just swapped out an older motherobard, GPU, and Memory for some newer parts. Long story short is I did some spring cleaning (well I am starting to) and I found an Intel motherboard and a e6300 C2D sitting in a box still sealed in their factory boxes. I bought the bundle on a whim like 2 years ago and forgot I had it.

So I upgraded my HTPC and put the new hardware in my Antec Lanboy case. Now the LED lit fans blink constantly, where as before they LEDs just came on. The blinking is damn annoying, and I found no setting in the BIOS of the board that would do that. The LEDs did not blink before either with the different hardware....

Anyone ever seen this before?

Is it possible the fan has a setting with certain motherboards to blink. I have some that blink but are on a switch to go solid or blink.

To rule out the blinking i would manually wire it up to a power supply plug and see. If it dont blink it might be a bad plug on the motherboard intermittently giving low voltage to the fan causing the blinking.
 
How fast is it blinking? Maybe it's some sort of PWM for controlling fan speed. Have you tried changing the fan speed to full?

It is like a strobe light, I think I am just going to pull those fans and replace them since fans are cheap, and get ones with no LEDs
 
Ya sounds to me like the PWM frequency is to low. It should stop if you put the fan full speed though...

I guess I can mess with the BIOS settings for the fan. It is only a 300w PSU in there (true wattage) but I am only running 2 HDs, a GeForce 210 and cpu + mobo, so its not like I need that much power.
