[SOLVED] I just built a computer and put 5 RGB fans in the case and plugged them in when I turned on my computer the fan LEDs didn't turn on.

I couldn't find any front panel connectors labeled for LED so how do I turn the LEDs on?

if they are RGB fans, than they have two separate cables.
one for motor control(RPMs) and another for LED control(RGB).

unless the fans are a kit that can daisy chain together, you will need 5 RGB headers to plug them into.
if your case didn't come with an RGB hub, you will have to purchase one.

are the fan's LED cables 4-pin RGB or 3-pin aRGB?

 

[yeetus]

there is one that is 3 pin and the other is two pin

 

[yeetus]

I don't think my motherboard has RGB ports on it

 

[JohnBonhamsGhost]

there is one that is 3 pin and the other is two pin

the other 4 fans are "two pin"?
than they are not RGB.

you will need to list the make\model of the fans and your system specs.

 

[yeetus]

the fans are
R4-L4S-10AB-GP Cooler Master Blue LED Silent Fan 140mm 1000rpm

 

[yeetus]

no, it is the two cords that have a 3 pin and a 2 pin

 

[yeetus]

the 3 pin lead is what I need to plug into the mb?

 

[DSzymborski]

the 3 pin lead is what I need to plug into the mb?

Then where did you plug them into if not the motherboard?

You're going to have to provide a lot more detail. Your equipment and exactly how you're trying to connect these.

R4-L4S-10AB-GP Cooler Master

those are older style LED fans, not RGB.

they have a molex adapter that the 3-pin fan cable plugs into that powers the fan and it's LED.
without using the molex adapter, i don't think the LED will light up.

you would need to plug the fan into the larger 4-pin molex cable.
then plug that molex cable into your power supply.
