I need help with my case fans.

Sal411

I bought this case when I built my first PC. Every time I turn on the PC, the fans and the RGB turn on, but every few seconds the color blinks off and turns right back on a second later. I have a GIGABYTE motherboard and there are only 3 fan ports, the CUP fan, and 2 other fan ports and they are all taken up with my case fans. I don't know why I can't change the color of the fans when I'm in RGB Fusion!! Like they are not popping up on the RGB Fusion menu. Also, my motherboard box says it can control RGB so?? Idk what's wrong. :(

Also where it says LED and Digital LED, there are no ports for that on the motherboard. I Have no clue if it's just the motherboard or the fans just can't change color!?

You have two headers on the bottom of the board. LED_C, this is the LED on the software. DLED_1 this is the Digital LED, make sure you're picking the right header to change. LED is regular RGB. DLED is ARGB, so it'll depend on which types of fans you have.

As for the color blinking off and back on, almost sounds like the RGB Fusion SDK crashes and restarts, tries to write out to the MCU over and over. Check your event viewer logs, see if there's any apps crashing.

What's the model and manufacturer of the fans you're using?

@Sal411

The fans should have two connectors each. One for the fan header that powers the fan and one for RGB, which probably daisy chains together so that you can use them all on a single header. Is that what you're seeing? And they are 4 pin RGB, correct?

What would the LED_C port be labeled as on the motherboard? I checked to see if it was there, and no ports say LED_C or DLED_1?

@PowerSpec_MikeW I plugged in the 3 main case fans into LED_C. But my 1 other fan has no where to plug in besides the SYS_ fans, and those are the fan ports that don’t work with rgb besides the stupid rainbow that I can change.

Sal411

And the other 1 fan I’m talking about only needs a 3 pins all next to each other without a space between them.

I just tried it with the 3 fans connected to the LED_C port and the rainbow turned on but the fans weren’t spinning. I went into RGB fusion to try to change the color and the color barely changed at all and the only thing that was working was the flash mode. The other fan that was connected to the SYS fan port was working fine but I still could not change the color of it. And I went in the bios to see if something wasn’t working and it said everything was fine. I thinks I’m just gonna have to build a new pc.

They are Zalman case fans. And they say 12 V on them.

Sal411

They came with my case.

I am not Shure about the model but they are black with rainbow RGB.

"One for the fan header that powers the fan and one for RGB, which probably daisy chains together so that you can use them all on a single header. Is that what you're seeing? And they are 4-pin RGB, correct?"

Yes that's correct.

Connecting the fans to the RGB and SYS_FAN header should be all that's required. You'd need to test the fan on another board to figure out if it's a fan or board issue.
