MB500 fans run but RGB does not

Recommended Posts

I just finished my build, I'm kind of a novice at this but have everything working except the case fans do not light up. These are the 3 fans that came with the case. Case did not have any instructions so we aren't sure if we have plugged everything in correctly. It has a little switch controller that looks like a SATA connection. We tried hooking that up and still nothing. Really not sure where on the mobo the fans are supposed to be connected etc... I have an Asus ROG Strix Crosshair VII motherboard. Any instructions would be helpful. I've been searching half the night for answers.

Hi Lesle LaDuke,


You can connect the RGB fans to the included RGB LED controller from the case and connect the reset switch from the case to the LED controller so you can control the RGB lightning with the reset switch on top of the case ;) 




I have checked your motherboard and your motherboard has also a RGB header.
This means you can connect the RGB fans with the RGB splitter cable directly to the motherboard RGB header without having to use the included RGB led controller from the case.

When you have connect the RGB fans to the motherboard RGB header, you can control the RGB LED's with the Ausus Aura software.


RGB header on your motherboard: 



Let me know if you have any other question.

I just finished my build with this case as well and like OP I'm not well versed in the RGB part of this at all.

I believe I have everything connected right to the splitter/controller however I'm getting fan spin but no lights at all.

I currently have a gigabyte X570 elite wifi mobo and am at a loss as to what to do.

I have the gigabyte fusion software downloaded which doesn't detect the fans and the coolermaster software just tells me to 'Plug in my CM device to get started'

Any thoughts?


Thanks in advance
