Case LEDS not lighting up - B450 Tomahawk

Hi all,

Any ideas? I've downloaded the MSI Dragon Centre but for the life of me I just can't get these to light up.

The three fans at the front are recognised and spinning, so working correctly.

What case is it? I cant get my RGB fans to work in my Phanteks P400A D RGB either.

Ive got the same motherboard and you need 4pin connectors from the case to connect the fans rgb to the mobo, though reading online, the sata connector should still work and it doesnt for me.

Hey, sorry for digging up an old thread but I've got the same problem with the same components. I've tried plugging in the sata cable from the case to the psu but that only lights up the power button not the fans. Did you ever get them to glow?

Which case are you using? Do you fans have another argb cable or just the 3 pin connector.

Hi, yeah i got it working, didn't need anything else. It was just the way i was hooking the fans up. Its a tricky one to explain.

I’ve got the Phanteks P400A DRGB one. I only have the 3 pin one unless I’m a blind ****.

Try emailing phanteks they were very quick to respond. I actually figured it out mid email to them lol. Everything you need you have if you have the same case and mobo i have.

Ive just took the side panel off to see if i can see, but i cant really. Its to do with the 3 pin connectors, make sure you have them all hooked up im pretty sure thats where i went wrong.

Yeah I have the p400a + b450 tomahawk max. I’ll have a look at the 3 pins in a bit, thanks for the help!
