[SOLVED] Case RGB not working after adding fans

[JohnnyGui]

I have a PC case with case RGB light around the glass panel. You can cycle through the colors by pressing a LED button on the case front. The RGB is not connected via the motherboard but by small pin connectors that comes from the front panel.

Normally when shutting off the PC and starting it up again, the PC remembers which color I chose and lights up at boot.

I have added two white LED molex fans of 0.18 Ampere each. These 2 molexes are chained together and are parallel to a chain of 5 other molexes (one of these 5 molexes powering the RGB).

Now when starting the PC, the RGB doesn't automatically light up at boot anymore, even when disconnecting the fan molexes. However, when pressing the LED button the RGB lights up fine and I can cycle through the colors,

What is the issue here? If it's a power issue, shouldn't the RGB not light up at all even when pressing the LED button?

are these just static LED fans with no RGB options so no LED cables necessary?

not exactly.
it may just take a bit longer for the case LED controller to recognize that the fans are connected and for it's onboard memory for your previous setting to initialize.
the fact that it fails to initialize at all anymore can just be low quality case components that aren't fully functioning anymore for some reason or other.

try disconnecting the case RGB cable and any power to the front panel LED controller,
shutdown / power off the system,
hold the power button for 3-5 seconds until all power has discharged from the system,
start up once and shutdown again,
reconnect the case RGB and front panel LED controller, not the new fans, and power up again.

if it's still not functioning correctly then the controller is likely not going to function correctly again.
case manufacturer should approve a replacement front panel controller if this is the case.

to avoid any chance of this happening again avoid that same configuration.
get different fans or a better power supply that offers separate molex connection.
a better option may be to get an LED hub that you can connect better RGB fans and the case LEDs to and sync them all together with motherboard control software.

Thanks for your detailed reply.

They are static white LED fans.
I've tried your suggestion but it's still not working.

I'm really curious what could possibly be the cause of this. Why would it work normally when pressing the LED button but it doesn't automatically go on anymore at boot after adding new fans and even when removing them?

There are 3 lights on the glass panel, each with a small pin connector. Could switching the 3 connectors when connecting it to the front panel wire be the cause?

How about fast boot in Windows? I have disabled it along with hibernation to save space, so the PC completely shuts down. Could that be a cause?

what do you mean?
all case LEDs should share a single 3 or 4pin RGB cable that connects to the front I/O panel.
include an image of this interface where the case LEDs connect to the front panel.

what case is it?

would have absolutely nothing to do with the case detecting or initializing LEDs.

just contact their customer/tech support, explain the situation, and they will walk you through getting the proper replacement.

It's an Azza Taurus 5000. Unfortunately, Azza is not selling these cases anymore and they don't have the necessary replacement parts.

Here are the 3 cables from each of the 3 LEDs on the glass panel connected to three wires that goes to the front panel.

would have absolutely nothing to do with the case detecting or initializing LEDs.

I was thinking because hibernation puts the PC in a lowered power state (instead of no power at all), the front panel would still receive some power and thus being able to remember the previous LED setting when booting up the PC again.

try disconnecting the case RGB cable and any power to the front panel LED controller,

Just to make sure, you're saying I should disconnect these while the PC is turned on? If yes, can I try disconnecting the whole front panel cable that is connected to the motherboard? Would that be safe while the PC is on?
