[SOLVED] RGB not illuminating on ASUS TUF AIO Pump ?

[effingee]

Hello friends,

I just replaced a failing AIO liquid cooler on an iBUYPOWER prebuilt system, and everything works fine except the aRGB on the new pump won't illuminate. The pump is powered by the AIO header on the motherboard, and its 3-pin aRGB plug is connected to an included 2-to-1 splitter that it shares with its 120mm radiator fan. The splitter is connected to the first plug on a 4-way controller behind the motherboard, which is connected to the motherboard's 3-pin aRGB header (not the 4-pin Aura headers). There are 3 additional case fans connected to the aRGB hub. The lighting is controlled by ASUS Armory Crate + Aura Creator. The radiator fan and all 3 case fans are illuminated and tunable via Armory Crate, but the aRGB on the pump is not even illuminated. I've unplugged and plugged, uninstalled and reinstalled, and power-cycled and can't get anything to change. Any one have any ideas? Thanks for your help, if you're able to.

and its 3-pin aRGB plug is connected to an included 2-to-1 splitter that it shares with its 120mm radiator fan. The splitter is connected to the first plug on a 4-way controller behind the motherboard, which is connected to the motherboard's 3-pin aRGB header

Just for testing: unplug the 4-way controller cable from MoBo 3-pin aRGB header and plug pump's 3-pin aRGB header directly to the MoBo. Now, one of two things may happen:

1. Pump aRGB still won't lit up and/or you're not able to control LEDs.
2. Pump aRGB lits up just fine and you are able to control the LEDs.

If it's the 1st case, pump LEDs are toast. RMA your AIO, if you care about those LEDs.

But if it's the 2nd case, what you have, is mixed up signals. Since pump has different array of LEDs and needs a dedicated aRGB header, for it to be controlled. Other than the mirroring signal, you're using with your fans.
