I have recetly bought a Galahad 360 AIO.
After installing everything I did a test run to see if all rgb, fans and pump would work correctly. On my first boot everything lit up for second then the pump rgb went dark and one fan started flickering.
I have turned off the pc thinking that something was not plugged correctly, but all seemed good.
Double checked, triple checked. nothing seemed out of order. Fans are plugged into the CPU header, AIO into AIO header, rgb to rgb header.
I turned it back on and... now no RGB on on the pump, 1 fan works fine
