I have the 2 fans at one side, and pump on another. I 've tryied all combos that i can think. Fans+pump together, only fans, only 1 fan, trying all the sides. One more clue, is that when i connect the pump at the same side with the fans, the pump's rgb doesnt work either. Also, i don't have an issue with rpm now. Fans and pump are controller as intended.
