I have built this PC 2 years ago and the RGB on the Pump was working for a bit until I removed 3 of the fans I had in my case. I had 6 fans in total 3 on each side of radiator. The controller I am using came with the 3 extra fans not the water cooling. I have seen people with same issue having to get replacements but if there is a easier way would love to know my options.
