Hey guys first post here. Having an issue with my H100i platinum SE after in put my new Ryzen 5800x in. One of the fans begins flickering to the default rainbow colour scheme after the computers been on for a few minutes. If I start playing a game the flickering becomes worse and eventually both fans start flickering. It gets to a point where it's so bad and I start hearing the usb connect and disconnect repeatedly as well. I also don't think it's doing its job cooling anymore as my CPU temps go well above what they should be. Finally, if I check the rpm on icue it's showing around 20k + which is obviously wrong. I tried everything. I changed the fans, I swapped the internal usb port it was using. I uninstalled hwinfo as well. Any suggestions? Does this sound like I need to take it back to my retailer?
