So I've had my computer a little over a year and a half now and I happen to look over and noticed that some of the lights on the pump head had come on randomly. They wouldn't respond to the controller (All other fans would work, and the not-already lit up lights on the pump head would work, but the lights that were on would be locked to whatever they were. Upon restarting the computer they responded at first to the controller, but upon shutting off all the lights, several others remained on. I was wondering if anyone has had similar issues or knew what might be the problem. I just recently got the PC back from the shop after having a RAM problem and would prefer not having to bring it back if I don't have to.
