I just bought about 5 fans and mounted them in my case. They each are supposed to glow a bright green insted about 3 of the 5 started blinking. this would not be a big deal if my case was not completely clear acrylic. The weird thing is that when i restart my pc the dont blink until everything kicks in. Could this be a case of low power? Should i upgrade my psu? They are each the exact same model and say nothing about blinking on the cases.
