Hi there! If this is in the wrong place, please just remove it. I recently bought a MasterKeys Pro S in used condition, and at first, everything was fine, until the Keyboard started to make loud whining noises, like this high frequenzy whining. But it only occurs when one or more LEDs are set to 180-230 (in the Coolermaster software). For example, a less intensive white (225, 225, 225) is whining like crazy, but a full white (255,255,255) is deadsilent. Is this normal? Never owned an RGB Keyb
