I recently bought an aio 1st player mothra mt240 cooler. Since I installed it in my pc I hear this sound that personally annoys me (I'm talking about that sound like a pulsating vibration ) I don't know if this is normal or a problem with it. I mention that the cooler is mounted correctly.
I did several tests and noticed that it disappeared after I disconnected the radiator mounted fans ( I removed the cpu fan plug, and just left the pump active). After I plugged it back in the sound returned. Does anyone have any idea what causes this sound?
