Why is my computer making clicking/ticking noises?
My iMac is making weird clicking/ticking noises. Thought it was the hard drive, so I put in an SSD, and went ahead and upgraded memory to 16GB, which didn’t solve the problem.
I can reproduce the sound by running a GPU benchmark, or just opening every app, and will continue for up to 60 seconds after I shut down and unplug the machine.
Thought it was the power supply, but I replaced that and still clicking.
I don’t think it’s the fan because I can spin it up to 2800 rpm with smcFanControl, and it has no effect on the sound. Spinning up the fans doesn’t cause the sound to speed up or slow down, or change in any way.
I don’t think it’s the speakers because if it was, the sound should stop the second the machine shuts down, or at the very least the second it is unplugged, but the noise persists.
I’m out of ideas. I just want the clicking to stop, and I don’t know what to fix that will make it stop.
Here’s a link to a video of the noises the computer is making. This is a video I took of this specific machine.
