Try a power station + turn off circuit breakers in your apartment and make sure your pc is far away from any devices then test it, that will confirm if it’s electricity or not.TheKelz wrote: ↑03 Sep 2022, 03:54So, another weird thing happened regarding my fan. I have my iMac and personal PC side by side, so I usually turn them on both at the same time. Today, when doing this, my fan slowed down so much it nearly stopped as soon as I turned on both iMac and my PC, but then it recovered and went fast again. So I guess I can totally blame electricity now? This is happening consistently.
Not true! Unless the step-down transformer is right before his main electric service panel, with phase neutral and ground coming out of that transformer solely to his electric meter and then to his house and nowhere else.assombrosso wrote: ↑03 Sep 2022, 05:33Try a power station + turn off circuit breakers in your apartment and make sure your pc is far away from any devices then test it, that will confirm if it’s electricity or not.TheKelz wrote: ↑03 Sep 2022, 03:54So, another weird thing happened regarding my fan.

try shutting down and unplugging your iMac from the electricity, there was a video that I posted a while back about a guy having noise on his amplifiers from an old iMac. The noise persisted even when he moved the iMac to another floor using a completely different circuit.TheKelz wrote: ↑03 Sep 2022, 03:54So, another weird thing happened regarding my fan.

What if he takes his pc and monitor and played in an empty area that has no electricity wires or transformers nearby and power it using a generator, would that be enough to rule out electricity/interference? I think it might be enoughThatweirdinputlag wrote: ↑04 Sep 2022, 18:37Not true!
