I have just built my first pc and every 5 minutes or so I get a quick squeal sound, really puzzling me, thought straight away HDD, I only have one spinning type others are ssd, but after unplugging it still made the noise, sounds like its coming from the motherboard are.

It doesn't always do it and it doesn't last more than a split second, but as I say it repeats. It's not loud but loud enough to notice ?

could be coil whine. or it could be a bad fan. I would start with looking at the cpu fan see if the cpu wires are pinching it. then look to see if any of the wires are falling into the cpu/gpu fans. I would start then unplugging the case fans. if you still hear it turn off and unplug your pc from the wall. see if you over tighten the power supply and you bent the power supply case into the power supply fan or if the case is pushing into the fan or the vendor over tighten the power supply fan.
