What is this sound?

[MrChavelo]

For the last week or so my custom pc (built about four months ago) has been making this weird grinding noise when booting when it's been off for multiple hours. After a minute the sound stops and everything turns normal again. I think it's a faulty fan, because my HDD is working properly without any issues. What is it and should I worry? Video below. I'm using the standard fans of the S340. Full specs in sig.

Take the sidepannel off and locate the sound to a component!

Sounds like either a faulty fan, or something caught in one of the fans to me... check your computer thoroughly to make sure there are no cable ties or soemthing catching in the fan.

it might be the PSU's fan

they often get this noisy

Do as @A Guy Eating Cereal said

That is almost certainly a fan. Either a fan is hitting something like a wire or is pressed up against the chassis, or is about to fail. Unplug each fan in turn to see which is the culprit, and if none of them seem to be, then it may be your PSU or CPU fan. From the look of how that CPU fan is spinning, I'd lean towards it.

Put your finger on a fan and see if the noise stops.

It's clearly a fan. Once you know what's making the noise you can fix it either by clearing what's making the sounds (like a cable hitting it) , removing the fan or dust cleaning it.

 

Or it could be the case vibrating which you will need to do work to fix.

That sounds like your PSU fan bearing failed.

it seems like your Be Quiet fan isn't really doing it's purpose.
