Severe screeching noise coming from PC

[gregl111]

Hey guys,

I put a post up a couple of weeks about a wobbly fan I have that makes a rattling noise, but now my PC is making a second noise, this time it's a high pitch squealing noise, I've only had it a couple of weeks and having this second loud noise now start to come out of it is really disappointing, don't suppose anyone recognises the noise in the video below? You can also hear the ever-present rattling that the fan makes as well.

I took the side of to see if I could pin point where the noise is coming from but I really can't tell where it's coming from.

Here's my setup:

I was going to say Hard Drive, based on the lower toned sound in your video, but that might be the fan you're referring to above. Has to be linked to something with movement so case, AIO or GPU fans are likely suspects.

Perhaps disconnect a fan cable in turn and try and isolate it?

Thanks for getting back to me, that's good to know, I think I'll go through and disconnect each fan over the weekend to see if it's one of them. Are GPU fans something that I'm able to disconnect myself (as someone who hasn't done this before) or would that be something I would have to send back do you think?

You can just stop the fans by touching them with something like a pencil for a second or 2 rather than disconnecting

You shouldn't need to stop the GPU fans. When idle, the GPU fans shouldn't run. If the GPU fans are to blame, then when you first boot, the noise shouldn't be present. When you start a game, the GPU fans will kick in pretty quickly, so if the noise starts then, it's likely the GPU.
