Rattling Noise Coming from Inside PC

Lanky94 · 2 Dec 2019 at 09:55

Hello

Noticed an annoying rattling noise coming from PC, its not fans because i unplugged them and its still the same.
Same with GPU the fans only run when required
Its a very new build, no HDD etc and the only old part is my PSU, could that be the problem? but its hard to locate but to me it sounds like it could be coming from nearer the top.
My cable management is pretty good and there arent any cables rubbing against blades etc

Any help would be appreciated

An update, turned psu off on the back and it sounded almost like a fuse blew (a pop) turned it back on and after a few mins the noise stopped.

Its an old seasonic 850w maybe 7 years old

What sort of CPU Cooler do you have?

I'd be replacing it at that age.

If it returns I'd make sure all the thumb screws are done up tightly, especially on the pci blanking covers.

Ahhh OK no worries, I was just thinking to check if it was a air cooler with a fan it may have been loose

Can you unplug the power to the cooler and see if the noise goes away?

Air or bad impeller would be my guess.

Also, which case is it?

I had a weird issue previous where my old power supply was letting off coil whine. I didn't realize what it was at first and it was causing my PC to randomly turn off and all sorts. After a good year or two of accusing my GPU of being a pain I got a new PSU and it fixed everything.

Safe to say, I thought the noise was coming from somewhere else and it wasn't all along. This may be the same sort of issue with you.

Are you able to test another PSU?
