Buzzing noise when case is closed (Node 202)

[KuJoe]

This is driving me and my family a little crazy, I have three PCs with Node 202 cases but one of them has a buzzing noise coming from inside of it when the case is closed. I can't determine which of the 5 fans it is so I take off the top while it's powered on and the buzzing stops, I put the top back on and it starts immediately. It sounds like it's coming from the CPU cooler (AMD Wraith Stealth) but nothing is touching the cooler. Anybody with a Node 202 case that's experienced this also? Any ideas how to figure out which fan is causing the noise? I was thinking about putting something in between the top and bottom of the case to prevent vibrations but I'm unsure what I can use. I'm open to all ideas and suggestions.

I've got a Node 202 for my living room PC.

 

Never had the problem you're describing though.

 

It doesn't happen when the top is off?

 

Have you tried unplugging all the fans you can and putting the top back on?

 

If the buzzing stops with that, plug them back in, one at a time to find out which one(s) are causing it.
