Vibrations coming from the case

[Assoul]

I own an NZXT H650 and have the following fans in them:

1 x 140mm NZXT case fan on the rear
1 x Noctua 120mm fan on the top.
1 x Noctua 140mm fan on the top as well.
2 x 200mm NZXT case fans on the front.
1 x Corsair SP120 attached to the CPU heatsink.

All of these fans are attached with metal screws to the various parts of the case with the exception of the CPU fan which is attached to the heatsink with metal retainers. What I'm noticing is that there's some audible vibration noise coming from the case. For example, if I remove one of the case panels, a noise that pulsates steadily is gone or greatly reduced.

Is there something you can recommend?

Thanks.

Typically, the first step is to put rubber gaskets/grommets/spacers on anything with a motor (fans, hard drives, etc.)

That will cut out the vibration like 90% of the time.

What spinning hard drives do you have in there. Your pulsating description is eerily similar to the problem I had with my Samsung F3.

Even rubber grommets don't help in my case as there are still the metal screws connecting the drive to the bays.

I've had to suspend the drive within the bay using hairbands, with long metal screws outside the bay stopping the ends of the hairbands from slipping back in.

This has worked for my 2 most recent cases.

I swapped out my HDD for an SSD a couple years ago and found that my case fans cause absolutely no vibration that I can hear, or even feel with my hand. So if you are using an HDD, I'd check that first. Should be as simple as unplugging any HDD's you have and turning the PC on to see if the vibrations still exist. At least you would know what your target should be, if it's still vibrating, maybe you have a faulty fan somewhere.

You can try stopping each fan for a few seconds with your hand (careful) to take notice of any drop in vibration level. That will tell you which if any fan(s) is the culprit.
