Occasional Vibration

That's most likely a fan that is not completely weighted out (the spinning part) or with a slight bearing damage.

 

As long as it only occassionally humms, and the machine is not moving around due to the vibrations, try to figure out which fan it is, and get a repleacement for your shelf, for when it needs to be swapped out. 

 

 

Main System:

Anghammarad : Asrock Taichi x570, AMD Ryzen 7 5800X @4900 MHz. 32 GB DDR4 3600, some NVME SSDs, Gainward Phoenix RTX 3070TI

 

System 2 "Igluna" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

System 3 "Inskah" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

 

On the Road: Acer Aspire 5 Model A515-51G-54FD, Intel Core i5 7200U, 8 GB DDR4 Ram, 120 GB SSD, 1 TB SSD, Intel CPU GFX and Nvidia MX 150, Full HD IPS display

 

Media System "Vio": Aorus Elite AX V2, Ryzen 7 5700X, 64 GB Ram DDR4 3200 Mushkin, 1 275 GB Crucial MX SSD, 1 tb Crucial MX500 SSD. IBM 5015 Megaraid, 4 Seagate Ironwolf 4TB HDD in raid 5, 4 WD RED 4 tb in another Raid 5, Gainward Phoenix GTX 1060

 

(Abit Fatal1ty FP9 IN SLI, C2Duo E8400, 6 GB Ram DDR2 800, far too less diskspace, Gainward Phantom 560 GTX broken need fixing)

 

Nostalgia: Amiga 1200, Tower Build, CPU/FPU/MMU 68EC020, 68030, 68882 @50 Mhz, 10 MByte ram (2 MB Chip, 8 MB Fast), Fast SCSI II, 2 CDRoms, 2 1 GB SCSI II IBM Harddrives, 512 MB Quantum Lightning HDD, self soldered Sync changer to attach VGA displays, WLAN

It could be some set of fans resonating at some rpm range. The rhythmic volume increase decrease type of sound can be produced when multiple fans rotate at almost but not exactly the same speed. When there is a slight frequency difference between two sound sources, their sound waves peaks and valleys interfere at times strengthening and at times weakening the resulting noise. https://en.wikipedia.org/wiki/Beat_(acoustics)

CPU: Intel i7 3970X @ 4.7 GHz  (custom loop)   RAM: Kingston 1866 MHz 32GB DDR3   GPU(s): 2x Gigabyte R9 290OC (custom loop)   Motherboard: Asus P9X79

Seems like a fan bearing issue. Try take the fan out that you think is making the noise and see if it goes away. If it does go away, keep the fan or replace it.

Hmm so since you said it was a fan bearing issue I decided I'd narrow it down by simply comparing my gpu fans vs my generic fans. Apparently it's one of my gpu fans making the noise.

Seems there might be dust clogging it up. Take the GPU out and use a small brush or air compressor to blow any dust out that may cause the vibrating.

hi.
