    SMD coil whine "chirps"

    Does anyone have high frequency sensitivity hearing and a motherboards have tons of sounds coming from it? Is this just coil whine en masse? When data to the SSD has high I/O I can hear the clicks and chirps. Same with when the graphics drive inits. Network adapters, chirping after I connect the cable

    I can hear everything. Every time I put my ear to let's say an open Shuttle XH series pc (currently working on) in the next room it sounds like I'm in the middle of a the fucking public bird aviary

    Of course this isn't just the shuttle, though I think the small case makes everything closer together for me to pick it up

    I've heard it in routers, switches, sometimes TV's. I know my deaf ear has had a sensitivity to high pitch noises and this has been bugging me for way too long. I know Tiny SMD coils can cause this but it seems like someones the Silicon on the APU makes a noise, but I know there is small coils under the CPU.

      Normally the issue is with large coils and transformers.
      But sure ceramic SMD components are phonic too.
      But weather it is all in your head or not I can't tell

      Here's an interesting video on it: EEVblog #855 - Ceramic Capacitor Piezoelectric Effect

          I'm not sure but if strange cases i've seen with my own eyes and ears , there was a buzzing fluorescent shutting a Tv intermittently , and sometimes starting it , and an old reel tape catching some specific radio station , while it's not a tuner equipped ..

              ADP-160FR ps4 slim PSU, shuts down under load and has severe coil whine.
              by Gjackson
              Hi all, the PSU originally had a no 12v issue where as soon as I bridged the 5v standby to the ACDC_stby the psu would switch itself off completely. I monitored the voltage on the main filter caps while doing this and saw that the PFC was bringing the voltage up to around 360vdc before shutting down. Given that I saw that as a little low I replaced the PFC feedback resistors from a donor PSU and that got it to power on, without a load no coil whine is present and there is a stable 12v however as soon as I put it in the PS4 it starts whining really badly, however 12v remains stable but after a...

              LG Flatron starts w. coil whine and power issues
              by Bitvive
              Hi ,

              My old LG Flatron recently started with coil beeping. This got worse every day for a few days until it also started having power problems.

              Now it also went off again after displaying the LG logo, then on, off again, then on and so on...

              So far I have measured the power supply unit, which delivers 19.21V and should therefore be OK. I removed the circuit board and connected it to the mains plug so that I could hear the coil beeping.

              During the beeping, I pressed on the coils with a non-conductive tool to see if the sound changed and to find...

              Coil Whine , buzzing, identifying parts R9 Fury
              by 90Ninety
              I have an R9 Furty Nano ( R9 2XX IIRC ) that I want to put to use , I got it on ebay for quite cheap but, it has some of the worse coil whine I have heard .

              I tried putting a long tube on my ear and hovered it around the card while in use , I cannot pinpoint it . However I my educated guess is , that it the whine is an inductor coil and it is one or all of these in the picture . Does anyone know what part this is and what part I can replace them with .




              Perhaps likely is that I am missing something else it could be , here is a stock picture...

              Boston Acoustics Soundware 5.1 SUB: Agonizing coil whine!
              by Jumme
              So. Had my Boston Acoustics subwoofer for 4 years and it had a terrible coil whine squeal from day one.

              I RMA'd it twice, but both times it came back (after a 6-8 weeks return time) and had the exact same problem.
              Said they "swapped the amplifier module". As it didnt help, personally I feel more convinced its the PSU module. Company now bankrupt and I cant stand the noise:

              Its a high pitch coil whine tone -it's terrible agonizing, when worst, I hear it clearly 4-5 m from the Sub (because sits in corner).

              It wines without RCA input....

              PS4 pro power supply coil whine
              by satouri abdellwahed
              I have a PlayStation Pro that has a buzzing and ticking sound from the back on the side of the power supply. I searched for a solutions , i tried to make reflow for some of the components but it did not work. In addition, I used silicone on parts on board without any changement. I discovered that if I make a short on the IC in the left corner, the noise stops. Is that dangerous?
