Pure Base 500DX, weird humming noise

[Schokio]

Hey guys,
using my new case for almost one week, and the last day I started to notice some humming noises.
At first I thought it would be the PSU or something different, but it always disappeared after some time.
It's quite loud sometimes, til I noticed that the sound is coming from the front IO USB 3.0.
By slightly moving it, the humming stops, but gets back after a while.

Is it a common issue, and how can I fix that ?

My first thought is that it might be vibrations. When the humming starts touch the components sse if any of them are vibrating more than expected.

[Schokio]

My first and only guess would be, that one of the included Pure Wings is causing the humming.
But it's quite weird for me, that if I touch the port or put in/out an USB that it sometimes stops.

Like now, it stopped without doing anything. Fan speeds were the same the whole time.

Then it might be the io shield.

@Perrytheplatypus43
To be clear, I am talking about the *front* IO - the humming comes from there

ah that is weird i have no idea. I've hear about audio devices like mics buzzing through the usb but not the usb itself

[Schokio]

Yeaa, first I thought it would be some coil whining. I was surprised that the loudest spot was the port itself

[Perrytheplatypus43]

yeah sorry i got nothing

[Schokio]

But still thanks for your try

[Perrytheplatypus43]

If you have a way of comparing it, is the humming 50-60hz using this: https://www.youtube.com/watch?v=J0a2Prc_MQo&t=101s if so it could be this

[Schokio]

Definitely not such low frequency humming.
Currently I can't say how exactly it sounds, 'cuz right now it isnt happening.

It's like a mix of coil whine, and a squeaky fan.

well when it does please tell me what frequency you think it is. Or maybe record it.

[Schokio]

I tried recording it, but it resulted in rather hearing the fans, and not the noise, even tho the noise was louder.

But I'll try again if it appears.

@Perrytheplatypus43
Just realised, you can hear it in the recording. Just compared it to one that I just recorded.
Both times were the same workload (just sitting with firefox open)

The 10 seconds is the version with humming

It dose sound like a electricity hum. The cause is probably a faulty usb port. I don't think you will be able to fix this if you can and if it annoys you too much you might have to return it (if possible). the common cause is a bad connection between wires.

[Schokio]

It doesn't really annoy me. I only were concerned if something else is bad.
But the USB port is still safe to use, isn't it?

Only thing that annoys me, that I dont know when exactly it starts doing it

you can try to contact the manufacturer and see what they can do about it.

I don't think so i have power strips do the same thing we you plugin more than 2 things i'm sure it is safe. But contact manufacturer to be sure

[Schokio]

I can't contact the manufacturer, because I can't find the damn serial number of the case.

Normally its on the backside, but there is nothing >.<

[Schokio]

Either by a call, letter, or their online formular.
But found the serialnumber ^^

@Perrytheplatypus43
They already replied 2 hours ago. Waay quicker than I thought.
They never heard of such problem as well, but straight up offered a replacement part.

Is that part difficult to replace?
