Oscillant noise poweredge t440
I changed my power supply earlier this week, the fan was not spinning and there was a high-pitched noise coming out it. Now the power supply is working fine but now I have this oscillating noise that comes and goes. Even when I am restarting, I can still hear it. How do I determine where is coming from? Any ideas anyone?
The server is pretty quiet, or at least it was.

GustavoMiler,
Without an example of the sound it is making it would be very difficult to isolate the issue. If you were to upload a video of the occurrence with sound we can see if we can help.

@DELL-Chris H Yes, you are absolutely right. The noise is not constant, it stopped now, but when it goes it goes for a while. Here is the link AUD-20250401-WA0001
If you cannot open perhaps, I can email it.

We aren't able to download it due to security reasons, and it wouldn't make it through our email. I would suggest uploading a cell phone video directly to the DCF page, if possible.

Yes I did, from your description of the issue, as well as the sound, to me it sounds like an issue with the power supply fan. If you have redundant power supplies you can remove the new one and see if the sound is gone, then it is a safe bet there is an issue with the new power supply.

@DELL-Chris H It is possible, I was listening closer today and it seems to be the power supply. Now, I just purchased this power supply. I will have to get another one. Can I get this from Dell? The one I have I got it from Amazon. Any help here would be appreciated.

Sorry, the confusion was caused by me as I wasn't seeing the complete list, and the T440 is showing 450 and 495 watt power supplies as well. The one that you showed the image of is indeed supported, being part # YGF8T, so if the part number of the one you ordered is the same then it will be fine. The issue you have though is that the power supply you received was faulty.
