Question Alienware Aurora Ryzen R14 Humming Noise (not fans)

[Rohrzk]

I got an R14 about 5 months ago and I set the alienware preset to "quiet" and it's been running great. Recently it's started making a pulsing humming sound constantly as long as it's on. I thought it was a fan going bad or something so I opened it up and stopped each fan manually with a straw, but the noise persists even when all fans are stopped.
Any ideas what this could be and how to fix it?

Below are details from system info, let me know if there's more I need to provide:
System Model Alienware Aurora Ryzen Edition R14
Processor AMD Ryzen 7 5800 8-Core Processor, 3401 Mhz, 8 Core(s), 16 Logical Processor(s)
Installed Physical Memory (RAM) 16.0 GB
GPU AMD Radeon RX 6700 XT

its probably the AIO pump

They put a 120mm AIO in there, no wonder. It isn't enough really for a 5800x

as for a fix, there is this: https://www.dell.com/community/en/c...quid-cooling-upgrade/647fa22ff4ccf8a8de79d9b5 where they replaced it with a 240mm instead. More likely to survive.

Thanks, this is a bit beyond my PC knowledge. So the bulky square over my CPU is a liquid cooler and probably making the noise? Is there a way to temporarily turn it off to confirm that?

can you show us some photos of what it looks like inside? Upload to an image sharing website and link here.

I see two model AIO in those, it might have a 240 now. does it have one or two fans on it?

you can't turn the pump off while PC is running. Can you use straw to see if it is the cause?

Only other hum source I could think of is the PSU.

This image shows the 3 visible fans that I stopped with a straw

This is a close up of what I think is the liquid cooler and its fan

Overall view, let me know if something else would help.

As far as strawing the liquid cooler, I think that's what I did when I stopped the white fan? I don't see any other fans connected to it but there may be some hidden inside I don't know about.

That is a 120mm AIO. I think the pump itself is under the alien logo on CPU.

make sure its not the PSU fan - https://www.dell.com/community/en/c...king-a-humming-noise/647ebc3af4ccf8a8de2dabce

Getting somewhere. I found the little PSU fans and stopped each and they are definitely both contributing to the noise. The green arrow is just a mild fan noise that doesn't bother me, but the red arrow is the fan that is making the sci fi hum sound, it stops the second I strawed it.

Are there simple solutions for this besides getting a whole new PSU because I'm not very confident about hooking everything back up, I've changed out a PSU before and it was not fun, haha.
