AIO Radiator buzzes occasionally upon restart/boot

[HexHimself]

Over the past week, I’ve had an intake fan of my NZXT Case replaced and my BIOS updated. Ever since I got it back home, my AIO radiator has been occasionally buzzing and crackling. It mostly happens on resets, but can also happen on boots as well. There seems to be no consistency, which can make it difficult to reproduce. My temps are all within normal ranges and no noise is produced while using my PC. 

 

NZXT Prebuilt specs

• Windows 10 Home 64 bit
• B450 AORUS PRO WIFI (BIOS F61a, latest)
• AMD Ryzen 7 3600 Mhz 8 core (NZXT CAM shows it clocking at 4241Mhz, BIOS shows ~3600, unsure as to why, have never personally overclocked anything)
• 2x Team Group UD4-3200 DDR4 RAM
• MSI GeForce RTX 2070 SUPER
• WDC WDS100T2B0C -00PHX0 (SSD, 1 TB)
• NZXT Kraken M22
• Seasonic 110-240VAC PSU

Is the rad higher than the pump here? Sounds like a bubbleburst happening to me.

Here is my current configuration.

As you say, it happens mostly on startups or restarts. Newer motherboards (maybe, BIOS update in your case did it) tend do speed up fans on startup for a couple of seconds to blow off potential dust and so on. Can it be the case, or it is an unrelated sound?

It is possible, I suppose, though it happens inconsistently. I’d imagine a fan speed-up noise would happen everytime I booted it.

On my older systems it didnt happen that way, but on my two last builds it happens every time - very loud for a couple of seconds and than nearly silent in idle state. But I suggest you trying to show it to someone or upload and give a link to check, as describing sounds trough text is somewhat tricky xD. For example, upload short video to youtube with link-only access and share it in this thread.

 

Update: you can check this thread, where people discuss fans boosting on startup.

I’ve uploaded a brief video with audio at the bottom of my original post. The sound never happens while I’m using my PC, only during resets/boots.

I forgot to reply with the photo, my apologies.

Sorry, didnt see it at first. In this case, it definitely wrong.

What I was descibing is only fast fan, and you have some sort of mechanical sound. Check, if your fan is screwed tightly or maybe something is in its way.

 

+ Try checking al the fans in the system: case fans, mobo fan (didnt check, if it has one) and so on. You can try unplugging them one by one to see, which one causes the sound. As it happens on startup, your system wont be damaged from a minute of working without proper cooling, as it isnt under very heavy load.

Radiator is firmly situated and the fan move freely without sound when I spin it with my hands.

Are you sure, the soung comes from a AiO? If you're not 100% sure, maybe try other idea - I've updated my previous message with a suggestion.

I am positive it is coming from the AIO radiator.

In such case I am sorry, but I'm out of ideas. I hope, someone else will be able to provide a working solution.

That’s alright. Thank you for trying anyways.

Caught this sound just today upon a reset. Both louder and longer. Temps all seem fine still, but the noise is disturbing.

[AndersWSP]

That's not a good noise. Sounds like your AIO pump is eating itself.

 

If it coincided with the machine having been moved I'm guessing physical, like a bad bearing, caused or accelerated, by moving it around.
