Water Cooler causing case vibrations I think

[XanderX]

Recently bought a new PC which has a water cooler. On more intense games the PC vibrates, it sounds like it coming from the water cooler fans at the top of the case. I don't think the cooler is faulty and it doesn't sound like air bubbles (I looked it up on YouTube and its not that). I suspect it's just normal vibrations, its only when the RPMs go up that I hear it but I've never had a water cooler before. I don't know if I can do anything about the noise? If not then I might look at getting a PC mount to mount it under the desk instead.

It's a Kolink Umbra Void AIO 240mm Performance aRGB Water Cooler, the case is APNX Creator C1 Black Mid Tower Case. I've tried putting some rubber furniture feet underneath the case but because the noise is coming from the top it makes no difference.

Would be good if I could find a way to dampen sound so open to suggestions that might work.

If I load up MSI Center and run a game then close it down it MSI shows over 2000 RPMs for CPU fan, then goes down to about 800 within a few seconds. Not sure how to check it in game as Nvidia overlay only shows GPU fan speed. I know what I need to know to get by so sorry if I'm not giving the right information.

I've been testing a few games and so far its only one game, wondering if it hammering the CPU more than the others.

I'll check screws and see if I can work it out but pretty sure its watercooler fans, the GPU fans weren't even getting hot enough for them to come on and case fans were running around 800. I'd say it's vibration rather than rattling. I think rubber washers are worth a go as I can feel the vibrations on the top case directly above the water cooler fans.

I've tried to get MSI Afterburner to show fan speed and I just can't figure it out. I've tried getting HWINFO to report to RivaTuner but honestly staring at a load of white text on a black background is not my sort of thing. I've order some rubber washers which hopefully will be small enough to fix the issue, its easier for me to try to fix this physically that get multiple programs talking to each other.

It does it with DOOM Eternal as soon as game loads up, being playing Helldivers 2 at weekend and noticed it with that also but doesn't seem to have same intensity and doesn't happen straight away.

I've tried the washers and it makes no difference. I think the noise is coming more from the radiator fan towards the back, the one towards front doesn't seem to make it. I think from the side it sounded more like case vibrations, it might be at little as well or also that the sound is bouncy around inside the case a little.

Thanks for everyone's help so far. I'm going to take a break from fixing as it's giving me a meltdown.

I've no idea if the noise is perfectly normal, Overclockers have said it's fine, but because I'm Autistic and sound sensitive it's driving me round bend a bit.

I bought one pre-built as I didn't want to mess about as I've not built a PC for 15 years+. I just wanted it to work off shelf. Which it does just at a pitch that agitates me so I'm kinda feeling stuck now.

Also went with an AIO as I read it should be quieter. I think if I'd got a CPU fan instead I'd would have been better off.

I'm just going to calm myself down and try to fix this another time.

I think my husband has found the cause of the problem.

He worked out that the AI in the MSI center was overriding fan curves. The CPU wasn't even hot (32 degrees), and it was sending the radiator fans to 2400 RPM. The fans for the radiator have a max of 2200.

So it looks like AI was preempting a heavy load on CPU/high temperatures and maxing it out even when it didn't need to. Which is why as soon as I loaded DOOM the AIO's fans were going crazy.

Turned off MSI AI and it's stopped. I'll do some testing another time to see if anything changes once I've been gaming for a bit but hopefully this has fixed it. I'm glad I didn't just accept Overclockers answer as I would have probably worn out the AIO's fans pretty quick if I'd just left it.

The MSI center by itself is working fine to manage it but if I turn on the AI in the center that's what causes the issues. So MSI AI is overriding itself, if I set quiet or balanced for example in the MSI center the AI says no that's wrong and decides to wack the fans up. If I turn off the AI off then it keeps the settings. Although I might just get rid of it completely.

This is what it sounded like before
Noise from AIO.

After fixing it I realised there's vibrations from the GPU too, but so far a blob of blue tack on the back of the GPU has stopped it. I've tried reseating and checking screws and doesn't make a difference. Don't think it's anything unusual though so not concerned.

I think the noise from the AIO and GPU together was making it harder to work out where the noise was coming from.

I can still hear the AIO a bit but only when I don't have my headset on.

I've googled MSI Center AI and I'm not the only one struggling with fan noise.
