Strange liquid noise (not liquid cooled!)

[boybiffa]

Hi everyone,

I recently purchased a new (to me ) computer. The specs are as follows:

Asus Rog strix b450f gaming (rev1) motherboard
And Ryzen 5 3600 CPU with be quiet black rock 4 heatsink+fan
Sabarent rocket nvme m.2
Corsair 8gb (X2) 3200 ram
MSI gtx 1660 super GPU
Seagate ironwolf HDD 3.5"
WD 3.5" hdd
WD 3.5" HDD

X3 noctura x120mm fans two front 1 rear
Cooler master gold 650w PSU

It's a little over a year old runs brilliantly without any real issue with the exception of a strange noise.

When hammering the cpu at high load, a liquid /airlock type tinkling noise occurs. Only lasting a mere second or two but is noticeable. It happens a number of times say, within a ten minute time frame. (Similar sound to an airlock in a house radiator).

So far I've unplugged the fans one at a time to try and pinpoint a failing fan bearing etc but no joy.

I'm going to try a few things such as unplugging the hard drives and try a different graphics card but not sure this will highlight anything.

There's no liquid cooling in the system so really not sure what could be causing it.

Any help will be hugely appreciated!

Many thanks
Rob

Honestly, sounds like it might be coil whine, which has appeared due to 'age'.

My gtx1060 6GB has an occasional 'click/tinking' type noise when under load, first thought it was a fan catching something but it wasn't.

I believe it's just the expansion of metal from the CPU cooler itself, I have a phanteks air cooler that makes a similar noise.

Thin sheet metal like that just resonates, you can make a similar noise by pinging one layer of the heatsink with your nail.

Thanks for replies ,
I've stripped the machine down today and inspected every closely and reassembled with new CPU paste etc and it still does under heavy load. I've also tried my old graphics card in the machine and it still does it.

Not being able to pin point what it is, is the most annoying part. I'll try pinging my nail on the side of the CPU cooler and see if that replicates the noise, would just be nice to know what the cause of the noise is just for safety's sake as the machine is left running overnight etc.

Thanks

Rob
