Question Weird Fan Noise Situation

[mekyle99]

Hi all. I've had this PC for about a year now, and it's had this extremely odd issue with what I assume is a fan bearing problem. It sounds like a faulty fan bearing, as I've dealt with this issue in the past.

Where it gets weird, is the fact that seemingly periodically, the issue will just completely go away. When it does go away, I can't even get the sound to replicate at all, by giving the PC a little tap or something. But then, a couple weeks to a month later, the fan bearing sound will come back, and now I have to tap it to get to stop temporarily.

Obviously I just need to replace the fan, but what in the world would cause it to act up periodically? I've messed around with a ton of different options, whether it be in BIOS, GCC (Gigabyte control center) and whatever else.

Make and model of the fan(s)? Electronics and mechanical failures can be completely random, whereby you can or cannot replicate the issue on demand. I'm assuming you're manipulated the RPM for the fans from zero to 100%...?

To add, are you working with an AIO or a case fan? Case fans for cheap to mid range cases come with the most basic of fans and aren't meant to be in service for a long while(unless you maintain the case's cleanliness to the nth degree).

IF you have a worn fan bearing it can "seem" to be intermittent, but is not if you examine closely. The problem is affected by temperature of the fan bearing.

When this first appears, the fan makes a bad noise when your system first starts up cold - that is, it has been off for MANY hours. The noise may last from less than a minute to a few minutes, but it will go away and stay away as the fan bearings warm up. If you reboot it is still silent. But if you shut down for MANY hours so it cools off, the noise is back on another cold start-up. Over the space of several months the length of time of the noisy cold start gets longer, but it still will stop once warmed up. The LATE stage of this is the noise never goes away.

All I know about the fans is that they are Armory fans. Yeah, I've manipulated the RPM to test this as well. It seems to happen more when the fans ramp down rather than ramp up.

These are AIO fans, sorry I forgot to mention that. Although from what I've heard, aren't AIO fans the same 120mm fans that cases use as well? Correct me if I'm wrong.

I don't think temperature has anything to do with it in this circumstance. It isn't any different whether its been off for a while compared to not very long. Reboots don't change anything either.

with fan bearings it can either be a bad bearing or bad design at low speeds or mid speeds i had 2 arctic fans that had a odd and rather annoying chirping sound. when it would rev up and down on low speeds it was far worse.

ever fan is slightly diffrent and some orientations can make fan noise far worse others it can be vibration or a stray wire clipping it.

some aio fans are like case fans but others can be high pressure fans which are more about air pressure to force threw the thicker radiators which are called Static pressure fans you do get some hybrid designs.

airflow fans focus on just blasting as much air everywhere instead of a single point straight line to give a basic example.

So which kind of fan should I buy to replace the ones in my AIO? I'm probably just gonna replace both just to be safe. I don't care about how it looks at all.

they should be the same thickness and dimentions as the current fans.

what is your aio called so i can look at what fans it uses.

well that explains alot it looks like this company likes to rebrand stuff that aio pump looks suspiciously looks like

a rebranded ls520

i know cause ive built 3 of those systems and it looks like same mounting kit all they changed was the rgb logo to there logo and used some generic fans.

they are hydralic pressure fans the originals are but without the fan dementions of the current fans its hard to know if they will fit.

heres the cooler i mentioned
https://www.deepcool.com/products/C...uid-CPU-Cooler-1851-1700-AM5/2024/15827.shtml

deep cool notes that the fans with these aio are custom unlike retailer models which run at a lower speed.


https://uk.deepcool.com/company/pressroom/newsrelease/2022/15536.shtml?id=PressRoom


you can also use something like this the issue is if the fans are running of the pump you may have to get in touch with canada computers or the manufacturer and get them to send you new fans you could also get new fans and not attach them to the pump but the cpu header.

id recomend the following as a replacement

again youll have to check the dimentions of the current fans mainly the width as you dont want the screws going any deeper or youll destroy the aio

possible recomendation

if the pc is still under a warrenty contact the manufacturer first either canada computers or the company that made the pc. at very least canada computers can point them out or at least send you replacement fans.

Warranty ended about a month ago unfortunately. They are 120mm fans, I just checked. I'll most likely go with those Akasa ones you recommended as I can't seem to find the fc-120a available for sale. For replacing, is it just as easy as mounting the new fans then plugging them into their respective sockets? I'm extremely nervous doing repairs myself as I've messed up stuff like this in the past, but it doesn't seem too difficult to do.

first of get a measuring tape measure the Depth of the fans 120mm is fine but you need the depth

be careful not to overtighten the fans. make sure fans are facing same direction you took them off.
( overtightening can damage the radiator and cause a leak)

25 mm is the depth of fans ive shown if its the same depth you should be fine.

you wont be able to plug into the pump with the newer fans but you should be able to use the fan header known as cpu fan header you need to plug into that so it reads the cpus temperature.

it tells you what board is in your system but apparently they use 2 boards for this model heres the link to both boards

https://www.gigabyte.com/Motherboard/B650-GAMING-X-AX-rev-10-11-12#kf

https://www.gigabyte.com/Motherboard/B650-EAGLE-AX#kf

there quite destinct one will say gaming on it.

if unsure still you can do system information in windows search bar and find the board model in there.

Yup, I've got the gaming x ax model. Based on the LS520 that you showed, it does say the depth as 25mm, but I will make sure to measure anyways. Does it matter which mobo I have? I'm gonna assume its related to the cpu header.

yep just the location of the cpu header
if they built the pc properly the pump will be in the pump header ( on high end boards theres usually a dedicated pump header and the cpu header will be free for fans. it will be written on the board as well.


. yes but the fans are not the original fans they look a bit thicker so id measure how deep the fans are not all fans are equal size. some are slimmer.

Gotcha yeah I'm definitely gonna measure them to be safe. I appreciate the help! It isn't that bad and it doesn't bother me that much for now but as with all fan bearings they just get worse. Doing PC stuff myself gets me really nervous but I think I can do this on my own.

Hey, hopefully this isn't too much of a necro, but I got around to finally measuring and the fan's depth is 25mm. The only thing I noticed though, is that the fans have wires running directly into the pump. This makes me think that I might not be able to even replace the fans, and would just have to get a new AIO all together.

EDIT: looking into this further, I'm considering just switching to an air cooler. I've read from plenty of sources that the 7800X3D is fine with an air cooler, but I just want to make sure I'm not missing anything.

shouldnt be a issue the pump can control the fans however so can the motherboard there should be cpu pump ( which the aio should be connected to and cpu fan header both are at the top of the motherboard and should be written on the motherboard. and just make sure the depth of the fans that are replacing are 25mm use same screws that came with the cooler. same direction.


id heavily recomend a aio.

7800x3d have 3d cache can make it more thermally challenging.

see image

the 3d cache sits on another chip which can cause thermal interference.

https://www.guru3d.com/data/publish...4709e5c083/2023-01-04-09_51_29-guru3d.com.png

these chips are also designed to push themselves higher the lower the temp.

the advantages of a aio as well is taking that heat away from the gpu area.

f you have a big beefy gpu that sucks power and gets quite hot next to another power hungry component that air cooler acts like a radiator.

reason 1.

i have a 5900x i went water cooling because the 5900x was heating up my 4070 super by 10c.

also make sure that the new fans 5v akasa mentioned if you go with them go into the 5v header on the motherboard for rgb do not put them in a 12v header or youll have a bad time.

Okay I see. How would I go about getting the fans out from the wires that run to the pump? I never figured out how I'd get it unplugged from it. Also was thinking to maybe just get a new AIO entirely but I'm not sure how to check compatibility for those

Near the pump which is attached to CPU there where the wires go there should be a tab

Between your finger and thumb push it down and pull gently it will wiggle out.

What you have in the top is a 240mm radiator. As I said it looks like it's based on ls520 deepcool should fit it's best to have it in the same orientation as it already is.

There should be a few screws holding the radiator in place. And why it matters below

Some guides.
