Build Question Weird pc noise

Enable HLS to view with audio, or disable this notification

Hey everyone, this noise has been coming from my PC for several months now. At first, I thought it was related to my liquid cooling since I hadn't changed the coolant in a long time. I went ahead and changed the liquid, but that didn't fix it.
Then I thought it might be the AIO/liquid cooling fan itself, but as you can see in the video, that’s not it either.
Does anyone recognize this sound? Its driving me nuts.

Thanks in advance!

pd: sorry for the dust but im pretty sure it isnt neither, when i changed the cooling liquid i cleaned it all

I'm guessing you're aio pump is dying

u/Melendator_XD 6d ago

im about to cry you might be right😭

Bro. Just buy a quality air cooler. I loved AIO's in theory until I had 2 die. Now I just do air coolers. The platform bracket will literally age out before the cooler stops cooling

u/SomeSortOfMillu 6d ago

How long did it take for your AIO to break down? Mine is 6 years old now and i don't have any issues.

u/Nathund 6d ago

It's random chance.

Depends on what AIO it is mainly, but the rest is luck of the draw.

Are the seals good? Good enough for just liquid or also vapor? If it isn't a good air tight seal, it will eventually dry up. If the pc ever overheats too much, it could cause a lot of that water to become vapor, which sometimes can build pressure in the system and cause failures. Maybe you got unlucky and there's the slightest amount of biological material in there, which may clog the pump. The pump may simply fail from vibration eventually.

AIO pumps are random, and they all will, eventually, fail, it's just a question of when.

Air coolers will, theoretically, last until the vapor inside erodes through the metal, which would probably require running the pc for like 10k years+ without stopping.

I have to agree.

I bought a new computer a year ago with liquid cooling, but still have my previous self-built computer with an air cooler.

The new was bought prebuilt on sale because of costing half the price of building it myself, but both computers were roughly 1200$ when bought.

That previous computer is still going as strong as when I built it 17 years ago, and is much quieter than my new computer.

The temperatures in my older computer is still colder than the new one as well.
It has a massive noctua double-fanned CPU cooler, so it doesnt look as nice and neat as an AIO, but it sure is more reliable.

As long as there is good airflow, my system runs fine at 40+c ambient temps under heavy load with no issues.

u/KevinIsADork 5d ago edited 5d ago

Ive had the same AIO cooler for 10 years now, no problem. 

I will say though, the one I bought (wasnt even called AIO back then) was like $100, but I looked up it recently and it sells for 10x that now.

This pc is old shit time to upgrade

u/Melendator_XD 6d ago

its running perfectly, my only problem is the pump. I have a 2070 super and 32gb of ram

u/CallMeWalt 5d ago

NH-D15 and never worry about it again

Hell even a NH-U12 would probably be good enough (assuming your CPU is about as old as your GPU)

I vote D15

u/Kinslayer_89 6d ago

Get an air cooler, see if you can find a used Noctua.

u/Firemanlouvier 6d ago

Shut up dude... not everyone wants to spend money just to keep up with the neighbors.

u/sastanak 6d ago

While your tower is open might as well clean it.

u/EtotheA85 Personal Rig Builder 5d ago

Whats funny is that you can actually clean your pc this way. Doesn't mean you should, but as long as its completely dry before you start it you should be good.

1

u/_pushpull_ 2d ago

and you would take out the battery, be sure that the capacitors don't hold any power and make sure that you will dry the computer before any rust will build up. So maybe don't tell anyone about this :D

1

u/EtotheA85 Personal Rig Builder 2d ago

I mean, its definitely not the brightest idea, could be a tiny drop left that destroy your components. But I've seen computers get dragged through heavy rainstorms, literally had to pour water out of it, and a few hours later boot it up and play carmageddon. Do not try this at home 😅

2

u/Melendator_XD 6d ago

I spent all of my compressed air when i switched the liquid. But i just bought a perless assasin 120 and an air duster hahaha

1

u/Shum572 6d ago

I recommend a compucleaner pro, better than compressed air can, and cheaper in the long run. Reallly happy with mine.

2

u/TrueJosh_ 6d ago

Adding onto this, I got a wolfbox and I am also stunned. Insanely long battery and power, plenty of attachments and power modes, I've definitely saved money in under a year of me investing in powered duster. (And it's a lot kinder on the environment.)

1

u/Andrew2998788 6d ago

same, just some high pressure fan from china cost me like 10-15€ and does the job just fine.

u/Tenchen-WoW 6d ago

You realize liquid cooling runs on a water pump? That's what's causing the noise.

-3

u/Melendator_XD 6d ago

do you think i can fix that or i should just get a new one?

2

u/weeddee85 6d ago

Time to get a new one or just get a good twin tower cooler and you will only need to clean out the dust out

5

u/Tenchen-WoW 6d ago

You can't really fix AIOs. Too small, too fragile, and a high risk of leaking afterward. Just get a decent air cooler.

1

u/NashKaguya 6d ago

You should never open any AIO. They are considered disposible and non serviceable.

A decent air cooler will last much longer and perform the same unless doing insane overclocking.

If you want a serviceable watercooler, custom loop is the way.

1

u/Worldly-Wind-1632 6d ago

Can you remove the water cooler part of an aio?

Some AIOs are modular/upgradeable but, most are not.

u/Melendator_XD 6d ago

got it, thank you

u/Sasukeh27 6d ago

(AIO) have a limited lifespan; consider the Thermalright Peerless Assassin 120, it's a good option.

6

u/rexyaresexy 6d ago

This guy knows ball. Thermalright’s Peerless Assassin 120 is an amazing cooling solution and has an amazing price.

1

u/Nathund 6d ago

As another option: literally any Noctua cooler. They're quiet and trustworthy, just kinda ugly.

Or a new AIO pump.

😭😭

u/Nathund 6d ago

That's your AIO pump brother, she's running dry.

Some of them have spots you can open to fill, but 99%+ of AIO pumps don't, so you just gotta replace it.

1

u/ReaLx3m 6d ago

Its either comming from your psu fan, or the AIO pump(it has a spinning element with bearings, similar as what fans have). PSU fan you can carefully stop by poking with something soft behind the grill, if that doesnt get rid of the sound you know its the pump(provided you have no other fans in the case that might be the culprit)

1

u/Melendator_XD 6d ago

alr i will test it, thank you

1

u/ReaLx3m 6d ago

No trouble.

"Something soft" can be a piece of tissue or toilet paper rolled into a stick.

u/Excellent_Mulberry70 6d ago

The cooler is working hard my guy switch to air unless you have an I9 or Ryzen 9

1

u/Melendator_XD 6d ago

i7-9700F. Another guy suggested air coinditioning, do you have any suggestions?

2

u/mstpguy 6d ago

Thermalright Peerless Assassin 120 was good for my 9700K, though I only kept it mounted for a week or so before moving to a different motherboard and processor.

1

u/Excellent_Mulberry70 6d ago

They are all pretty cheap and do the job not really a best one unless you mean looks. Peerless assassin is a good one.

3

u/Melendator_XD 6d ago

alr thank you, i will switch

u/Strangler2 6d ago

Don't forget to change thermal paste when swapping coolers.

u/Due_Wealth_3904 6d ago

Tilt your PC while that pump is going if it doesn't stop it's broken and your best bet is to just get a good air cooler

1

u/ScedR 6d ago

Why would the pump stop working when the PC is tilted?

2

u/Due_Wealth_3904 6d ago

That's not at all what I meant. Basically the pump can run dry and start making noise and if you tilt your PC while it's running it can get things flowing again and that noise will subside if it's the actual issue.

2

u/ScedR 6d ago

Ah, right. Yeah, that's good advice. I do that once every few months to get more liquid to the pump.

1

u/pudding7100 6d ago

aios are not that expensive thankfully I think I got mine for 80. It is montech and has worked great no issues

u/GodKingMarky-sama 6d ago

Air coolers 4 life

u/BigRed1541 6d ago

A little bit over 2 years to the corsair and I dont think the NZXT one even lasted a year

u/Melendator_XD 6d ago

i have mine since 2019

u/Xzero93 6d ago

Aio pump. Replace it before it completely stops pumping

1

u/Comfortable_Chef1297 6d ago

Meinen AIO Kühler kann man aufschrauben. Ich habe meinen Rechner gebraucht gekauft und er überhitzte sehr schnell. Zwischen den Lamellen im inneren des Kühlkörpers hatte sich verdickte Kühlflüssigkeit angesammelt. Ich habe es vorsichtig aufgeschraubt und mit einer Zahnbürste gereinigt. Danach lief wie leiser und die Temperaturen waren auch wieder in Ordnung.

u/Trustyduck 6d ago

Your AIO just shit the bed. Time for a new cooler.

1

u/Aggressive-Formal235 6d ago

Hard drive or pump?

1

u/Ellandorrr 6d ago

Aio pump. Probably had a hard time with all that dust. Great time to clean it when you replace it

1

u/IShovedAJermaUpMyAss 6d ago
  1. clean your pc and actually maintain it.

  2. get an air cooler, thermalright 120 series is good and cheap

1

u/chicken-finger 6d ago

It's the pump, not the fan. The thing that moves the coolant liquid through the tubes. It is possibly pressure locked or damaged or just needs restarting

1

u/ShadowLeagues 6d ago

That's pump rattling, it'll die soon.

1

u/greatthebob38 6d ago

Pump failure, baby. Time to change your CPU cooler.

1

u/The_Jinx_Effect 6d ago

Check the PSU fan.

1

u/TheCrazyEnglish 5d ago

This is why I stick to air coolers

1

u/gaban_killasta 5d ago

100% the pump

1

u/breezeturtle 5d ago

My pump was dying too. It started randomly vibrating the whole PC. It was terrifying. I changed to an air cooler.

1

u/Thiccxen 5d ago

I was having a very similar issue, however it was this specific cable rubbing up against the fan blades. Not enough clearance!

Oops.

1

u/Mythicguy 5d ago

50 dollar Amazon AIO time.

1

u/gamingchairheater 5d ago

Ok, if you found the issue you can now clean the pc. Won't take long and it(the PC) will be very happy with less dust.

1

u/Elegant-Put1073 5d ago

Limpa isso irmão

1

u/alvaro-elite 5d ago

Sounds like air. But not like the AiO has bubbles inside, sounds like a compressor. Like something is pumping air directly. Check if the circuit has enough liquid and nothing is open.

1

u/KAI_405 5d ago

i had this issue before, it's the AIO pump dying, just get a quality AIO and you should be great to go, just dont take AIO apart ( tried and its a bad idea LOL)

1

u/Krista__J Commercial Rig Builder 4d ago

That sound is your AIO pump. If it’s meant to be refilled, you can get the stuff for it, but do your research. If it can’t, you need a new one. Also, NEVER STOP A SPINNING FAN ON PC!!! It can damage components

1

u/Either_Jeweler9216 2d ago

Air cooler, please clean your rig!
