Hi, I am posting again because ... wow am I not surprised! I got a new AIO cooler hoping it will be way quieter than my other one and i think it is broken or something I swear ... I'm going to switch to air cooling. Anyways my pump is making some weird noise and making a weird high to medium pitched spam clicking noise can't tell what it is. It's probably air stuck in the AIO pump but idk can someone help me to identify and solve what the noise/issue is. Or if there even is an issue and should I worry about something like this or is this normal for AIO'S?

OK so eliminated the pump being top of the loop as the issue.

Is the noise actually the pump or is it coming from the VRM fan? The VRM fan can put out an irritating noise (this is obviously subjective) but it could well be this that is causing the noise you dislike and not the pump. It can be disconnected but this has to be done from underneath so will require removing it and repasting etc
 
AFAIK I don't get any noise from my pump, the fans on radiator are known to make noises around 1100rpm but I haven't heard anything from the pump itself

I have been blaming every sound I hear on PC so far so I would know if it was actually the pump making any noises :)

your 6 second video a little short and all I hear in example in his keyboard

i have tried stopping the VRM fan with my finger and no it wasn't the one making the noise, so it has to be the pump, I think air is trapped in it just don't know how to get it out.

see my reply below. their is another video that has the same exact pump sound and is 32 seconds long.
 
are you sure its not the fans?

try slowing the AIO fans down and see if noise still there. Mine make an electrical sounding noise if run over 1100rpm, its more a whirring noise though. I just run them at 950 and I don't get any noise. I am not sure if mine isn't just a vibration between fan and radiator.

your fans being over radiator, it could be them. I have my 360 on the front, the fans are too far from AIO to be indistinguishable from it.

Im 90% sure it's not the fans I even stopped all of them and it's the pump making the noise. I even tried taking the radiator out of the case and give it a light little shake to get out the air that is possibly trapped. inside.

It could be a bad unit, might want to contact Arctic support

pump speed set by the fan speed so if you set them to zero, it should have also been zero
page 2 of this shows fan & pump curves - https://www.arctic.de/media/bb/3c/02/1690272958/Spec_Sheet_Liquid_Freezer_II_240_A-RGB_EN_update.pdf

so it could be the little fan I guess.

Thanks for all the advice. But I will try wait 1 more month to see if it "fixes itself" and hope it does. If It fails to fix itself, I will contact Arctic Support and try get a replacement or refund. If I get a refund, I'm going to make the move to air cooling.
 
i had air on every PC until this one. I just wanted to try water. Corsair H100i died in 3 years... though I not sure if that wasn't software. At least this one doesn't have any software to mess it up.
 
I used air for 17 years and water for 3. Its not really a fair comparison. I would say only 2 of them had good enough air flow to be comparable and thats last two. Last case was purely air flow designed, had 3 x 180mm fans in base. Would have been quiet if I had thought to slow them down long before I did.

I like how AIO take way longer to heat up... downside is they also take way longer to cool down. they less reactionary compared to air.

8 years ago I made mistake setting up a fan curve for my CPU that would turn it off if/when PC got below a certain temp - noob mistake. When CPU fan turns off on air, its way more immediately a problem compared to running a radiator without fans for a short time. Depending on what CPU doing at time, it doesn't immediately cause a panic.

Air doesn't risk leakage but so far I haven't had any of that.

OH YEAH. I forgot to mention. I am new to pc building and I might have done the connections wrong. So their is a 4 pin connector and 3 pin connector coming out of my aio pump and I have no idea why their is a 3 pin connector coming out so i just left it i was thinking it had something to do with the argb but nothing because my argb dosesnt even work, and two 4 pin connectors coming out of my 2 radiator fans. I connected the 4 pin connector coming out from my aio pump to the AIO_PUMP header but I dont know if i should plug it into the CPU_FAN header because it is already taken by the 2 radiator fans that have a y-splitter btw. so can you please tell me where all the connections/plugs go including where the argb connections. I am new and have read the arctic manual but can't really understand it. my Mobo is a (Asus tuf z690 plus wifi d4)

Did you read user manual for your AIO cooler?
It should have explained, where every connector goes.

because many other people saying "put the 4 pin connectors in CPU_FAN" "put the 4 pin connector in AIO_PUMP" .. bluhh ... bluhhh.... bluhh, like im getting confused and need help also yes the manual doesn't help. because it doesnt say like where to plug it it just shows the plugs.
 
4 pin is the fan connector, 3 pin is rgb
the argb cable gets attached to an argb header on your motherboard
it shows you what they are on spec sheet. they both 242mm long.

what motherboard do you have?

Mobo is the (Asus tuf z690 plus wifi d4).

Its just their are three 3 pin connectors, 1 on the aio pump itself and 2 on the fans. Like im way to confused I have tried plugging them in but the argb doesn't work

Pump 4pin fan connector goes into AIO_PUMP header.
AIO radiator fan 4pin connectors go into CPU_FAN, CPU_OPT headers.
RGB connector goes into ADD_GEN 2.(1,2,3) header.

Anyway - please show photos of connectors, you can't figure out.

OH YEAH THANKS I GOT IT RIGHT THEN. except i have a what it appears to be an argb hub at the back of my case it came with the case i think and it can't reach the hub so i need an argb splitter so it can reach.

tell me if i am correct?

can you show some photos? not sure what you are looking at.

My pwm cable is plugged into CPU opt, I can match the fan speeds on its sensor to my AIO speed
The fan cables should all be linked together on AIO Radiator, there is one cable that runs from fans to pump through the tubing, and extends out from the AIO pump with the rgb and 4 pin pwm cables coming out of its end. You shouldn't touch the cables on the radiator.

pump relies on fan pwm for speed. it won't ever report its speed.

are you plugging the rgb cable into the right spot? I see the one on top of mb is Aura rgb header, might need to use Asus software to make it work


pump and fan cables should be on same cable on artic coolers. my one cable attached to CPU-OPT

I did a whoopsies then because when I got the arctic liquid freezer i was confused and the radiator cables were too short to reach the sockets. So, I unscrewed the fans on the radiator and tried to extend all the cables. WOOPS

NOW I HAVE NO IDEA HOW TO ATTACH ALL THE CABLES INTO ONE IM SO STUPID
 
You should have read instructions. the fan cables are short for a reason.. they only meant to extend to each other

It should be fine, other people do that to get more control over fans. You just didn't have to do it.

I can't find instructions on how to rewire them. One video shows how to do what you did.
