Why does my pump make this noise?

[Waynelu127]

I have a 72x Kraken liquid cooler, it keeps my temps recents but the noise it makes is awful!!! 

 

Here te is the link to the video 

 

Should I think about changing to air cooling, this is my second kraken and it’s still super annoying.

 

CPU: i7 9700k

loud pumps are usually from them dying or air bubbles, but i don't think it's either of those. If it's too annoying to tolerate switch to a different cooler. Not sure why it's doing that but i don't think its anything to worry about

It makes this sound all the time? Or when PC is under load? Because it sounds more like coil whine from the GPU.

It sounds like this most of the time. It stops for a bit but then continues again. I’m pretty sure it’s coming from the pump becuase the noise is mostly concentrated there, however could a RTX 2080 have that bad of coil whine?

if it's under load, yeah. generally though, cards are dead silent when they're not under load.

 

have you got the pump on PWM control or set to run flat-out?

I control it through the CAM software. I have it on performance I think, but on silence it makes just as much noise. The issue is it can always be heard, and gets quite annoying. I don’t know if I want to drop a ton of money on a aircooler, and my liquid cooler was $170 and I’ve only had it for half a year. I really need a solution

see if there's an option to set it to run 100% duty cycle - there's a slim chance that what you're hearing is PWM carrier signal but honestly it's more than likely just regular pump noises

 

it doen't sound like there's air in it or anything because that makes a very distinctive wooshing sound, or if the pocket of air is big enough, it may even audibly scream

Thank you for the response, however does this usually happen to liquid coolers? Ive always thought liquid coolers were efficient and somewhat quiet, but I sent back my first kraken 72x because of some loud noises and now this one is loud too. My PC always has a high pitched hum. It seems to be from the CPU but it’s just so annoying. 

 

Is is there anyway I can isolate the sound and make sure it’s the cpu?

cpu's don't really make any noise, coils around it might.

 

liquid coolers are inherently noisy things due to a high speed pump spinning round in there and the electronics to drive it. they're more efficient, but not always quieter

Oh okay thank you. 

 

Could my lack of intake affect my the noise? I have three 120mm fans pushing air through a radiator on the front. My RTX 2080 runs at around 70°, my CPU runs at around 65° ,on R6 atleast. Would moving my 360mm radiator into the top help at all? Is the noise possible due to the temps in anyway?

Sound like coil whine to me.

Is there a way to reduce/stop coil whine?

Nope.
