Pump sound issues

[Drew Learns Tech]

So I've just installed my first water cooling loop and it's loud as heck, I assume it because my pump is stuck at high, its PWM but I can't find any software that will allow me to fix it and my bios won't let me alter the curve either. I've tried Speedfan but my mobo isn't listed as supported, I've tried installing ASUS fan controlling software but there is something wrong with the installation and it never installs properly.

if it sound kinda grindy, dont worry, thats micro bubbles circulating through the system, they will eventualy work their way out and the system will quiet down.

If its your pump - let the bubbles work out...or you have bubbles in your loop that need let out...is your reservoir or radiator higher than the pump so that air gets trapped NOT in the pump housing?

 

If its your fans, and you have no easy way - get yourself a multifan fan controller.

i'm having a similar issue; when my pump starts when i boot my pc, it is nice and quiet, but after about 10-15 mins it starts to make a rattleing sound. anyone know why?

Once you confirmed no leaks OP (and new guy) I would then take my computer, unplug cables (not loop lol just whats keeping it attached to the wall and peripherals lol)everything and move it in every direction thinkable to try to get air bubbles to move out of anywhere in the loop to end up higher in the loop.  Im not as sure with custom loops but this works with AIO's and...its basically the same thing.

 

It could be they are just trapped in the pump housing and need to be moved on up to the East Side.

 

EDIT - OP I cant watch videos at work sorry, link blocked

You'd wanna be pretty damn sure you sealed everything up right on your loop so it can handle being upended though. And depending on how you tilt it you could actually feed more bubbles into the system. 

 

OP, how long has it been running for? Looks like you have a DDC pump, they are a loud on max AFAIK (I have a D5, they're bigger but they're made to run at max RPM and make barely any noise whatsoever). But regardless of pump type, you should let it run for at least a few hours straight at max RPM. I turned my pump on and off a few times to try and pulse most of the bigger bubbles out, then left it running for hours and it's clear now, haven't seen any bubbles anywhere.

im sorry for barging in on this thread but i dont want to start a new one while this is alive, ive tried moving it about to get rid of bubbles and it makes no difference and when i look inside the pump there are no bummber spinning here is a video:

Ive never custom looped - curious why anything would be able to leak or move around regardless of orientation? Are they not properly sealed?  Are they not properly secured?  Asking cause Im real curious (I see why you would want to make sure you have it sealed and can upend it, that all makes sense but do people actually...not do these things?)

 

How could air be introduced into the system?  Or do you mean air bubbles currently trapped somewhere not causing issues can now be allowed into the loop to cause issues?

You can never 100% get all the bubbles out of the system AFAIK, they'll work their way into an air pocket at the top of your reservoir and if you upend the system then you're feeding that air pocket directly into the pump and back into the system. And they should be properly sealed, but if you forgot to tighten something down and you put your PC in a weird orientation and it comes loose, that could be a problem. And again, you risk sending the bubbles from wherever they've settled out of the flow of coolant right back into it. 

 

There's no need for drastic measures anyways unless you've ran it overnight or for a day or two and there's still bubble noise. By that time they should all work themselves out and into that pocket at the top of the res. OP has another advantage that he doesn't have a clear block. I have a clear block on the GPU and monoblock on the CPU/mobo, so even though after only a couple minutes of running bubble noise was gone, there were still bubbles I could see and that's annoying. After about a day of running they were all gone, blocks are crystal clear now with no sign of bubbles. IDK about tubing and such since I'm using the same black rubber EK ZMT stuff.

Thank you so much for the response.  Makes total sense.

If the noise/vibration continues after a few days, then it might simply be resonance. Vibration from the pump goign into the case making it louder. Consider mounting the pump on some dampending material to reduce vibration.

 

Open the side panel and grab hold of the pump firmly with ur hand whilst its making the noise, if the noise dies down, its resonance.

 

I personaly use a D5 on its max setting (5), and it used to be loud untill the air was worked out of the system, i also mounted it on some stiff foam between my L bracket and the case which reduced the amount of vibration transfered to the case considerably.

This one sounds like vibrations passing through the case, can you see if unmounting the pump helps the sittuation? If so, you need to get some rubber mounts to dampen the vibration

Can't quite tell if this is an SPC or DDC pump, but this one sounds like defacto pump noise that you'll have to try to address by slowing down the pump (if temps allow) or other brute force methods like sound isolation and/or replacing the pump.

So I'm not 100% sure it the pump anymore. It might just be the fans on the rad. I'm about to try a test with them unplugged to see if that is the issue. It hasn't been running that long and even when I did a leak test yesterday the pump was fairly quiet even at max.

I have gotten some improvement from unplugging the fans and plugging it back in. It is a DDC pump and it runs about 3000ish RPM from everything I've seen so far. At 3000 it is still fairly loud in my opinion and does not improve when I hold in my hand when checking for resonance.

 

EDIT:

Also, I have noticed some fluctuating temps from about 33C to 40ish C so that might be an indication of microbubbles?
