AquaXtreme 50Z noisy

[Barkerd]

I am interested in this one too as I got rid of my AQZ pumps for the same reason. Hoping the Laing D5 I plan to buy shortly will be better but any advice of keeping pumps quiet would be welcome guys ...

There might not be an antivibe kit but maybe someone has come up with a way of quieting down the beastie?

I personally think the d5 is silent and it comes with a foam pad to place between the pump and the case and seems to do the job Im happy so far and that happy that im buying a second one ;0

Bought a AquaXtreme 50Z, its darn noisy (its on some foam I found laying about).

Water is currently louder than my air setup

Any suggestions to make it quieter?

I'm suprised you're finding it as noisy as that as I thought mine was pretty quiet once the system was clear of bubbles.

Yeah I agree with Nick here - once the bubbles are gone the unit is much quieter than I expected given the pressure and flow rates produced - most of the noise I can hear is down to the sheer velocity of the water flow rather than actual pump noise.

In fact I had the same experience when I was watercooling with L20 and L30 hydor pumps. As soon as the bubbles were gone both were almost dead silent.

The best thing to do though if it's still noisy is as already recommended to use a sticky foam pad. They are awesome if you don't move the system much.

 

[Barkerd]

Yes I think the AQZ was much quieter when the bubbles were gone but there was a constant hum/drone that the pump made. I unplugged the pump for a couple of seconds and the sound went away. I had a sticky pad underneath the pump and did try a second AQZ I had but it was the same. The pump was also bolted through the bottom of the case which I neglected to mention earlier so if you guys got it quiet maybe the sound was vibration mmm? Do all of you bolt the pump down with the pump sitting on a pad or not bother with the bolts or maybe use an anti-viration mounting that I have seen on some sites?

Cheers

Both the D5 and the AQZ 50z are *almost* silent when installed properly. Both have pros and cons, but they are amongst the best high flow pumps on the market without question.

Dave Barker, I know what you mean about the constant "whine" or "hum" but I think you'll find it was because there was still air in the system. Not only that but in my experience securing the pumps to the base sometimes makes it worse. Also how close are you to the pc when in operation?

Hi Phil,

With me sitting at my desk the PC75 with the watercooling setup was probably about 3 feet away on the side of the desk - not on my desk next to my ears or anything like that.

To blead the system on first use I leave the cap off the DD floppy bay res while the pump runs for the first few minutes until the bubbles settle down and the noise level does quieten down significantly, so I am not sure if there is any air trapped. In terms of the positioning I have always just installed the pump in the mounting holes that you drilled in the case thinking if it is good enough for your high standards then it's good enough for me. I sit the pump on the sticky pad and then bolt it thru the case. Once the tubing is all in with typically not much slack it is difficult to retrospectively move the pump. I will be a bit more thoughtful about this next time and leave a little slack and experiment with not bolting it thru the case.

Thanks for the advise guys I think I have a plan for next time.

Just to let you guys know I did not mount my unit anywhere - just wrapped it in armaflex tape (sticky back neoprene) and rested it in the drive bay.

ah-ha there is your problem I am almost certain of it. The Danger Dan floppy bayres. Although a great idea they dont work particularly well with high flow pumps. If you were to replace the bayres with something larger your problems would disappear. I have run into this several times during builds. This is why I have replaced the bayres for a thermotube in the new Storm SLI builds. Silence is golden

Was going to say the AQZ pump was the best/quiet pump ive ever used,the only way i could tell it was on was to touch it.

 

[nick25]

I used to have mine just laying on some neoprene in the spare HD caddy (I say used as I no longer w/c). The bolting through the case could make it worse, maybe - aluminium pc75 can act like a giant speaker amplifying those vibrations.

I was quite suprised how long it took to get all the air out of my loops - about a week in all. I was using a fillport though which I hear takes longer than when using a res.

 

[clone38]

I used the neoprene and rubber mounting bolts you can get as well as the bottom of my case had sound proof matting,mind you like what phil said i had the thermochill res fitted to my case so that may have made the difference.

 

[Phil Stanbridge]

Removing the air from a system can take a while I have to say. The last Storm SLI I built took about 2 days all in all and that was almost constantly on - I had to ditch the bayres for the thermotube option which are simply superb.

 

[unreal]

Mine is noisy too, but I use a t line not a res... but its the motor sound I hear so I dont see how that will fade with a res?
