New Aquacomputer D5 pump has become noisy after only a couple of weeks
Hi everyone
Only a few weeks ago I finished my latest watercooling loop. I used an Aquacomputer D5 PWM purchased new from Aquatuning and it was very quiet for a few weeks, but now it makes the noise in the video. It gets worse at certain speeds but can be heard all throughout the entire PWM range. The pump was running at around 2400RPM (10% PWM) in the video. If you can't hear it try turning the volume up, it was recorded on my phone but it's particularly audible and annoying when the system is at idle (fans at 600RPM, relatively quiet environment). I'm assuming this means it's faulty and I have put in a request with Aquatuning but incase it might be something I can fix myself, has anyone here heard this before? Any advice? It's very odd, I've never heard of a D5 pump going bad this fast (other than maybe those Alphacool VPP D5 copies). I doubt Aquatuning will do an advance RMA so unless there's something I can do to fix it I will need to try and return for a refund so I can buy another pump elsewhere first, otherwise I will be without my PC for however long it takes them to replace it. |
Did you take the pump apart and check the impeller for anything in it? Might want to do that before going RMA. I’ve only had one D5 make noise and it was right after fully bleeding a system and then running it at close to full speed. Never found anything wrong inside and it was replaced by EK.

Check impeller as suggested. Use some specific product to clean it and should be fine!

When I take it out I'll check it for debris again. |

Hi,
Only time I've notice sound from my pump is if there was a clog. I use filters they catch what I don't want my cpu/ gpu blocks to catch :) |
Recommend a better fluid in that case.. Also the Alphacool and AquaComputer VPP/D5/Other series are certainly not copies.

I wouldn't rule out electrical noise yet, but, as others have said... check the impeller. It should be pristine even if it's 2 weeks old; mine is 4yo and still is. Besides that, are you sure it's not a coupling/vibration issue?
