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.
