Weird loud sound coming from the rear fan

asch75

Hi,
I purchased a Duduauto 5 4G-64G, on april 1 2025 at Aliexpress DUDUAUTO Flagship Store and I'm super happy with it.
From day one a noticed a low buzzing sound coming from the rear spinning fan, but it's barely noticeable listening to music or podcast.

Recently the fan started to sound weirdly very loud, probably the ball bearings are defective or no ball bearings at all.
If I give the unit a gentle tap it stops for a while.

Can I replace the fan or do I need to return the device?. I'm an skilled guy, I know how to solder, etc.. just wondering wich fan model / part number do I need exactly. It's the unit easy to disassemble? It's the fan soldered?

Thanks in advance!

asch75 Contact the seller and send him a video. Maybe he will send you a replacement part. I am not a member of the DUDU team, just a forum member with a piece of advice.
