before replacing the fans, carefully take them apart by removing the rubber o ring from the shaft under the sticker and use some lithium grease on the bearing..
i did mine and now they are completely silent and been going for months.
Thanks for the tip! ordering some grease now, hopefully that does the trick. my only fear is that if it does, i'll start buying more moonlanders hahaha
These are sleeve bearing fans so they do need to be greased up once in a while. A bit of machine oil should do the trick. (like mentioned above you can unscrew the fan and get to the sleeve bearing by pulling back the sticker on the back of the fan.
I will also be listing fan replacement at shop.futurebit.io at my cost + shipping which will be under $5. If you want something that will last longer I would go with a dual ball bearing 25mm 5v fan which some people have listed here before. Of course these can get rather pricey.
Maybe you would consider putting the ball bearing fan on the website as an upgrade?
Thats a good idea...ill see if I can source some for cheap.
Any update on this?? Thanks!!
Once you told me i needed to see devices in "Devices and Printers" I started suspecting connection problems. I connected the USB hub to another usb 2.0 port and the Silicon Labs CP210x devices showed up. I then went and connected the hub to a different USB 3.0 port and its working there. but the original USB 3.0 port doesn't see them any more. So now i am worried about my ports. I use a powered usb hub for several reasons but I might have to find another.
