Hi Fellow miners!
My very first Mini-Doge miner, in service since NOV 18th 2021 has a bad fan - bearing issue/ loud grinding sound.
What size are these fans and does anyone have a good Amazon link for replacements?
Thank you

Many of these cheap 4 inch fans for power supplies and such have bushings, not bearings. As such they need some good oil to work and many fail in a few months to a year. The fix is using good machine oil.
If you can get the fan out usually these 4” fans have a sticker covering the bushing. Carefully pull back the sticker and put 2-3 drops of good machine oil onto the bushing then push the sticker back down. You’ll be good for a year or more.
