Gigabyte AORUS RX580 4GB Fan Repair

Few weeks ago i found a 3 years old used Gigabyte AORUS RX580 4GB, but with a problematic cooling fans. The seller didn’t say anything and he was 300 km away... With no other alternatives i keep the card .
The bearings were almost gone...I was trying to find a replacements bearings or new fans but it was even harder . So i decide to make new ones from brass. The construction of bearings on the mini lathe was easy, and after one month of every day rendering is working fine ( 50 to 90 % fan speed for 4 hours /day)
