Here is a picture of my ASUS RX480 gpu in pieces after someone stuck their finger into one of the fans spinning at 3400rpm.
They managed to break off one of the fan blades, more over i did not notice for a couple of days before the vibrations caused by the imbalanced fans made me investigate.
I searched the internet for a replacement fan which would have taken a week to arrive so i resorted to good old fashioned super glue.
The fan sitting on the black box is the one i repaired. The GPU has been working fine now for over a month and no vibrations.
I am one happy miner.
