BTW....
.... I have several GPUs with bad fans (after abused for 24x7x365 at 100%).
.... I rather have 100% rpm fans with a few more fraction of watts and let them work to death, then a busted GPU.
I got replacement fans 2 x fans for 17$ (for Zotac 1070 Minis) from my China contacts.

These GPUs are workhorses of miners circa 2016-2017 and non-ball-bearing fans are expected to save costs.
Sapphires, EVGA, Zotac has low count of bad fans.
Worst = Gigabyte (the Auros however are doing fine).
If I could turn back time, avoid lower end Gigabytes GPUs.
Those are some expensive fans. Some cheap ones on taobao:
