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.

Anyone having interesting fan replacement experience - please share.

Lessons Learnt:

70% of my AMD farm is RX470s - Sapphires and Gigabytes.

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.
