Blower fans blower fans i'm converting everything

I have a few hundred gpus running many water cooled etc but i run many of the gpus fan cooled and after about a year of 100% fan speed fixed the sleeve bearings dry up and as soon as you try to repair them you realize that when they dry up you can not oil them it never works right again.
So I bought Delta commercial 12v 1.2a ball bearing blower fans and epoxied them on 6 of my older RX480 4gb from january 2016 they made it a long time but 3 of them had only 1 fan working lol just diehard buggers never over heated still but was running low 80’s c and it was time.


now temps are between 69-72 dual mining very happy with the performance. I’m going to change out some others soon too.
