Can i use the delta fan tfc1212de 3.9A on antminer S5 or the 3.9Amper its so much for S5 controller?
How else controlling this fan for only 3.000-4.000rpm and not full load at 5.500rpm?
Thank you!
no those fans wont work on S5 controllers, tried it , in fact a lot here have, some have even bricked a S5 or two because they kept pushing it .
there is a way of speed controlling them off a PSU

I'll use them one day to see how they work .
I just linked it for you as a option.
