Title: Antminer Fans !!! - Are these EXACTLY the same or am i missing something ??
Post by: bilabonic on January 13, 2017, 11:59:01 AM
Hi All

Looking for replacement S7 fan and had a quick search on Ebay and came across two fans, one for an S4, one for an S7....

Different prices, same seller and EXACTLY the same specs ???

Have you used these, would they run at 6000 RPM and pull a full 2.6a if required ?

Or would the PWN output control them to 4500 RPM /1.8A ??

No CFM rating either, excellent price though !!!

Yes. I am using these in all push pull set ups and yes they use the full 2.6A when required.

You can check Delta website for the specs. CFM as I remember is 191.

Cheers.
