@FUTURAMA,
What country or the area are you in? If in USA or some EU area, there may have a few OEM fans available for sale.
@BitmainWarranty
I don't currently live in United States, but if you have some fans for S4 Antminer for sale, I can buy them with BTC and send them to my mailbox in miami.
I suggest submit a ticket or email asking. They are very quick/good support team. -
If they have OEM fans for sale I'm sure shipping to your Miami mailbox is not a problem.
