As I am running the Antminer S9’s longer, I am concerned about finding a source for repair parts. When I was cleaning one of the Antminer S7’s a fan blade snapped off, and something like that might happen with the Antminer S9’s.
Already one hashing board on one of the boxes looks like it is not working, so I need to make sure to identify the following:
- Replacement fans
- Fan wire connectors
- Hashing board connectors.
Figuring I can cut and solder the fan connector, I really need to find a fan. There are lots of knowledgeable people on Bitcointalk, and I found a conversation thread that helped figure out the part number of the Antminer 6000 RPM fan. The S9 uses two of those.
The fan is a Delta QFR1212GHE-SP01, and it can be purchased from Digikey.
On the website, it says it is obsolete, although they have stock of over 1100. So I called and tried to find a replacement part. I wanted it to be the same size, but faster if possible.
The tech was very helpful and recommended the Delta PFR1212UHE-SP00. It is 6600 RPM instead of 6000, does higher CFM at 220 vs. 210, but pulls more power – 32W instead of 22W. There are only 12 in stock, but it is not an obsolete item, so it would be possible to get more.
I ordered one of each. I’ll try the higher CFM fan in one of the devices and see how it goes.
I could not get either fan to work on an Antminer S9 or S7. Not sure if it’s wired differently or what. I ended up ordering a replacement fan from Bitmain in China. That worked. The link for that part number is here:
