ANTMINER S4 Discussion and Support Thread
dmwardjr:
I had to get replacement fans for an S4. Two of them failed on me. The propellor with axel came out of it's socket on both of them [exposing the copper coils].
I decided to order some fans to have ready to replace failed fans in the future to avoid too much down time. I also bought extension cables, as the cables that come with the fans are not up to 27 inches long [Needed for the furtherest fan in the back left of the unit]. I purchased three (3) Delta Electronics PFC1212DE 120x120x38mm Cooling Fan, 252.85 CFM, 5500 RPM, 66.5 dBA, 4.8 Amp, PWM Connector. This fan comes fabricated from the manufacturer with a 4 pin connector. Here is a picture of the fan:
The following is a video review of the fan to also show watts consumed at full speed: approximately 51.2 watts at full speed (5500 RPM & 252.85 CFM).

we are sorry to hear that, it may be a time for the Control PCB unit to be replaced. Could be the control PCB itself or it could be the beagle bone or combination of both.
However, once in a very while... the MicroSD card physically goes bad. We have seen a few cases where simple MicroSD card replacement from a local store (kingstone or Sony 4GH) took care of the problem.
if another MicroSD card doesn't work, please proceed with the parts replacement via warranty. support @ bitmain . zendesk . com
Thank you

Using windows, is there software to flash the S4 image? I cant seem to find any software. I looked at windows disk imager but it only takes .img files
I tried this, it still did not work. I cant connect to it at all, but both LED are Green and the LCD screen is lit up just blank

I would say this is prone to happening, and with the S2 Ive replaced the SD card twice. Other RPI/BBB-controlled ASICs (BTCgarden, rockminer, bitfury) all have the same problem - SD cards dont always handle reboots or power 'blips' well.
