These are great Antminer S3 and Antminer S4 replacement fans:
Delta ABF1212LE 2000-RPM 71-CFM 1.7-Watts .14-Amps
Delta ABF1212ME 2500-RPB 92-CFM 3.2-Watts .27-Amps
Delta ABF1212HE 3000-RPM 102-CFM 4.2-Watts .35-Amps
Delta ABF1212HHE 3500-RPM 130-CFM 6.2-Watts .51-Amps
Delta ABF1212VHE 4000-RPM 148-CFM 8.2-Watts .68-Amps
The original specs call for 120mm x 38mm, 8 volt, (27.6/4)=6.9-Watts, with 238-CFM, and 4300(+-)10% RPM.
I used the AFB1212HE for quieter and better power efficiency.
Both front fans had come loose and would rub the stopping the fan causing the hashing to quit.
hello,
my s4 fan stop. i need to replace it.where can i buy it? or what is the part number of it?
regards,
