Frequently Asked Questions
Q: Is this cooling fan compatible with both the Antminer S7 and S9?
A: Yes. This 120mm DC 12V brushless replacement fan is designed to be a direct plug-and-play replacement for both the Antminer S7 and Antminer S9. The 4-pin / 4-line connector matches the stock fan interface on these miners, making installation quick and hassle-free.
Q: How long will this Antminer cooling fan last?
A: This fan is rated for approximately 80,000 hours of continuous operation at an ambient temperature of 25°C, thanks to its high-precision dual ball bearing design. The flame-retardant PBT + 30% glass fiber frame further contributes to its durability in demanding mining environments.
Q: What is the noise level of this 7500RPM fan?
A: At full speed (7,500 RPM), this fan operates at approximately 64 dBA. Like all high-performance mining fans running at this RPM range, some operational noise is expected — this is normal for fans delivering 280.38 CFM of airflow at the speeds required to keep Antminer hardware cool.
Q: What direction does the fan blade rotate?
A: The fan rotates counterclockwise when viewed from the blade/intake side. This matches the original Antminer S7/S9 fan orientation for correct airflow direction through the miner chassis.
