Bitmain Antminer E11 (9.5GH)

The Bitmain Antminer E11 (9.5 GH/s) presents itself as a purpose-built ASIC for the EtHash algorithm, optimized principally for Ethereum Classic and other EtHash-based coins, delivering a sustained hashrate of 9.5 GH/s at a power draw of 2,470 W and an energy efficiency of 0.26 J/MH; engineered with industrial reliability, its compact 400 x 195 x 290 mm chassis and 14.2 kg mass house a thermal regime of four high-speed fans and smart airflow channels to maintain stable temperatures during continuous operation, producing about 75 dB of acoustic output that positions it for data-center or dedicated mining-room use rather than quiet residential spaces; installation is straightforward - a single Ethernet connection and a standard 240 V supply are sufficient to bring the unit online, and it integrates with common EtHash pools and monitoring tools, while routine maintenance is simplified by its accessible layout and emphasis on robust components; for best results deploy it in well-ventilated racks with reliable network and power infrastructure, allow for adequate exhaust and intake clearances, monitor firmware and fan behavior through the device’s management interface, and plan for ambient operating conditions and humidity control to maximize uptime and longevity - the E11 thus reads as a precise, industrial instrument that converts electrical energy into ordered computational work, its steady mechanical respiration revealing the practical limits and opportunities of large-scale EtHash mining.

I can write in a similar strategic-analytical voice that blends technical rigor with a sense of appetite and impending risk. Treat the Antminer E11 as a compact industrial predator: its steady output is 9.5 GH/s and its electrical appetite is 2470 W. Its energy metric of 0.26 J/MH maps electricity into coin at mechanical efficiency. The chassis measures 400 x 195 x 290 mm and weighs 14.2 kg, so plan rack density accordingly. Four high-speed fans drive cooling and keep core temperatures stable during continuous hashing. Acoustic emission sits near 75 dB, so locate units in dedicated rooms or facilities with acoustic mitigation. Network integration needs only an Ethernet port, and the miner runs on a standard 240 V supply for simple plug-and-play deployment. Operate in ambient temperatures from 5 to 45 °C and humidity between 5 and 95% to avoid thermal stress or corrosion. Expect continuous maintenance cycles: inspect and clean fans and air paths regularly, monitor firmware and hash rates, and replace failed fans promptly to prevent downtime. For risk management, provide redundant power feeds, surge protection, and UPS coverage for critical clusters to reduce catastrophic outages. Cooling design matters more than raw hashrate; efficient airflow and heat rejection lower operating cost and extend hardware life. Consider grouping machines to harvest waste heat for facility heating or to consolidate cooling infrastructure for better overall efficiency. Choose mining pools and payout strategies that align with electricity cost models and tax regimes to protect margins. Track fan RPM, board temperatures, and hashrate trends with automated alerts to catch degradation early. In short, the E11 converts significant electrical power into predictable EtHash throughput, and the true levers of profitability are power cost, thermal engineering, maintenance discipline, and operational contingency planning rather than raw singular performance.

Etchash is a cryptographic hash function that serves as the backbone of Ethereum Classic proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
