1: L3+ Litecoin mining machine uses the latest generation chip BM1485 independently developed by Bitmain 2: TSMCs 28-nanometer FinFET process, and uses a fully customized design solution to pursue a more efficient and low-energy mining experience. The energy consumption ratio has reached 1.6J/MH 3: Double front and rear fans, independent heat sink, better heat dissipation 4:The chassis is made of aluminum alloy, and the surroundings are integrally formed. Each chip has an independent heat sink, and the overall structure is more compact 5:The heat sink adopts a new bonding technology to make the body more robust 6.Please note: this machine is Refurbished one, it's really like new, good working condition
