Its job is straightforward: direct and channel airflow from the miner’s built-in fans into a duct system, external fan, or ventilation pathway. This guide explores the best cooling methods, from air ventilation to liquid cooling, helping you optimize performance while avoiding overheating risks. Prevents small parts from entering the fan / miner. Bitcoin mining is a competitive business. Most of the miners such as Ebit E9, Antminer S9, A3, and D3 use a 120mm cooling fan for heat dissipation, and the speed of the fan can reach Above 6000 RPM. Use External Fans Adding extra fans can significantly lower your miner’s . This is not an approximation — it is the first law of thermodynamics. Ventilation grille in black for 120 mm fans.
