A modern ASIC is compact industrial hardware: multiple fans, several kilowatts and continuous airflow. Plan the environment before attempting noise reduction.
High-speed fans move air through dense heatsinks. Nominal figures around 70–80 dBA are common for industrial miners, while actual sound depends on model, ambient temperature and fan speed.
A single dBA value does not fully describe disturbance: frequency, distance, reflections and miner count matter.

A 3 kW ASIC releases roughly 3 kW of heat into its surroundings, about 10,236 BTU/h.
This relationship lets you estimate exhaust or cooling needs before the miner is running.
Prevent exhaust air from returning to the miner intake. Separate cold and hot paths where practical and avoid restrictive ducts that increase pressure and fan noise.
With multiple miners, plan total airflow and total heat, not only one unit at a time.
Enclosures, ducts and silencers can reduce transmitted noise, but restricting airflow can increase temperatures and reduce stability.
Monitor temperatures, fan speed and hashrate after any airflow modification.
