looking for advice on cooling setup for mining container

Finding local experts for this stuff is tough, so I'm reaching out here. I've got a 40 high cube mining container (12.024 m X 2.350 m X 2.697 m) that needs to hold up to 250 WhatsMiner M30s. Each miner has an airflow of 9.187 m³/min, and I believe the max air volume for the whole setup is 350 CFM. They suggested using 14 industrial fans on the hot side, each with an airflow of 13000 m³/h, and putting G4 filters on the cold side. Does that sound like a solid plan? Also, can we skip the fans on the cold side for air inflow? Could someone help me figure out how to calculate the necessary airflow for the container? And what about the air outflow compared to inflow? My math is pretty basic, but I think I messed up: 9.187 * 60 * 250 = 137805 m³/h Total airflow for 250 miners. 14 fans * 13000 m³/h = 182000 m³/h total airflow for the entire container. I guess I need to take the container's dimensions into account too any tips?

Im an engineer but not an expert in your specific case   I would do this calculation based on the heat dissipation of each miner. For simplyness I would equate the electrical power of each miner with thermal power. So for example if you have 250units and each unit generate 1kw, then you have to move 250kW of heat power out of your container. So you wanna know the required airflow in a worst case scenario. Worst case scenario is always during summer time. The Delta Temp between the miner and the fresh air from outside should be a criteria. I assume 30°C fresh air temperature. If the miners should not reach for example 50°C, then you have a delta Temperature of 20°C. Then have a look at this diagram. Its used for finding air flow if you install a compressor cooling like in an ice cream parlor. So for 1kW and Delta 20°C you need about 175m³/h, multiplied with 250 = 43750m³/h Edit this example to your needs... I dont know how hot the miners will be and what is your maximum fresh air temperature. If you calculate this for Delta 5°C you need about 150.000m³/h Cheers
