Ventilation Fans for Crypto Mining Farms
ASIC miners turn almost all of their electrical power into heat. A room or container full of miners produces a large, constant heat load, and the miners’ own fans need a supply of cool air and a clear path for hot exhaust. If hot air recirculates, hashboards throttle or shut down. Large exhaust fans that remove hot air quickly, with filtered intake air, keep the site running.
LONGWELL supplies high-volume axial exhaust fans, sidewall fans and EC fans for mining farms, mining containers and hosting facilities, through contractors and integrators.
Typical layouts
| Site type | Air path | Fan choice |
|---|---|---|
| Warehouse mining farm | Cold intake wall → miner racks → enclosed hot aisle → exhaust wall or roof | Large axial or sidewall exhaust fans in the hot-aisle wall |
| Mining container | Filtered intake on one side, miners in rows, exhaust fans on the opposite side | Axial or EC exhaust fans sized to the container’s power |
| Small room / home mining | Ducted exhaust from the miners to outside | Inline or mixed-flow duct fans |
How to size exhaust fans
1. Start from the power
Nearly all miner power becomes heat. Required airflow (m³/h) ≈ 3.1 × heat load (W) ÷ allowed temperature rise (K) between intake and exhaust.
2. Allow for the miners’ fans
Room or container fans should move at least as much air as the miners exhaust, so hot air does not build up in the hot aisle.
3. Intake and filtration
Give the intake enough area with filters or screens against dust and insects, and keep it away from the exhaust to prevent recirculation.
4. Redundancy and control
Use several fans rather than one, so a single failure does not stop the site. EC fans with 0–10 V or PWM control can follow the temperature, reducing power and noise at night or in winter.
5. Noise
Mining sites are often close to neighbours. Larger, slower fans and acoustic treatment help.

FAQ
How much airflow does a mining farm need?
Required airflow (m³/h) ≈ 3.1 × total miner power (W) ÷ allowed temperature rise (K). For example, 100 kW with a 15 K rise needs roughly 20,700 m³/h, before margin.
Exhaust fans or supply fans?
Exhaust from an enclosed hot aisle is most common, because it removes hot air directly and keeps the intake side cool.
Can EC fans reduce running costs?
EC fans can slow down when less cooling is needed, such as at night or in winter, which reduces fan power. Savings depend on the site.
Do you supply fans for mining containers?
Yes. Axial and EC fans are supplied to container builders; send the container power and layout for a selection.
