Early signs – elevated fan RPM, hashrate variance, error codes – appear before failure. In a monitored facility, these are caught at the rack level. At ValueHash, on-site staff resolve it; operators are notified, not asked to troubleshoot remotely.

Most facilities use air cooling – controlled intake and exhaust routing designed around the hardware, not retrofitted into existing buildings. For higher-density setups, immersion cooling submerges ASICs in dielectric fluid for direct heat extraction. ValueHash offers both.

It depends on the provider. At ValueHash, yes – cooling and airflow are managed daily by on-site staff with ventilation design backgrounds, not outsourced or handled remotely. It’s part of base operations, not a separate service tier.

Thermal throttling cuts hashrate 10–30% while the miner still draws full power. At $0.07/kWh, a unit throttling 20% of operating hours loses measurable monthly output for identical electricity cost. Stable cooling protects both earnings and hardware ROI.

Manufacturers specify 5°C-40°C ambient inlet. In practice, keeping inlet air below 30°C meaningfully extends hashboard lifespan – thermal cycling near the upper limit accelerates solder fatigue even within spec. ValueHash targets 18°C-28°C across rack positions.
