⚠️ Important for UAE Conditions (Air-Cooled)

In UAE ambient temps of 45–47°C, air-cooled miners typically draw **~15% more power**, run hotter, and face a higher monthly breakage rate. Hosting sites often use water curtains to cool inlet air, which raises humidity—many failures from humidity are not covered by warranty. Most serious UAE farms have moved to hydro or immersion for stability and safety.

Looking for a stable, quiet setup in the UAE? Explore our hydro-cooled miners (recommended).

📈 Performance Insights

Bitmain’s official testing shows stable output across different ambient temperatures:

Hashrate vs. Ambient Temp – consistent performance through standard operating range.
J/TH vs. Ambient Temp – efficiency curves referenced at 25°C inlet.
