Heatmaps
Heatmaps provide visual temperature and performance monitoring for mining equipment, enabling operators to quickly identify thermal hotspots, cooling inefficiencies, and underperforming units. This feature is essential for maintaining optimal operating conditions and preventing hardware damage.
For system architecture and how temperature data is collected, see Architecture — Data Flow.
Accessing Heatmaps
Navigate to a Container page (see Bitdeer Container or Antspace Hydro for examples)
Select the Heatmap tab to view temperature and hashrate data
Miner Color Indicators
The heatmap uses a dual-color system to convey both power mode and thermal status simultaneously.
Fill Color Gradient
Temperature or hashrate value
See scale below
Temperature Color Scale
Red
Highest temperature — potential overheating risk
Orange/Yellow
Elevated temperature — monitor closely
Green
Normal operating range
Blue
Lowest temperature — cooler states
For temperature alert thresholds and visual alerts by container type, see the Alerts Manual. For manufacturer-specified operating temperatures, see Supported Devices.
Temperature Metrics
MiningOS tracks three temperature measurement points for comprehensive thermal monitoring.
Inlet Temperature
The external cooling temperature provided to each miner, representing the effectiveness of the container's cooling system.
Hover over any miner to view its exact inlet temperature in real-time.
Hashboard (PCB) Temperature
The temperature of the Printed Circuit Board (PCB), critical for monitoring miner stability. Electronic components generate heat during operation, and excessive PCB temperatures can degrade performance and reduce component lifespan.
Hover over any miner to view its PCB temperature.
Chip Temperature
The operating temperature of the ASIC semiconductor chips inside each miner. Chip temperature directly affects mining efficiency and hardware longevity — operating within manufacturer specifications is essential for reliable performance.
Hover over any miner to view its chip temperature.
For manufacturer-specific temperature specifications and operating ranges, refer to:
Hashrate Metric
The Hashrate tab displays the processing power of each miner using the same grid layout.
Hashrate Color Scale
Red
Highest hashrate — peak performance
Green/Yellow
Normal hashrate range
Blue
Lowest hashrate — potential issues
Hover over any miner to view its precise hashrate value.
When a miner's hashrate is 0, its temperature is excluded from the PDU Layout views (Inlet temp, Hashboard temp, Chip temp). This prevents non-operating miners with much lower temperatures from skewing the color scale and making active miners appear falsely critical (red).
