Temperature, fans, and power
Controlling fans and power requires full agent permissions.
In read-only mode, monitoring is available. The settings are on the Tuning tab.
Fan modes
Section titled “Fan modes”Driver
Section titled “Driver”The GPU driver regulates the speed. On supported cards, the fans can stop at a low temperature. Check the memory temperature separately: the normal mode depends on the card model.
Fixed speed
Section titled “Fixed speed”Set the speed as a percentage. It does not depend on load or temperature. The minimum supported value depends on the GPU; the panel shows the limit.
Target temperature
Section titled “Target temperature”Set a temperature and a sensor. The agent regulates the fan speed based on its readings. This mode lets cooling change together with the load.
| Sensor | What is counted |
|---|---|
| Hottest | the hottest of the available sensors |
| Core | GPU core temperature |
| Memory | video memory temperature, if the sensor is available |
If the selected sensor is unavailable, the hottest of the available sensors is used. Core and memory temperatures can differ significantly; there is no universal correction between them.
Power limit
Section titled “Power limit”The limit is set in watts and applied to all GPUs on the server. Lowering the limit can reduce power draw and heat but also reduce performance. The result depends on the GPU and the load.
Before confirmation, the panel shows the difference from the current limit and an estimate of electricity costs.
The panel does not allow setting a common limit if the GPUs have not reported a valid power range or the cards’ ranges differ. Individual limits for separate GPUs are unavailable.
How to check the result
Section titled “How to check the result”On the Activity tab, check the command result. Then open Overview: power draw updates with the next measurements, and temperature changes gradually. Compare readings under comparable load.
