Quadra uses temperature sensors to protect the device from excessive temperature.
Warning Temperature and Throttling
Throttling will be activated once the device composite temperature reaches or exceeds 70°C. Throttling will be deactivated once the composite temperature drops again below 70°C.
Device performance will be reduced during throttling. The following component clock speeds will be reduced during throttling
CPU
Encoder Engine
Decoder Engine
2D Engine/Scaler
Note that ni_rsrc_mon LOAD values may appear doubled or halved for a transient period after switching between throttling and non-throttling states due to pre-throttle/unthrottle load stats being measured against current clock.
Critical Temperature and Device Reset
To protect the Quadra device, if the composite temperature of 80°C or more is detected, the device will reset. This will result in a loss of all current workloads.
