The following table lists the minimum unimpeded airflow in linear feet per minute (LFM)
required across the processor for operations at the specified ambient temperature at sea level.
A Note on Thermal Specifications
RadiSys validates the operating specifications of its products by testing with the “hottest”
available hardware and software configuration to maximize the power supply draw and
generate a worst-case scenario. Despite these efforts, the specifications outlined above are
only benchmarks and should be regarded as such.
