Thermal

The R815 thermal solution includes:

Energy-efficient fans with lower power consumption per fan than previous 2U
products.

Custom air baffling directs airflow through the components to maintain proper
cooling while improved chassis ventilation ensures sufficient airflow to allow
the AMD G34 feature set to be deployed in a 2U chassis.

Custom-designed heat sinks maintain CPU and IOB chip temperatures within
thermal design targets.

Highly Optimized Fan Control Algorithm:

Base fan speeds are a function of hardware configuration and ambient
temperature to minimize airflow for a given environment.

Closed-loop PID control algorithms are used for both CPU and DIMMs to
maintain appropriate thermal margin.

Double-refresh switching allows for DIMM temperature excursions up to
95°C while maintaining performance and thermal design targets as follows:
o The R815 thermal algorithm monitors the thermal sensor on each
DIMM to maintain DIMM temperatures below the typical 85°C
specification in normal operating conditions.
o Under extreme operating conditions the thermal algorithm can
switch the DIMMs into Double-Refresh mode allowing an additional
10°C of thermal headroom. In Double-Refresh mode DIMMs are
allowed to operate as high as 95°C.
