Sensors on the RSP2 (for example) monitor the inlet and internal chassis air temperatures. If the air temperature at either of the sensors exceeds a desired threshold, an environmental monitor displays warning messages and can interrupt system operation to protect the system components from possible damage from excessive heat or electrical current.
The power supplies have their own fans. An air dam between the power supply bays and the processor module compartment keeps the airflow constant.
