Technical Reference
Table 32 provides maximum case temperatures for the Desktop Board D865PCD components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the Desktop Board D865PCD.

2.13 Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction Procedure,
The MTBF data is calculated from predicted data at 55 ºC. The Desktop Board D865PCD MTBF is 101,425 hours.
