Table 32 provides maximum case temperatures for the Desktop Board D915GVWB 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 D915GVWB.

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, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is used to estimate
repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 55 ºC. The MTBF for the D915GVWB board
is 102,038 hours.
