Table 29 provides maximum case temperatures for the board 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 board.

2.7 Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Telcordia SR-332,
Method I Case 1 50% electrical stress, 40 ºC ambient. The MTBF prediction is used to
estimate repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 40 ºC. The Intel Desktop Board
DG41TX MTBF is 484,154 hours.
