Intel® Desktop Board DG41RQ Technical Product Specification

Technical ReferenceTable 29 provides maximum case temperatures for the board components that aresensitive to thermal changes. The operating temperature, current load, or operatingfrequency could affect case temperatures. Maximum case temperatures are importantwhen considering proper airflow to cool the board.Table 29.

The calculation is based on the Bellcore ReliabilityPrediction Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBFprediction is used to estimate repair rates and spare parts requirements.The MTBF data is calculated from predicted data at 55 ºC. The Intel Desktop BoardDG41RQ MTBF is 106,946.1 hours.59
