Intel Desktop Board DG41RQ Technical Product SpecificationCAUTIONEnsure that proper airflow is maintained in the processor voltage regulator circuit.Failure to do so may result in damage to the voltage regulator circuit. The processorvoltage regulator area (shown in Figure 15) can reach a temperature of up to 95 o C inan open chassis.Figure 15 shows the locations of the localized high temperature zones.ItemABCDDescriptionProcessor voltage regulator areaProcessorIntel 82G41 GMCHIntel 82801GB (ICH7)Figure 15.

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. Thermal Considerations for ComponentsComponentProcessorIntel 82G41 GMCHIntel 82801GB (ICH7)Maximum Case TemperatureFor processor case temperature, see processor datasheets andprocessor specification updates102 o C (under bias)108 o C (under bias)For information aboutRefer toProcessor datasheets and specification updates Section 1.2, page 142.7 ReliabilityThe Mean Time Between Failures (MTBF) prediction is calculated using component andsubassembly random failure rates. 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
