Intel Desktop Board DQ35JO Technical Product Specification Table 29. Thermal Considerations for Components Component Maximum Case Temperature Processor For processor case temperature, see processor datasheets and processor specification updates Intel 82Q35 GMCH Intel 82801IDO ICH9DO 97 oC (under bias) 92 oC (under bias) For information about Processor datasheets and specification updates Refer to Section 1.2, page 15 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 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 Desktop Board DQ35JO MTBF is 207,844 hours. 2.8 Environmental Table 30 lists the environmental specifications for the board. Table 30.
