Intel® Desktop Board DG41RQ Technical Product Specification

Technical Reference2.5.2 Fan Header Current CapabilityCAUTIONThe processor fan must be connected to the processor fan header, not to a chassis fanheader. Connecting the processor fan to a chassis fan header may result in onboardcomponent damage that will halt fan operation.Table 28 lists the current capability of the fan headers.Table 28. Fan Header Current CapabilityFan HeaderProcessor fanRear chassis fanMaximum Available Current2.0 A1.5 A2.5.3 Add-in Board ConsiderationsThe board is designed to provide 2 A (average) of +5 V current for each add-in board.The total +5 V current draw for add-in boards for a fully loaded board (both expansionslots filled and the PCI Express x16 connector filled) must not exceed 8 A.2.6 Thermal ConsiderationsCAUTIONFailure to ensure appropriate airflow may result in reduced performance of both theprocessor and/or voltage regulator or, in some instances, damage to the board. For alist of chassis that have been tested with Intel desktop boards please refer to thefollowing website:http://www3.intel.com/cd/channel/reseller/asmo-na/eng/tech_reference/53211.htmAll responsibility for determining the adequacy of any thermal or system designremains solely with the reader. Intel makes no warranties or representations thatmerely following the instructions presented in this document will result in a systemwith adequate thermal performance.CAUTIONEnsure that the ambient temperature does not exceed the board’s maximum operatingtemperature. Failure to do so could cause components to exceed their maximum casetemperature and malfunction. For information about the maximum operatingtemperature, see the environmental specifications in Section 2.8.57
