Intel Desktop Board DG41TY Technical Product Specification

2.5.2  Fan Header Current Capability 
 CAUTION 
The processor fan must be connected to the processor fan header, not to a chassis fan 
header.  Connecting the processor fan to a chassis fan header may result in onboard 
component damage that will halt fan operation. 
Table 29 lists the current capability of the fan headers. 
Table 29.  Fan Header Current Capability 
Fan Header  Maximum Available Current 
Processor fan  2.0 A 
Front chassis fan  1.5 A 
Rear chassis fan  1.5 A 
2.5.3  Add-in Board Considerations 
The 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 (all three 
expansion slots filled and the PCI Express x16 connector filled) must not exceed 8 A. 
2.6  Thermal Considerations 
 CAUTION 
Failure to ensure appropriate airflow may result in reduced performance of both the 
processor and/or voltage regulator or, in some instances, damage to the board.  For a 
list of chassis that have been tested with Intel desktop boards please refer to the 
following website:

All responsibility for determining the adequacy of any thermal or system design 
remains solely with the reader.  Intel makes no warranties or representations that 
merely following the instructions presented in this document will result in a system 
with adequate thermal performance. 
 CAUTION 
Ensure that the ambient temperature does not exceed the board’s maximum operating 
temperature.  Failure to do so could cause components to exceed their maximum case 
temperature and malfunction.  For information about the maximum operating 
temperature, see the environmental specifications in Section 2.8.
