Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide

Power Connectors

The desktop boards have three power connectors. See Figure 25 on page 49 and Figure 26 on page 50 for the location of the power connectors.

Fan Connectors

The desktop boards have a 4-pin processor fan header.

Desktop boards D915GAV and D915GEV have three chassis fan headers. Desktop boards D915GAG and D915GUX have two chassis fan headers. See Figure 24 on page 48 for the location of the fan headers.

Fan Speed Control (Intel® Precision Cooling Technology)

Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor thermal diode temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds.

NOTE

Not all chassis fan headers on desktop boards D915GEV and D915GAV are controlled. Refer to Table 3 on page 13 to identify controlled chassis fan headers.

The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel® boxed processors. Disabling the chassis fan speed control results in chassis fans always operating at full speed. The chassis fan speed control feature should be disabled if a self-controlled chassis fan is attached to any controlled chassis fan header.

The overall system noise reduction will vary based on system configuration and environment.

Suspend to RAM (Instantly Available PC Technology)

CAUTION

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

CAUTION

Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.
