X7DCL-3/X7DCL-i User's Manual

Fan Headers

The X7DCL-3/X7DCL-i has four chassis/ system fan headers (Fan3 to Fan6), and two CPU Fans (Fans 1/2). All these fans are 4-pin fans. However, Pins 1-3 of the fan headers are backward compatible with the traditional 3-pin fans. See the table on the right for pin definitions. Note: The onboard fan speeds are controlled by Thermal Man- agement via BIOS Hardware Monitoring in the Advanced Setting. (The default setting is Disabled.) Please use all 3-pin fans or all 4-pin fans on the motherboard.

Chassis Intrusion

A Chassis Intrusion header is located at JL1 on the motherboard. Attach an appro- priate cable from the chassis to inform you of a chassis intrusion when the chassis is opened.
