Asus Motherboard P8Z77-M - Manual (Page 35)

1-25 Chapter 1: Product introduction
5. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1-3)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
6. TPM connector (20-1 pin TPM)
This connector supports a Trusted Platform Module (TPM) system, which can securely
store keys, digital certificates, passwords, and data. A TPM system also helps enhance
network security, protects digital identities, and ensures platform integrity.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• CPU fan (4-pin) and CHA fans (3-pin/ 4-pin) support ASUS Fan Xpert+ feature.
• If you install two VGA cards, we recommend that you plug the rear chassis fan cable to
the motherboard connector labeled CHA_FAN1-3 for better thermal environment.
Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
TPM module is purchased separately.
