Asus F1A55-M - Manual (Page 32)

1.10.2 Internal connectors
1. Power, CPU and chassis fan connectors (3-pin PWR_FAN, 4-pin CPU_FAN, and
4-pin CHA_FAN)
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.
• The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.
• Only the CPU_FAN and CHA_FAN1 connectors support the 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 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.
2. 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 TPM module is purchased separately!
