1) Operating Environment

Recommended Room Temperature : 15~28

Operation in comfortable room temperature is recommended.

2) Precautionary Notes on Booting

When booting the computer, it may automatically power down after an alarm sound is generated to indicate that the rotation of the CPU fan is slow by a system monitoring program. If this happens, connect the fan on the stock CPU Cooler to the 3-pin connector for the CPU Cooler on your motherboard. Boot the system and set CPU Fan Detected to Disabled in the BIOS settings. Turn the system off, remove the CPU Cooler fan, and reboot.

NOTES)

1.Some motherboards do not boot if the rotation of the CPU fan is not detected. There might not be a "CPU Fan Detected setting in the BIOS setup, but updating the BIOS could solve this problem. For more information on updating the BIOS, please refer to your motherboard manufacturer s website.

2.When using an Intel motherboard, if you remove the motherboard from an existing system and attach it to the TNN 500AF, the system s Active Monitor may generate an alarm sound with a warning that there is no CPU fan. Remove Active Monitor from Add/Remove Programs applet in Control Panel and reinstall.
