After reviewing the multiple threads regarding fan noise on Sager M579x (Clevo M570RU) series, sager had made additional fan firmware adjustments with Clevo and has receive the following adjusted firmware. “Version 1.00.07Sb”

How-to ID your firmware version:
Please turn on “Boot-time Diagnostic Screen:” in the system BIOS to disable the boot logo
Then review the line” KBC/EC Firmware Revision:” during the system POST screen

Standard stock firmware from Clevo: 1.00.xx
Sager Edition: 1.00.07Sa (Sager revision a) what we have released last week.
Sager Edition: 1.00.07Sb (Sager revision b) released today 1/21/2008

Fn+1: Full Fan Speed

Fn+3: Mid Fan Speed (however fan will still automatic adjust speed up to full speed if temperature reaches our preset High throttle point, and back to Mid speed when cooled down.)

Fn+2: remains as system original default to enable / disables SRS audio.

Starting today all new sager NP579x series will be shipped with this new firmware version, and PCTorque customers can request the firmware update directly with Sager Techsupport.
