It does seem to automatically throttle the fan speed in response to temperature. It has two 4 pin PWM headers and two 3 pin headers on the board, and the bios config has options to enable fan speed control on either of the 4 pin headers. > This is strange.

I began to suspect as much. Do you know if anyone is working on a driver for it, or if the data sheet is available so I could take a crack at it? Then again, I wonder if it might be better to come up with an SSDT I can dynamically load to define the ACPI FAN and TZ objects and let the regular acpi driver manage it.
