If anyone has any objections, please let me know. ------------------ From: Armin Wolf [ Upstream commit ddb61e737f04e3c6c8299c1e00bf17a42a7f05cf ] It turns out the second fan on the Dell Precision 490 does not really support I8K_FAN_TURBO. Setting the fan state to 3 enables automatic fan control, just like on the other two fans. The reason why this was misinterpreted as turbo mode was that the second fan normally spins faster in automatic mode than in the previous fan states. Yet when in state 3, the fan speed reacts to heat exposure, exposing the automatic mode setting.
