The fan curve is displayed as a table with the following columns:

```text
rpm1: speed in rpm for fan1 at this point
rpm2: speed in rpm for fan1 at this point
u(speed_of_unit): unit for the speed (1- Percentage, 2-PWM, 3-RPM)
speed1[u]: speed in rpm divided by 100 for fan1 at this point
speed2[u]: speed in rpm divided by 100 for fan2 at this point
speed1[pwm]: speed in pwm (0-255) for fan1 at this point
speed2[pwm]: speed in pwm (0-255) for fan2 at this point
acceleration: acceleration time (higher = slower)
deceleration: deceleration time (higher = slower)
cpu_min_temp: CPU temperature must go below this before leaving this point
cpu_max_temp: if CPU temperature is above this value, go to next point
gpu_min_temp: GPU temp must go below this before leaving this level
gpu_max_temp: if GPU temperature is above this value, go to next point
ic_min_temp: IC temp must go below this before leaving this level
ic_max_temp: if IC temperature above this value, go to next point
ic_max_temp: if IC temperature above this value, go to next point
All temperatures are in degree Celsius.
127 is the max temperature
```

**Note**: This is just a debug output. The fan curve is configured as usual using the standard `hwmon` interface.

**If you want to reset your fan curve, just toggle with Ctrl+Q or Fn+Q the power mode or restart and everything is gone.**
