Unable to revert fan control?

I'm on a dell latitude e6420, it works fine but I only have vaules 0, 2500 (very low, laptop heats quickly) and 4900 (very noisy). I played around with the settings and managed to make it 'hiccup' around 3800-4000, but now I can't get it back. Even worse, when I click "System auto", nothing happens, its still 2500 or 4900. I restarted my laptop and played further with the settings but nothing seems to work
 
Try to shut down the system, remove power cord and battery and wait a few minutes before turning it on. That should completely reset fan control.
