Finally, I managed to update the BIOS but fan control only provides 2 options: "continuos" and "automatics". I didn't even notice the difference. None of them works.
In the BIOS there is no possibility to set voltage or Pwm. Could I set these parameters in a software like speedfan?
If I set "continuos", will I have the possibility via speedfan or similar software to manage the fan in order to let it start at full voltage?
I asked you these questions because I wish to avoid useless trials, as my motherboard is now disconnected and I should lose time to reassemble hardware and case. And then? Realizing that speedfan or similar is unable to better manage fan control?
