You need to give more details if you expect any meaningful help. There are several fans in your computer depending on configuration. If you let us know which fan you want to control, then that'll make it a whole lot easier to give you a detailed response.
Generally speaking however, AWCC can be used to control fan curves for the intake fan as well as the radiator exhaust fan or CPU fan (if air-cooled). Something like MSI Afterburner can be used to control fan speeds on Nvidia graphic cards.
