TA890FXE Fan settings in bios

My current rig is a Biostar 890FXE motherboard, Phenom II 965 c2 140W, Corsair H50 water Cooler, Antec True Power 750 W power supply, Xigmatek Utgard Case, Radeon 5770 Videocard, 8 gigabytes of Corsair Gaming DDR memory at 1600. I have my cpu overclocked to 3.7 Ghz on stock voltage.

My question is I want my rig to be as quite as possible until I game, do some encoding, etc. This is where all the PWM stuff comes in. The bios has these options

Smart Fan Calibration -
Control Mode - Quiet/Performance/Manual
Fan Ctrl Off-
Fan Ctrl On -
Fan Ctrl Start Value -
Fan Ctrl Sensitive - 1-127 value (smart fan calib detects pwm value for fan as 255)

I pretty much want my pump on 100% I do have system1 fan mode setting to full on mode, but I want the fan on the radiator to start working at around 40 degrees (around a couple hundred rpms) and gradually go to 100% once it reaches right before its critical temps of 62 degrees (1700 rpm)? How do I do that with those settings, I understand the first two, but the last two confuse me??? I believe around 800-1000 rpm it wouldn't be as noisy, I would like to keep it at this range until the high fifties then go to 1700 when it reaches 60.

I don't even know if you can get that precise in the bios man...
I wish I could help...as far as I know you could just enable auto fan speed contol and set the sesetivity...i don't think you can make a curve though...
