Hi,
First of all use coretemp for reading cpu temps directly from the cores. Second I don't think your motherboard (as most nforce430 Gigabyte based boards that I know of ) has an option for voltage so don't look around in vain.
The usual cool pc setup includes two case fans in a push-pull order with the cpu fan in the middle blowing towards the "exhaust" case fan. Just use low rpm fans since it's an htpc and u'll be fine. If still u can't get temps down the u have a crooked hs inside the cpu and there's nothing u can do about it.
