For enthusiasts, the options available within the BIOS can turn a good board into a great one. The ability to manipulate frequencies, voltages, and fan control settings vary depending on the hardware and the amount of trust placed in the users' hands by the manufacturer.

Frequency and voltage controls.

Fan Control options.

SmartFan Enabled
Min. Temp: 0 to 50 (30 default)
Max. Temp: 51 to 100 (70 default)

The level of frequency and voltage customization is appropriate for this type of board. Small adjustments can be made to CPU, chipset, and memory voltages. Frequency settings allow very high overclocks, but with the voltage limitations, this wide range is unnecessary.

Fan control of the board's single controllable header can be handled in two different ways. You have your choice of five different preset speeds (Quiet, 50%, Medium, 75%, or Full on) or you can enable SmartFan to fine-tune the minimum/maximum temperatures and PWM duty cycle of the fan. This is not fantastic fan control but still better than many mainstream mATX boards.
