|| Experts Tip: Enable
SmartFan in the BIOS|
Foxconn's Fox One software fan controller works pretty well when set to manual mode, but SmartFan mode will not function unless it's also enabled in the BIOS.
To ensure that SmartFan is working, press the Del key at system POST and go to the PC Health Status section in the BIOS. There you will find the SmartFan options. All you need to do is make sure it's set to 'PWM mode'. If that is the case, SmartFan will automatically adjust the heatsink fan according to the values you set. The stock Intel LGA775 heatsink uses a PWM fan, after market heatsinks may not.
You can differentiate a PWM fan from the standard
variety by the 4-pin fan power cable. Standard 12V DC computer fans will use either 2-pin or 3-pin fan power cables. The 3-pin connector is by far the most common as the third pin acts as an RPM sensor. In the above photo, the 4-pin PWM connector is at the far right bottom corner. This 4-pin motherboard CPU fan header is backwards compatible with the 3-pin fan variety, but the extra controls PWM fans bring to the table are specific to that class of fan.

Foxconn Overclocking Tests
Foxconn has a pretty good reputation with us when it comes to overclocking, so let's dive into this with some big expectations for the 975X7AA-8EKRS2H motherboard and see where it takes us. Starting at 200 MHz, the FSB will be increased in 5 MHz intervals.
Overclocking commenced at 200MHz, and in no time the system was at 221 MHz and starting to show some signs of instability. This turned out to be the processor flaking out, not the motherboard, and was resolved by increasing the CPU voltage to 1.35V.
By the end of our overclocking session, the Foxconn
975X7AA-8EKRS2H motherboard had reached a maximum speed of 255 MHz (I expect it
is the processor holding the motherboard back). An overclock to 255
MHz is what we have seen from a couple other motherboards we've tested with this
Pentium D 840. With a 1066 MHz Intel Extreme Edition processor there is a good likelyhood that the Foxconn 975X7AA-8EKRS2H might go further. In any case, it's not bad considering the Pentium D 840 is running at 4.08 GHz (with a voltage of 1.45V) with nothing more than a stock heatsink.
