You can connect up to 8 fans to Asus Commando mainboard:

The fan works pretty quietly, you don’t need to reduce its rotation speed at all and it can receive power from the PWR_FAN connector without the rotation speed control option. The rotation speed of the processor cooler and three other fans connected to CHA_FAN1, 2 and 3 can be managed using Q-Fan function. The remaining three OPT_FAN connectors are also sophisticated enough:

Next to each of them there are connectors for thermal sensors (that should be purchased separately). You may even make the fan rotation speed vary depending on the reading from the corresponding thermal sensors.

Now that we have move down to the lower edge of the PCB let’s take a closer look at the area around the chipset South Bridge. The first thing that catches your eye is the three convenient buttons intended for Powering On, Resetting and Clearing CMOS. The latter is protected against accidental hitting with a jumper. All three buttons are lit when the system is running. As you can see, these are real buttons, and not some barely noticeable dots or pins, which we have often seen on other mainboards.

However, we didn’t have to use the Clear CMOS button even once, because the C.P.R. (CPU Parameter Recall) technology works ideally activating immediately after the first failure and restarting the system with guaranteed operational parameter settings.

All Serial ATA connectors are placed into a single vertical stand, which saves a lot of space on the PCB and makes connection real easy. I would also like to stress the pretty traditional location of the FDD connector, 24-pin power supply connector and the IDE connector positioned “sideways”, which, however, are extremely convenient for the contemporary mainboards.

On the back panel of the mainboard there are no COM or LPT ports, however, there is a LED indicator reporting the POST codes on system boot-up and later displaying time.

The mainboard back panel also carries the following connectors and ports:

• PS/s keyboard connector;
• PS/2 mouse connector;
• IEEE1394a;
• 2 network RJ45 connectors;
• 4 USB ports;
• Coaxial and optical S/PDIF.

All other audio connectors have been moved to a separate SupremeFX daughter card that fits into a special slot on the mainboard PCB.

Since we mentioned the expansion slots, we should say that there are four (!) PCI slots and two PCI-E x16 slots on this mainboard, one of which working in x4 mode.
