Using the Cross Flow Fan

Installing the fan unit into the casing is quite straightforward as all you need to do is align the mounting holes along with those provided on the chassis. Then, use the four screws provided with the fan and you're done. If you're unsure of the fan's orientation, it's helpful to first power it up and take note of the fan's air intake and outlet ports.

The power connector on the fan unit is based on the usual three-pin power connector that can be plugged directly into any of the motherboard's fan header. Since the fan draws 12V and only 0.24A, it won't be too much for most motherboards to handle. The only drawback with this arrangement is the lack of fan speed control; it would be a different story if your motherboard's fan headers could be controlled separately.

Although noise does not seem to be of major concern, Cooler Master bundled a PCI bracket with a fan speed switch built into it. Connecting the Cross Flow Fan unit to this bracket, you can have the flexibility of four different selections; either turn it off, or select any one of the three preset speed settings (low, medium and high). Though this is an option for power users, we doubt that it's going to be of much use since one would need to flip the switch from the back of the chassis, and not via a front panel. We would recommend users to just skip this mode of control and plug it directly into the motherboard since noise generated by the fan is actually quite minimal.

The fan control switch lets you turn the fan off, or switch it to three different preset speeds (low, middle and high).

The fan speed circuitry consists of only a wire-wound resistor and a 22µF capacitor.

For those concerned about dust accumulation, we're glad to say that this fan unit can be easily disassembled for cleaning. All you need to do is to remove two screws on the motor unit and the entire fan assembly could be taken out. The fan blades can also be separated from the motor easily, just by simply pulling it out of the soft rubber socket. Once taken out, you can wash the entire fan blade drum with solvent or vaccuum it to your heart's content.

The entire fan and motor assembly can be removed by removing two screws.

The spacing of the fan blades are about three to four centimeters apart.
