Documentation and Accessories
The Rosewill unit came with a well written manual and an easy to follow product warranty statement.
Above is the included hardware for an AMD AM2 system. Note that if your motherboard already has an AM2 backplate on the motherboard you can install the Rosewill RCX-Z4 without removing the motherboard from the case.
The Intel and AMD Socket 939/940 installation will require you to remove your motherboard. It is also nice to see Rosewill including spare hardware in case a small piece is lost.
Rosewill also included a rheostat to control the fan speed from outside of your case.
As you can see from this image the Rosewill rheostat is more than just a simple knob, they have included additional electronics in the unit.
Here we see the included wiring for attaching the rheostat to the fan and motherboard/power source.
