The cold air fan duct that Antec uses is something that many computer builders are not used to as they were not often used before 2005. The cold air duct is used to bring in air from outside the case that is colder than the internal air to help lower case and processor temperatures. As you can see from the image below many adjustments can be made to the duct.
The duct needs to be installed in the case and adjusted from side to side first. Once this is adjusted you can adjust the height of it above the processor fan. We installed our fan duct as seen below so it was placed directly above the processor heat sink.
With that installed the internal part of our system build is completed! Let’s step back at take a closer look at our work:
The system looks good and we are ready to put the door back on and move along.
