The Falcon IV (JYC 8A03A) makes use of four 6mm diameter copper heatpipes to conduct heat from the copper base plate to copper cooling fins above. On top of the heatsink base is a small skived aluminum heatsink, which is rather odd since the large aluminum fins (the primary air heat exchanger) should be doing much of the work. Since exhaust airflow is directed down towards this area anyway, Cooljag use this spare airflow to further reduce temperatures.

The entire fin stack of the Falcon IV (JYC 8A03A) heatsink is angled 30 degrees. This puts the bulk of the heatsink within about 25mm of the top of the CPU. Really though, the 92mm fan should be operated at full speed 100% of the time with this heatsink. At the lowest speed setting it is just not sufficiently powerful to move a satisfactory amount of air through the deep aluminum fins used on the Falcon IV.

Brackets for Intel and AMD Processors

The Cooljag Falcon IV (JYC 8A03A) heatsink ships with two sets of mounting brackets; one for AMD socket 939/AM2/AM3 processors and one for Intel socket 775/1366 CPUs. The two different metal brackets attach to the heatsink itself. For Intel users a rear-motherboard support bracket will need to be installed as well.

AMD users will be able to install the Cooljag Falcon IV (JYC 8A03A) heatsink without removing the motherboard from the case. One nice part included with the heatsink is a plastic spatula for spreading an even coat of silicon thermal compound.
