360° View - Sunbeamtech Core-Contact Freezer Heatsink Information on Frostytech's test methodology is available here.
The 120mm fan on the Core-Contact Freezer heatsink spins at 2000RPM by default. An optional fan speed controller can drop that down to 1000RPM if quieter operation is desired. A standard 3-pin motherboard header provides power. Note the AMD K8-style mounting clip attached to the aluminum base block, this one clip allows tool-free attaching to both Intel and AMD processors.
The Core-Contact Freezer stands 153mm tall. Its raw aluminum fins are press-fit over the four 8mm diameter copper heat pipes which rise up from the base. The bottom fin is elevated 36mm for adequate motherboard component clearance. The aluminum fins measure 0.3mm thick and are spaced 2.0mm apart. The aluminum/heatpipe base is 10.5mm thick.
The base of the Sunbeamtech Core-Contact Freezer has a machined surface finish, done with a slight ridge texture. The portion of the base that comes in contact with the CPU measures 45x38mm, about 7.75mm (x4) of that is pure copper heatpipe. Looking at the top of the Core-Contact Freezer we see the tips of all four 8mm diameter U-shaped copper heatpipes. The aluminum fins are roughly 125 x 75mm in size, and the trailing edge has a slight bend to direct airflow down towards motherboard components.
