Spire 9T236B1M3G Heatsink From All Angles
	The Fan: The fan is 70mm in size and located slightly within a plastic frame work. The significant point of this is that a larger fan will not fit - though a taller 70mm fan will. The fan is protected from errant wires by a wire grill and connects to a standard three pin motherboard header which supports RPM monitoring.
	Top Side: With the fan removed we find a short standoff and some cross cuts in the outer three fins of the heatsink. The metal showing on either side of the fan are the spring clips, which are pulled into place by a small level connected to each side.
	Side A: The base of this socket 478 heatsink is pretty thick - 10mm at the center, and 8mm thick towards the outer edges. The extruded aluminum fins are ~1.3mm thick and spaced 2mm apart. The fins are smooth finished, though the outer set do have some scalloping for added grip. The 16 main fins are about 33mm tall.
	Side B: Cross cuts have been made in the outer three sets of fins every 6.5mm to probably improve airflow. The clips used to grasp onto the HSRM are unique to Spire, and so far I haven't seen them used anywhere else. As the lever is pushed down, the clips are pulled up and inward to apply a constant force which should prevent the Spire EasyStream from coming loose.
	Heatsink Base: We mentioned the base before, and you can probably see why we were so impressed. Machined perfectly flat, the base is very smooth and so only a very small amount of thermal compound need be applied. Very few heatsinks have a finish of this type, and even fewer socket 478 heatsinks since they are not in direct contact with the silicon core.
