Dynatron DC1U-B02 Heatsink From All Angles
	The Fan: The squirrel cage fan is not typically used in this way, but this offers an ingenious solution to the vertical height constraints of the 1U rack mount environment. Because air is being exhausted to one side out the top, it is important to ensure that the intake is being dawn in through the fins themselves. Since there is no gasketting between the squirrel cage intake and the fan shroud it is possible that some air is taking the path of least resistance and forgoing the route through the copper fins. The fan draws power from a standard three-pin motherboard header which supports RPM monitoring.
	Heatsink Top: This hole in the fan shroud serves as the intake for the fan - air is drawn in through either side of the copper heatsinks' fins, and up through this hole. The fan is mounted on two small posts which hold it firmly in place.
	Side A: From the side you can appreciate just how small this heatsink really is. The DC1U-B02 heatsink measures just 14mm tall, with the entire package (fan and heatsink) coming in under the 30mm mark. The fan shroud is a one size fits all affair. The same components are used for the Socket A version of this cooler. The shroud is held in place with four screws and leaves about 8mm of fins exposed on either side.
	Side B: The copper base measures 4mm thick and the fins are about 0.3mm thick. Each of the 35 fins are spaced 1mm apart to ensure good airflow intake. One of the nice benefits of a skived heatsink is that the fins are so thin they pose little resistance to air. There is no solder joint since the fins and base are one and the same. Each fin measures 8mm tall.
	Heatsink Base: The base has been face milled perfectly flat, and is very smooth. Only a small amount of thermal compound should be used with a base of this finish. Too much compound would actually get stuck between the heatsink and processor heatspreader instead of filling in the few microvoids in the metal surface finish.
