CNPS7000-Cu Heatsink From All Angles
	The Fan: The fan Zalman use in this heatsink is 84mm in diameter for a reason. Rotating at 2400RPM allows it to move air without creating a lot of noise that a smaller fan moving the same volume of air would create. This has been an old trick of the trade for years - larger fans don't need to spin as fast to move the same volume, so there can be a significant reduction in noise. The fan connects via a standard three pin motherboard header which supports RPM monitoring. Zalman's Fanmate 1 can be used to further decrease the speed of motor for even quieter operation if desired. Decreasing the speed of the fan will impact on the heatsinks performance by a certain degree however.
	Heatsink Top: With the fan and spring clip mechanism removed we can see the CNPS7000-Cu for all it is worth. The entire heatsink works together in the name of cooling. Made from an assembly of individually punched out sheets of 0.4mm thick copper, the assembly is then squeezed together under high pressure and bolted tight. the fins of the heatsink come together to form the base of the heatsink, and the frame for the fan and clipping mechanism in an almost graceful, if not efficient manner. The central base section is ~26mm wide, and from tip to tip the heatsink measures approx. 110mm x 110mm. It looks circular, but is more oval shaped really. The cut out in the center of the base section is for the clipping mechanism which applies pressure at the center of the heatsink. This could cause problems with motherboards which have placed the m478 off center with regards to the HSRM.
	Side A: Standing 62mm high, the CNPS7000-Cu is fairly compact all things considered. Most heatsinks have the fan mounted on top of the fins which can raise the overall height of a cooler to well over 80mm. The copper fins are spaced about 1mm apart at the outside edges. The spring clipping system is mounted to the heatsink in such a way that there is no chance of play.
	Side B: From this side we can see just how the copper fins gradually come together to form the body of the heatsink itself. Compressed under high pressure the fins come into perfect contact at the base which is then machined absolutely flat and smooth. The bevel in the shape of the heatsink is so it will clear the HSRM.
	Heatsink Base: If you ever wanted to see the example of a perfect heatsink base finish look no further than the Zalman CNPS7000-Cu. Milled perfectly flat, there are no signs of machining even visible - the surface is razor flat, and just as smooth. The little aluminum blocks are used during the compression process to help apply even pressure, and for the mounting hardware to attach to. With a base finish of this calibre, only a very, very small amount of good quality thermal compound is necessary. Also note the two sets of holes in each side of the mounting clip, the inside holes are for a P4 mounting system, and the outside for Athlon64.
