||The Heatsink Fan: |
Looking at the top of the heatsink we can see the tips of
the four 6mm diameter copper heatpipes poking through. The 38 nickel plated
aluminum fins are each roughly 95 x 58mm in size, and that adds
up to a significant cooling surface area. The tabs on
either edge are for the wire fan clips to lock into.
The entire Noctua NH-U9 heatsink stands 128mm high, with each of the 38
aluminum fins measuring 0.5mm thick. Fin
spacing is 2.0mm, as this allows slower RPM fans to be used as there is
less airflow resistance. The notches along the edges of the fins in this perspective
allow 92mm or 80mm fans to fit in snugly. The 8mm thick copper base is
shown without any of the processor specific mounting hardware installed.
Heatsink Side A:
The widely spaced nickel plated aluminum fins are all
soldered to the four copper heat pipes which rise up from the base. There are no
specific instructions for orienting the Noctua NH-U9 in a specific way, other than setting
the fan to blow hot air towards the rear of the case.
The useable area of the copper base is 35 x 49mm, just
shy of the AMD Athlon64's 37.5 x 37.5mm integrated heat spreader
dimensions... The copper surface has been face milled flat, with surface
roughness in the 32 microinches area. A small tube of white silicon thermal
compound is included in the heatsink package.
