Intro
Cooling computer components with cool air passing through their heatsinks has been
around for a long time. It is effective but usually rather noisy way on keeping things
cool. This is partly why watercooling has become so popular.
It is great to see that the manufacturers have not abandoned the air coolers. There
are a lot of users that are not willing to take a move towards the wet stuff. This
time we will introduce one interesting looking heatsink that utilizes moving air
to cool itself down.

Noctua NH-U12 and Coolink U8-120-1600

Packages
Product from both of these manufacturers utilize the same heatsink that they developed together.
Only thing separaing these two units from one another is the fan that is bundled with the Coolink
package. Coolink do have the same package in their product lineup without the fan (U8-120),
making it identical with the Noctua one.

Content
From the package we can find mounting parts for Intel P4 478, LGA 775 and AMD K8 processors.
In Coolink bundle we also find the fan and the potentiometer with a PCI backplate for speed
adjustment of the fan. Fan is attached by using clips made out of steel wire. Set of four such
clips is included so that one can attach two fans, one on the each side of the heatsink to get
maximum airflow through the fins.
Details

Base
Base of the unit is made out of copper. This way the heat from the CPU is collected more
efficiently and transferred to the heatpipes. There are total of four U-shaped heatpipes
attached to the base. This means that there are eight channels (pipes) transferring
the heat from the base of the heatsink towards the top.
