From the top you can see the fan that uses a 4-pin PWM connection to the motherboard. Notice how the fan is a little larger than the heatsink, this will provide extra cooling to the surrounding motherboard components like the power VRM circuits.
On the side we see the two heatpipes that aid in moving heat from the bottom of the heatsink to the upper fin area closer to the fan. You can also see the length of the cable which is long enough to reach the top half of the motherboard.
Here we have a better look at the fin area. You can see how ThermoLab cut the fins so they produce less noise.
The fan is connected with the wire hanger method, something that has been gaining popularity over the last couple of years.
From the factory, the heatsink comes with pre-installed heatsink paste pre-applied. We also get a good look at the mounting system. When installing the heatsink you will need to remove your Intel Socket 775 motherboard, place the cooler on the processor and run the supplied screws to the heatsink through the holes. The brackets on the heatsink flex allowing the correct amount of pressure to be applied to the processor.
The CPU to heatsink contact surface is shiny, but not perfectly flat. As you can see in the image there are a few machine marks on the surface.
