A Closer Look

The CNPS9500 looks pretty much like two sets of CNPS7700 fins mounted vertically, with three heatpipes connecting the fins to the base. In contrast, the CNPS7700 fins are directly connected to the base.

There is a total of 90 fins connected to the heatpipes and they are quite thin, approximately 0.2 mm. But thanks to its copper construction, the total weight of the CNPS9500 AT is 530g. That is actually slightly more that the maximum cooler weight specified for the LGA775 socket.

For those who had never seen CNPS9500 AT closely before, you will probably think that it has 6 heatpipes. In fact, it only has 3 heatpipes.You will see what we mean when you take a look at the pictures below.

Basically, the heatpipes start and end in the heatsink base. Starting from the base, the heatpipes go upwards and twist like the figure 8, and end on the opposite side of the base.

Unfortunately, the CNPS9500's base does not have mirror polish. The slight machine marks are clearly visible. However, the base is flat, which is actually more important than the mirror polish.

The 4-pin fan connector is located at the back of CNPS9500. The extra pin allows you to control the fan speed via a fan controller, if you have one.
