A Closer Look

The CNPS9500 LED looks almost identical to the CNPS9500 AT. The most obvious difference is the use of an LED fan. Like the CNPS9500 AT, there is a total of 90 fins connected to the heatpipes and they are quite thin, approximately 0.2 mm.

It still weighs the same as the CNPS9500 AT, which at 530 g is slightly more that what was specified as the maximum heatsink weight (450 g) for LGA775 and Socket 754/939/940 processors.

For those who had never seen CNPS9500 LED 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.

Unlike the CNPS9500 AT, the base of CNPS9500 LED has a mirror polish! Take a look at the picture below :

Not only was it nicely polished, the base is also very flat. In addition, this LED version of the CNPS9500 actually has a raised contact area on the base. The base of the AT version is completely flat.

The fan's rating is printed on the sticker located behind the fan. This is also where you can find the power connector for the fan.

Unlike the AT version which comes with a 4-pin connector, the CNPS9500 LED uses a 3-pin connector.

Motherboard compatibility-wise, the CNPS9500 LED stands out the most. It is compatible with many types of sockets and motherboards.

In addition, it's also quite impossible for the CNPS9500 LED to interfere with other components in your system. That is unless you are installing it in a low-profile system.
