Zalman is primarily known for their kick ass CPU coolers. The CNPS9300 AT is no exception to this. With a unique patented `figure 8' heatpipe design this cooler uses the cooling of four heatpipes in only two. The CNPS affix to the model stands for Computer Noise Prevention System, which basically means this CPU cooler is perfect for quiet computers. This is the first Zalman CPU cooler that I have ever gotten a chance to look at and I am very impressed with the results of it. Read on further to see what I think about the CNPS9300 AT.

The Zalman CNSP9300 AT comes packed in a rather small package. The box is decorated with shades of blue and black squares of various sizes. The CPU cooler peeks through the plastic window on the front where we also find some of the awards that have been given to the CNSP9300 AT. The back of the box goes quickly over the support CPU's, the features, and some small images of the CPU cooler.

The cooler is tightly packaged in plastic is held together by the four plastic clips. Also inside of the box there is a bag with the User's Manual and all of the necessary hardware for installation.
