Packaging and Parts

The packaging for the Zalman CNPS9900 LED is actually quite attractive. Zalman has standardized their marketing strategy for quite a while now, and the graphical elements on the front panel fall right in line with their marketing plan.

The back panel has a basic list of features and a better window to see the back of the heatsink itself. I also prefer to have large windows to see what the heatsink actually looks like as opposed to having a bunch of verbiage that I can get from their website.

This heatsink is packaged in a plastic shell that has been molded to fit the CNPS9900 LED perfectly. It has four buttons that need to be unsnapped to remove the heatsink from its packaging.

Zalman includes all the retention clips and brackets to mount the CNPS9900 LED to all Intel Socket 1366/775 and all AMD Socket AM2+/AM2/754/939/940 CPUs.

They also included a user manual, thermal compound, screws, retention clips, and a case badge.
