Installation Tips

The cooler is fastened onto LGA775 the same way as Zalman 7700: you have to use a backplate on the reverse side and screw a clip to a frame. The installation onto Socket 478 also remained the same: there are two aluminum brackets that catch to the existing frame, and then the clip is fastened to these brackets with the two black screws shown above. The screws have hexagon-shaped heads that is why there is an L-shaped hex-nut wrench included with the package.

The remarkable changes have only been made to the way the cooler should be fastened onto K8 processors. Now this procedure has become much simpler. From now on you don’t have to take the mainboard out of the system case and remove the default retention frame. The clip can be fastened to this particular frame with the same screws that are used to fasten the frame to the backplate.

Some mainboards designed for AMD processors are equipped with a frame that is not screwed to the backplate, but is fastened to it with special plastic clips. In this case, you will need to remove the clip and use a block included with the cooler. This block is fastened with the screws at the bottom, and then the clip is screwed onto it.

The manufacturer recommends placing the Zalman CNPS9500 LED cooler in such a way that its fan is on the right-hand side and blew the warm air towards the case fans. It is very easy to do if you have an LGA775 processor: there are four fastening holes on the bracket, so you can turn the cooler in any direction. If the fastening holes are horizontal, the cooler will sit the right way on Socket 478 and K8 processors, as well. If the fastening holes are placed vertically, then you will have to move the clip in-between the heatpipes to fasten the cooler the right way.

Unfortunately, this was the only thing I couldn’t do. The clip is flat and is shaped unusually, so that you could allegedly insert it between the heatpipes sideways and then turn to the proper position. I could insert it between the heatpipes, but I failed to turn it the right way: the clip would catch to the heatpipes or to the bump in the middle of the top plate. Maybe I should have applied more effort, but it didn’t feel right keeping in mind the smart cooler construction and Zalman’s special attention to all smallest details.

By the way, I didn’t really understand why they included two clips, because they are of the same shape and size, except for the fact that one is slightly longer than the other and has a few additional holes. According to Zalman, the longer clip (L-type) is needed for socket 939 mounting. But we are going to double-check that.
