Zalman CNPS2X CPU Cooler
The CNPS2X has either 99 or 100 copper fins (I counted three times and got different results on each) surrounding the 11 blades of the 80mm fan with the responsibility of cooling these fins. The cooler is a bit fragile and the fins will bend easy as seen around the edge in this image.
From the side of the cooler, you can see that each fin has a spacing tab to try to make the fins stay as symmetrical and perpendicular to each other as possible. Even with just the slightest handling, you can see that some of those are out of alignment already though.
I removed the fan from the cooler to get a better look at what is going on with this cooler. Flipping the fan over, I found there is a model sticker here showing the ZE8010ASM naming. This also signifies that this fan is 80mm in diameter and stands only 10mm from the sticker to the front of the fan hub.
You will see the holes in the base soon enough, but that is where these angled tabs clip into the bottom of the CNPS2X. This is handy to allow for this to be removable as it should make cleaning it much easier. The only bad thing is you need the cooler off the board to remove the fan.
With the fan out of the way, you can see that the inside edges of the fins all start to radiate from on top of the puck in the center, and are soldered into place. The square holes on the wither side of the number 2 are where the fan clips in, and it is very snug once snapped in place.
Once the cooler is flipped over is when you will notice the mounting system holes and the S-pipe. The S-pipe runs through the center of the base, and to add strength and better thermal transfer the fins are soldered to it. As for the four threaded holes around the base, those are for the hardware to mount to.
Moving in much closer, I did find gaps on either side of the S-pipe as it splits the copper plated aluminum base. The surface is flat across in both directions, but is left in the rough milled state. It is also stated that this pipe section should always be parallel with the ground when installed for best results.
