Zalman CNPS11X Extreme CPU Cooler Review

The Zalman CNPS11X Extreme CPU Cooler




Out of the clamshell you can see that the black framed fan with seven opaque blades is already screwed onto the front. The wiring is taped to the frame and you can see it terminates with a 4-pin connector for PWM functionality.




From here you can see how the fins are angled from wide in the front to narrow in the back as they almost touch. You can also see that not only is there a black plastic cap over the fins; there is a similar one under them as well.




Two things I wanted to show off with this are the center support made of aluminum that the top and bottom caps screw into and it supports the back of the fins for spacing. I also wanted you to see how the bends are made in each of the five plated heat pipes to make the transition from the base to the fins.




Go ahead and blow this image up and give it your own fin count. I could be wrong, as one count was at 83, but two resulted in 82 fins, so that is what I am sticking to.




The plastic cap on the cooler functions for a couple of purposes; one it makes for a much cleaner top to look at, and the other is it made a place to add this large "X" with CNPS11X in chrome over it.




When I was going to take a shot of the base and mounting hardware, I noticed that you can now see a layer of plastic under the fan. This will add a bit of spacing, but I think the fan is screwed into a frame rather than the fins of the cooler at this point.




Two things I really like to see in the base of this cooler. In the 10X coolers there were only Phillip's heads on the mounting screws, and I stripped mine. I love that the groove is cut for a flat head driver. Oh, yeah, and this finely polished black nickel coated, copper base plate!




I was right, after pulling the fan screws, a screw in the cap and a pair on this face plate I was able to remove the fan and the top cove and expose this inner frame. The heat pipes are very tall and now I really appreciate that cap!




I just thought this was a cool angle to look into the cooler from. I noticed at this time that the bottom cap also has the "X" logo, even though you will never see it. Running from the bottom to the top in the back is the thick black, extruded aluminum spacer to make the cooler a more solid unit when bolted down tightly.




Since I had the fan removed, I figured I might as well get a shot from the inside and let you get a look at the specifications and part number on the sticker.
