Installing the CNPS7000-Cu is fairly easy. You can check out the installation process here The first step is to put a nice thin layer of thermal paste onto your CPU. Once you’ve got that on, you slide the two retailing rails into the Pentium 4 retention bracket. When you’ve got the rails in, you simply screw the heat sink to the rails and hook it to the Fan mate. Then attach the Fan mate to the CPU fan header on your motherboard. Once you’ve got it all setup, just put the motherboard back in your case and re-connect everything. Installation takes about 20-45 minutes, depending on how careful you are putting things together. You do want to be careful screwing the heat sink to the rails. One turn too many and you may end up with a cracked motherboard or CPU. The other thing you have to be careful with is that you don’t bend the fins of the heat sink as you’re installing it.

I ran two tests on the cooler. The first was a semi-real life test of booting the system up. Letting the temperature stabilize and then playing 30 minutes of Battlefield 1942. The second test was to boot the system up. Let the temperature stabilize and then run the SiSoft burn-in tool 10 times in a row and taking the highest number reported from the log. One note, these tests were run on an Abit BH7 motherboard, which tends to report temperatures on the high side so your mileage may vary.

As you can see, the Zalman CNPS7000 is cooler than the stock HSF in both normal and silent mode in both tests by a few degrees. The cooler is an improvement over the stock cooler but is a few degrees cooler worth the risk with the heavier heat sink and the cost? I’m not necessarily sure it is. I’m not a hardcore LAN gamer but I do move my PC around quite a bit and I was kind of nervous moving the system with the cooler in it.

If you don’t move your system much and don’t mind spending the extra money, the Zalman is a solid product. However, if you move your system around a lot, then you may want to consider another HSF (Zalman does make a similar product that’s mostly aluminum). At around $40, it’s also a little on the higher end price wise.

The CNPS7000-Cu is a very attractive unit but its significant weight and cost are cause for consideration.
