Zalman CNPS-7700-CU


The Zalman CNPS-7700CU CPU cooler is a huge but silent cooler. From the picture it is hard to tell but it is massive. It is 136mm in diameter. That is about 5.35 inches. It is made up of a large number of copper plates in a flower formation with a 120mm silent low rpm fan in the middle. Because of its sheer size and amount copper that makes up this heatsink it weighs in at about 918 grams. This is way over the maximum weight stated for Intel retention sockets which could cause some issues. With the fan at full speed which is 2000rpm in generates about 32 dbA which is quite loud. That is why Zalman includes the fanmate 2 fan controller. With the fan controller its range of speed is 800-1800rpm. At its lowest setting what Zalman says is true, it is silent. I put my ear right next to it and I can’t hear any noise coming from it at all.

closer look

As this version is 918 grams it is super heavy and you should be super careful when moving your case if you have it. also it is kind of expensive at around $50 at Newegg. There is also a aluminum-copper version that is only 600grams and costs a lot less. Also this CPU cooler has a nice finish on the base, this is normal with Zalman brand coolers.

It comes with all the brackets to mount it on socket 775, 1155, 1156 and AMD 754, 939, and 940. The brackets securely hold it to the motherboard so the extra weight doesn’t damage anything. Even though it weighs so much I’ve never had a problem with it bending the motherboard or anything.


Although this heatsink was huge it still was relatively easy to install. Even someone who hasn’t installed an aftermarket heatsink before could manage it. I didn’t run into a single problem when I was installing it on a Intel socket 775 based motherboard.

first you just put the bracket on the motherboard which consists of a bottom plate and a top plate with screws holding it together.

Then you simply put the thermal paste on the CPU, and then you put the CPU cooler on the CPU and fasten the screws to the bracket and your done. Then to use the fanmate 2 controller you plug one end into the motherboard and one end into the fan you want to control. then you use the velcro to put the controller on the side or top of your case. The only problem with this CPU cooler is the fact that it might not fit on your motherboard or in your case.


I ran into a little problem with this testing part. I will try to fix it as soon as possible. This is the only motherboard I have that will fit this CPU cooler. It has a Pentium 4 560 which core-temp will not support so currently I can’t find a way to measure the temperatures. If anybody has a solution for this problem please leave a comment to give advice on how to get around this problem.
