Product Description

Amazon.com Product Description

Zalman's CNPS7700-Cu cooler for Intel/AMD Motherboards and CPUs offers a large, high-efficiency fan and pure-copper base material to ensure excellent heat dissipation. It also works with a range of prominent CPUs and motherboards, including Intel Pentium 4 (Socket 775), Intel Pentium 4 (Socket 478), and AMD64 (Socket 754/939/940). When it's set to silent mode, the cooler generates no noise or vibrations.

The large, 120 mm fan inside the cooler's FHS maximizes cooling performance by providing sufficient airflow over a large area, cooling not only the CPU, but the VGA card, Northbridge, FET, and RAM--even at slow rotation speeds. The supplied adjustable fan speed controller (Fan Mate 2) lets you control fan noise as well as performance.

The maximum weight for a cooler (fan) is specified as 450g (.99 pounds) for Intel Socket 775/478 and AMD Socket 754/939/940. Special care should be taken when moving a computer equipped with a cooler that exceeds the relevant weight limit (the CNPS7700 weighs 918g). Zalman Tech is not responsible for any damage that occurs when moving a computer.

What's in the Box
Fan, heat sink assembly, 4 grips (2 each for S-type and L-type), 4 bolts, thermal grease, fan speed controller (Fan Mate 2), double-sided tape (for installing Fan Mate 2), cable for Fan Mate 2, a user's manual (in English and Korean), 1 clip support for Socket 775, 1 backplate for Socket 775, 4 clip-support fixing bolts, 2 clip supports for Socket 478, 2 nipples, 1 backplate for AMD64, and 1 set of washers.

Note: No motherboard components with a height greater than 39mm (1.53-inch), as well as the PSU, disk drives, VGA card, and RAM should be present within a 68mm (2.68 inch) radius from the center of the CPU.

5.0 out of 5 stars Replace your generic heatsink with the big Zalman heatsink fan silent cooler combo, April 25, 2006

By

This review is from: Zalman CNPS7700-CU 120mm 2 Ball Cooling Fan (Personal Computers)

This is very big. It will be like a big wheel that will take up about a quarter of the size of your motherboard (mobo) with your central processing unit (cpu; processor) at its centre. It looks small in the picture but the unit is 136mm in diameter (5.35") and probably the biggest component in your computer next to the mobo and power supply unit (psu). To top it off it requires a full dismantling of the system to install because of a back support plate that goes onto the rear of the mobo. The fan inside the spreading metal heatsink is 120mm fan that can run at around 2000 RPM max creating 32 dB but there is a controller with the unit, called a Fan Mate 2, that allows you to control the speed of the fan and so decrease the noise. Apart from its enormous size the unit weighs in at a whopping 2.7 lbs which is 0.7 lbs heavier than the Zalman USA CNPS7000B-AlCu CPU Fan. So maybe you might want to check out the other model instead unless you are really interested in overclocking cooling, but still this product is not really designed for overclocking so the risk is your own. Given that the cooler is so big they have gone to great lengths to create a very harsh to install support frame that will test a novice who may want to consider getting a professional to install it unless you are happy taking out your mobo. You should also double check that this Zalman heatsink supports your mobo as they have dropped support for certain types of mobos. So check before you buy. Installing the actual heatsink is not such a big deal as the parts are very well designed but it does require that you have front and back access to your mobo. You may also find this to be a bit of a squeeze with your PSU unit so again maybe doing some measurements before you buy is a good idea. I found zero clearance between my PSU and the cooler. It literally just breezed against it. The unit is a silent solution not an overclocking solution even though it can be used with overclocking. For those looking to create a cooler, less noisy computer, the Zalman will replace that noisy generic heatsink with a silent one. Your system will also be a little cooler, but not a whole pile, and in some cases there will be no discernable drop in temperature. It is the quietest air-based CPU cooler on the market. That is what is was designed for and that is exactly what it does. If you can't sleep because your computer sounds loud then this will probably help you get some extra forty winks. You may have to disable the generic case fan to hear the silence and of course hard drive activity will play a part in noise, but as for getting rid of a major noise culprit - the generic heatsink, this Zalman is the best around. Just get it, install it, or find someone who can. It is worth it.

5.0 out of 5 stars This thing is big!, February 8, 2005

This review is from: Zalman CNPS7700-CU 120mm 2 Ball Cooling Fan (Personal Computers)

This was my first CPU heat sink/fan purchase and I have been very pleased! I've been interested in overclocking my P4 2.8GHz processor for quite a while now and my research uncovered this product. The pictures don't do it justice....it is really, really large!

It weighs just over 2 lbs. and has a radius and height of nearly 7 cm, but it's one of the coolest looking units out there, especially the all copper version.

Installation only took about an hour, including removing the old heat sink, cleaning the old thermal paste off of the processor, installing this one, and mounting the fan-speed controller. I have a socket 478 mother board, so the whole process was very easy since you can work with the existing mounting brackets. The only tricky part was getting the screws into the mounting brackets but I don't mind challenges. Also, make sure you pick up some Arctic Silver 5 thermal grease as this is some of the best stuff out there.

What most impressed me was the immediate performance increase and reduction of sound. My stock Intel cooler was very loud, but even amidst all my case fans, I could tell it was quieter. Before, my processor temperatures were about 29-30 *C in idle and 45-50 *C under full load. Now it idles at 25-27 *C and doesn't even break 40 *C at full load. I was very impressed by the nearly 10 *C drop under full load! I hear that Arctic Silver 5 runs more efficiently with 1-2 weeks of "break-in" time, so it may even improve still.

Overall, it looks great, runs quiet, performs well, and installs easily. I would highly recommend this unit to all potential overclockers.

5.0 out of 5 stars Zalman quiets the leaf blower on the Dell 8400, October 26, 2005

This review is from: Zalman CNPS7700-CU 120mm 2 Ball Cooling Fan (Personal Computers)

My sons computer was so loud that we referred to it as the leaf blower. We assumed that his fan had gone bad (bearing) but found on line that an extremely loud fan was a feature of his Dell dimension 8400. We also found a web site from someone in England that had replaced his Dell cooling tower with the Zalman and had fabulous results. He detailed how to modify the brackets and we had to buy a power cable converter.
The results have been astrounding. The Zalman keeps the CPU so cool that the stock Delta fan never goes above its lowest speed and therefore is very quiet. And the Zalman makes almost no noise.
We are quite happy with the result.
