It would seem that in the construction of air cooling system with heat pipes to date have all been invented and tested. Previously we tested countless tower coolers, the design of which can already be called a classic, tested the effectiveness of cooling systems which use only one tube of large diameter, experienced performance spherical radiator on the tubes, and even a couple of "missiles" heat pipes failed to start (though still only in the waste basket). Simply put, what did not was because "of tube" cooling systems in various price categories in our laboratories for all this time.

Meanwhile, cooling systems manufacturers, despite temporarily suspend the growth of heat dissipation of modern processors are not going to rest on our laurels and continue to develop and launch production in its new coolers. However, there are thus known brands differently. For example, all of the Zalman known, releasing a new model CNPS8700 LED , positioning it primarily as a cooling system for a compact and low-profile enclosure system blocks. In addition, according to the manufacturer's press release, it is stored in the new cooler cooling efficiency (including blowout okolosoketnogo space), and also low noise.

Another company - Thermaltake - do not beg the question to reduce the size of its new items, cooler Thermaltake the V1 , and launched into the creation of the cooling system for the overclocker-aesthetes receiving from the appearance of the cooler is not less satisfaction than the overclocking results achieved by means of it. I think you will allow me to lower the assessment of the aesthetic component trends in today's article, the benefit to do this to each of you, even on the following images will not be any difficulty. But from the point of view of overclocker and it needs no Zalman CNPS8700 LED, nor ignore the Thermaltake V1 we could not, so now present you their detailed review and testing.

1. Zalman CNPS8700 LED: compactness and efficiency

New from the South Korean company Zalman comes in the familiar packaging of the manufacturer. The outer shell is a cardboard box with cut-outs on the front and back sides:

A complete list of specifications, a list of supported processors and platforms, key features of the cooler, and much more can be learned from studying the case. Inside is a plastic corset, securely locking the cooler and stacked on top of the supplied accessories, among which the following components are included:

  • plastic frame mounting the cooler on the LGA 775;
  • backplate for the motherboard with LGA 775;
  • universal mounting clip with removable tip;
  • Zalman sticker with the logo;
  • fan speed control FAN MATE 2 and cable thereto;
  • double sided tape to set the FAN MATE 2;
  • four screws for attaching the frame to the LGA 775;
  • thermopaste Zalman CSL850 (zinc oxide, 1.2 W / m * K);
  • instructions for installing the cooler

When you first look at the Zalman CNPS8700 LED understand that its structure resembles the structure of the good old Zalman CNPS7000 and 7700, in the time-proven as the unprecedented performance of the cooling system. Pialoobraznuyu radiator shape more confused with something quite difficult:

However, it's worth looking at the radiator side or from below, once it becomes clear that we face a very different cooler than copper "ingot" weighing almost a kilogram.

Skeleton structure of the cooler are two copper heat pipes with a diameter of 6 mm. They come out of a copper base, closed top aluminum plate, and they strung a large number of copper ribs have a thickness of only 0.2 mm:

Both tubes are held in two tiers, distributing heat flow uniformly over the entire area of ​​ribs and closed at the bottom. By modern standards, the cooler can be attributed to a low profile, because its height is only 67 mm and weighs less than 475 grams. On each edge has stamped the name of the manufacturer.

To provide structural rigidity contact points between the heat pipes are soldered:

Soldered themselves at the bottom of the tube:

If you remove the fan and mounting plate, it is possible to detect that the soldering between the tubes is not entirely uniform, somewhere it is visually seen more and somewhere less:

However, all this nitpicking, because the most important places to contact the tubes this "bowls" and the copper base have been well soldered to each other, not only the joints of pipes.

The aluminum plate is screwed to the base and covering the tube, performs a support function to the clip attachment and is not in contact with the tubes:

To her the two aluminum legs mounted fan impeller:

In Zalman CNPS8700 LED mounted fan size 110 x 25 mm, i.e. a conventional impeller of 120 mm fan. Fan Marking - ZF1125BTH, and it is based on two ball bearings. The rotation speed is regulated within the kit variator FAN MATE 2 in the range from 1150 to 2350 rev / min. When connecting the fan directly to the motherboard (without FAN MATE 2) rotation rate is increased to 2550 rev / min at the maximum noise level of 35.5 dB.

The evenness of the base and the quality of its perfect polish:

A relatively long time I have not seen such a high-quality surface of the base. Bravo Zalman!

Now about compatibility and installation. Zalman CNPS8700 LED can be installed on all modern platforms. Motherboard with Socket 478 and, moreover, Socket A (462), according to the Zalman, to date does not include, so installing a new cooler for them is not provided. Mount the cooler on the motherboard with sockets Socket 754/939/940 and Socket AM2 made clamping clip with removable tip that is included with the cooler supply that needs to catch the teeth of a standard plastic frame. Motherboard in this case not be removed from the system case, which is not the platform for Intel processors with LGA 775 socket.

However, for the Zalman CPU coolers, installation principle, in which you first need to screw down through the board plastic frame, already familiar to our regular readers, and should not cause a sharp negative:

Especially because the frame is attached to the backplate, prevents bending of the board and increasing the clamping force to the base of the cooler the CPU heat spreader:

Note that the installation of such form elements backplate on the back side of motherboard do not create any interference (tested on motherboards ASUS P5B Deluxe, P5K Deluxe and P5N32-E SLI).

Well, then we insert all the same clip and the engagement between the pipes for her privornutuyu plastic frame.

As you can see, the cooler is compact and lower "skirt" does not go beyond the boundaries of the plastic frame. For potential buyers, concerned about the possibility of pre-installation of the cooler on its board, the Zalman gives dimensions for each platform on a single scheme:

According to this scheme, a radius of 61.5 mm from the center of the processor elements should not be above 39 mm.

Inside of a chassis Zalman CNPS8700 LED is as follows:

Against the background of tower cooler Zalman CNPS8700 LED downright kid. At night, the cooler fan will delight lovers of modding a soft blue light.

The recommended price of new items is stated at the level of US $ 40-50.

2. Thermaltake V1 (CL-P0401): stylish cooler for enthusiasts

Next novelty released by Thermaltake under the slogan "A stylish cooler for enthusiasts" (though, for what it is enthusiastic, it is not specified). The box is large, but the cooler, as well as with the Zalman, used in about increasingly the open to a potential buyer, and see there is something:

The box is also full of comprehensive information, but inside it is a plastic shell molded in the form of a sealed cooler and tape the perimeter:

So that nothing will fall out, and, most likely, will not break at the time of, for example, forwarding. At the bottom of the package is a small cardboard box with accessories supplied:

It is composed of two brackets for LGA 775 and screws to them, clip for Socket 754/939/940 / AM2, instructions for installing the cooler and a bag of thermal paste.

Look at the Thermaltake V1:

That's really really very original. Nothing of the sort among the cooling systems we are used to for sure have not seen.

cooler radiator consists of two fan-shaped parts (hence, apparently, and went cooler name V1), each of which is suspended on a pair of copper heat pipes with a diameter of 6 mm:

That is, the heat pipes in the cooler design has four, not two, like Zalman CNPS8700 LED. The total number of edges is equal to 102 (2 x 51), and their thickness is 0.2 mm. The ribs are in contact with the tubes by means of hot melt adhesive instead of soldering, as it might be ideal. As a result, some of the ribs can be a little push on the tubes, but by themselves they do not dangle freely.

Between such a kind of radiator halves mounted impeller 120 mm fan whose diameter is 110 mm:

The air flow from the fan cools immediately both halves of the radiator, one - stream for intake, and the second - at the blow-out. On both sides to preserve rigidity radiator coupled pair of plates that are put on the ends of the heat pipes.

fan impeller is fixed on a metal rack, but only in one position:

That is, to turn the fan on the air flow direction in the opposite direction is impossible, although it is difficult to suggest who may be required. I should add here that the fan with the TT-1225A labeling (Everflow) is equipped with three LEDs of blue light.

Attached to the fan speed controller, configured in the form of a small "process":

Wire short and speed adjusted very uncomfortable inside the system case. Nevertheless, thanks to the speed control, fan speed can be varied in the range from 1300 to 2000 rev / min at the maximum air flow in 86.5 CFM and a noise level of 16 to 24 dBA (traditionally undervalued for Thermaltake).

Photo cooler below:

Tube at the base as well as at the Zalman CNPS8700 LED neatly soldered:

And the plate that serves as the basis for fixing the fan and cooler mounting plates, is very similar to the judges from Zalman and also not in contact with the tubes:

Exemplary mirror polishing the base at Thermaltake V1 not, however, its processing quality is very high:

Flatness base verified fingerprint thermopaste on glass, also does not cause any complaints.

Installation of the cooler on the elementary platform supports. In the flatbed processor K8 Thermaltake V1 presser fastened clip, which is inserted between the tubes, and then engages the teeth of the plastic frame. Ability correct orientation within the computer chassis in this case is limited to two positions and the arrangement of the plastic frame on the motherboard.

In the case of a platform for LGA 775 to the base of the cooler is necessary to screw the attachment with plastic latches, nails:

Well, then evenly diagonally dent these same latches in the motherboard holes. the pressing force in this case is sufficient to provide efficient heat transfer. The cooler does not rotate on the heat spreader. You can be directed to any of the four possible directions in the LGA 775 Thermaltake V1. As has become clear from the described installation procedure to remove the motherboard from the system case will not have to in any of the cases.

Mounted on the motherboard Thermaltake V1 is compact and can hardly create any interference elements okolosoketnogo space:

And here is how it looks from Thermaltake novelty inside the system case:

Note that two photo cooler installed in different ways: in the first case, the heat pipes are oriented parallel to the rear wall of a system unit housing, a second perpendicular or simply in a horizontal plane. the manufacturer is not indicated in the installation instructions, specifically in what position it is necessary to install the cooler. In principle, the heat pipe orientation in space does not matter, so from Thermaltake engineers did not dwell on this. As it turned out, correctly, that did not, as in the tests, no differences in the temperature regime at two ways of cooler orientation was identified.

Thermaltake V1 recommended price is stated to be 40 ~ $ 50 and comparable thereof from Zalman CNPS8700 LED.

The next step we have with you the technical characteristics of the coolers.
