Cooler Zalman 7000A
At the end of March this year, we tested the cooler Zalman 7000Cu, the main purpose of which was a system for processors Intel. In addition, the kit was mounting the cooler for Athlon 64 processors, but AMD has pushed the release date of these processors in September. As a result, the cooler has been tested only on the CPU Pentium4.
It should be noted that the Zalman 7000Cu showed excellent results: a very efficient cooling with low noise. Moreover, at the minimum speed cooling fan can work virtually silent (according to the manufacturer – the noise level is 20dBa). But this cooler has been a serious disadvantage – complete mount for the absent processors SocketA.
Interestingly, among a large number of tested coolers platform SocketA no, that would be balanced by the cooling capacity and noise. All coolers are presented on the market have an obvious bias in either direction of maximum cooling or in the direction of the noise floor (at the expense of cooling, respectively). The most outstanding representatives of the first series were Thermaltake Volcano 7 + and Titan CU5TB, and of the quietest coolers can be noted a series of Zalman 30006000, Igloo Silent Breeze and the Titan TTC-D5TB (TC). Naturally the owners of the first to suffer from noise, but most were able to overclock the processor, and the owners of the second cooler – on the contrary .
There were craftsmen who crossed different types of coolers to give acceptable results, but once again – ready to tihimbesshumnym cooler fan and heatsink quality was not for sale.
Was really quiet Igloo Silent Breeze, but it was not suitable for overclocking than 2Ggerts with increasing voltage Vcore. The situation could fix the cooler CoolerMaster Aero7, to whom I personally had high hopes. However, at a maximum speed of its roar was unbearable, and at the minimum speed, the noise was minimal (but still felt), but suffered greatly the efficiency of cooling.
As a result, I have virtually buried the hope of finding the best air cooler for SocketA, but at this point, the Korean company Zalman coolers announced CNPS7000A. To the public were presented in two versions: with a full copper heatsink (-Cu), with a combined aluminum-copper radiator (-AlCu). In the end we managed to get both of the cooler.
We begin with the most expensive model – 7000A-Cu.
Inside the box we find the following:
Cooler Zalman 7000A-Cu
Fastening for Pentium4 motherboards
Fasteners for motherboards for the Athlon 64 (including the enforcement plate *)
* Fasteners for motherboards for Athlon XP (SocketA)
A tub of proprietary thermo paste
The device speed control – FanMate
* A label with the logo Zalman
A packet of silica gel (which would be in the temperature difference is not steamed wrap
* – Different from the complete cooler CNPS7000
We can say that all the changes were limited to the addition of a bag with fasteners for SocketA. Also in the bag with a mount for Socket754 added a metal frame to the back of the motherboard. Well, one more addition – a sticker with the logo Zalman )
It is worth noting that the design of the cooler CNPS7000A virtually no differences from its predecessor (CNPS7000).
The only difference is in the form of foundation:
As a result, we will not consider the installation of the cooler on a Socket 478 board, and immediately proceed to the installation SocketA. Mounting is very simple – two metal sites, which are installed on the motherboard with screws. To do this, are utilized four mounting holes on the sides of the CPU socket. Example:
On the reverse side of the card is as follows:
And what would the screws do not damage the surface of the motherboard they put on special washers, gaskets.
Almost immediately have the following thoughts:
Weight 7000A-Cu cooler is 773gr. Thats a lot, since according to the specifications of AMD weight of the cooler should not exceed 300 grams. It is clear that such a cooler is fastened at the teeth of the socket it would be wrong – so the mount through the mounting holes is the only sure way.
In my opinion, for mounting the cooler on SocketA would not prevent reinforcement plate on the back of the card. In this way, one would more evenly distribute the load on the cooler. Moreover, the package already includes a plate for the motherboard for Athlon 64 – it was possible to make a universal one.
And now the most important thing – almost all of motherboard manufacturers have sharply reduced the number of models with mounting holes. As a result, most motherboards SocketA Zalman7000A series coolers can not be simply put. Here are some examples: almost all motherboards Gigabyte, MSI and Elitegroup do not have these holes (I mean, of course, on the boards on modern chipsets). In addition, second-tier manufacturers also stopped making the mounting holes. For example, all the Soltek and Jetway, as well as many other card companies do not have any openings. And even one of the earlier revisions of Abit NF7 (-S) also produced without holes (but in revision 1.2 and 2.0 are back .
To its credit, marketing Zalman they did not hide the fact that many motherboards will be compatible with the new cooler. Instead, they held a series of compatibility tests, and put the results on display (though this list is inaccurate . In addition, the Zalman experts conducted a study of compatibility of the new cooler with various types of buildings. The fact that in some configurations (motherboard + casing) processor socket is located very close to the power supply. As a result, the cooler Zalman 7000A or will rest against a power supply, or it can even be installed.
And last – indicate serious difficulties when choosing a motherboard on which it was necessary to test these coolers. In addition to the presence of mounting holes, the board must provide the user with information about the actual core temperature. Almost immediately, I remembered the Epox 8K3A motherboard chipset KT333, but then changed his mind very much like to test on a modern motherboard chipset nForce II. And among these, only three display boards to py-kernel: a Asus A7N8X rev2.0, Gigabyte 7NNXP and Soltek 75FRN2-L. But the last two do not have mounting holes – remains board Asus.
That is, even at the initial review we can conclude that the scope of the cooler Zalman 7000A Socket462 platform will be very limited. However, this fact has little effect on the popularity of the product – the fact that this cooler can be installed on systems with processors Pentium4 and AMD Athlon 64 processors.
Continue the installation – after a metal platform mounted on the board, carefully put the cooler on the CPU and tighten the screws on the clip.
The cooler is fixed with two screws – and spinning them very carefully and evenly. The fact that an Athlon XP has an open core, and if the screws are not uniformly conclude, it may be skewed a radiator and as a consequence – cleavage core.
Another subtle point: in order to prevent bias on any processor heatsink SocketA has 4 rubber pads. So – Zalman 7000A heatsink is not on these pads completely. In fact – there is nothing wrong, except you can tear off the rubber gasket – and sticking them closer to the nucleus (though I did not do).
Thats it – installation is complete.
As for the cooler Zalman 7000A-AlCu, details of which we will consider it in the next roundup coolers SocketA. And now here are some photos:
The only thing worth mentioning – a model AlCu weighs much less: only 445 grams, which makes it possible to transfer the system unit to the cooler installed.
But for the pure copper model – carry the computer with the cooler is very undesirable. About this, even written in the user guide and on its website.
There is a separate line item allocated for that Zalman does not assume any liability for any injury: mechanical or related to overclocking (overclocking).
Naturally 7000A-AlCu cooler is cheaper than pure copper model. As a result, he will find a buyer.
Now the brief specifications cooler:
total surface area is 3170kv. see
The fan speed varies from 1350RPM to 2500RPM.
the noise level varies from 20dBa to 25dBa
To change the speed of the device is intended FanMate1, which is included.
