Comparison of expensive coolers for socket SocketA. Q3 `2003

Comparison of expensive coolers for socket SocketA. Q3 `2003


Most recently, we have tested several cheap coolers for powerful processors (Barton 2000Mhz). In the review focused on the ability of the cooler to cool the processor at stock speeds. And in todays tests will involve more expensive coolers, which take into account when developing possible overclocking the CPU (this CoolerMaster Aero7 and Thermaltake Volcano 11). In addition, we test the coolers that are designed for maximum quiet operation (Zalman 6000Cu and Igloo SilentBreeze).

But before you begin testing, I would like to respond to a couple of typical questions that have arisen among readers of the previous review:

1) Why skimp on the cooler if you bought an expensive processor.

If for some systems are absolutely no plans to overclock, as well as an upgrade in the next year or two, then this system is quite enough of the cheapest cooler that can cool the processor adequately. In addition, AMD processors are rapidly becoming cheaper, so the recent high-end processor will soon become available to the public.

2) Why has not got to test one or another cooler (most frequently mentioned coolers Igloo :) .

Frankly, the division into deshevyedorogie coolers rather conditional: the fact that for some expensive models begin with the price 300 rubles, and for someone with 500 rubles. Of course this varies with a set of coolers. And that would somehow link the results of both tests, we included the results of the cooler Titan TTC-CU5TB, which showed the best performance among the cheapest (in my opinion) cooler.

I note that this review is one of the last platform comparisons coolers SocketA. The fact is the Athlon XP has come to its logical conclusion – was released last (probably) XP3200 + processor on the Barton core with FSB 200 (400DDR) Mhz. I managed to get to test a processor, and its maximum acceleration voltage was increased to 2450Mgerts. This means that the clock speeds of processors made by 0.13tehprotsessu reached their technological limit. And the only thing left in stock at AMD, a maximum of one issue – two processor models with a frequency not exceeding 2.3Ggerts. The probability of this is small enough – after 2 months in a broad sell go Athlon 64, and manufacturers of cooling devices have focused on this sector of the market (a typical example – Zalman 7000Cu).

The description of each cooler, Ill pay attention to the ease of mounting. Also, do not forget about such factors as the reliability of fastening the radiator size, material used, appearance, processing quality, etc. Most of these factors is also quite subjective (especially the look :) , so Ill try to give plenty of illustrations.

Cooler Master Aero7

The appearance of the cooler is very unusual – it is standard on the radiator is a massive plastic construction with a turbine.

Actually the turbine and is a distinctive feature of the cooler Cooler Master Aero7.

Its use allows you to completely remove the so-called “dead zone”, ie area in which air movement is minimal. Almost all the traditional coolers with fans, in varying degrees, suffer from this drawback. Some manufacturers even try to fight this phenomenon (for example – Cooler Igloo 2320 (Pro)), but only Cooler Master has turned completely eliminate the “dead zone”.

What would this statement was significant, I conducted the following experiment: set the radiator fan Aero7 normal 70mm fan (taken from the Igloo 2500 Pro).

After that, a hybrid of several hours spent in a fairly dusty environment. And then I took off the fan and the layer of dust has determined the direction of air flow.

As clearly seen in the photo, in the central area of ??the radiator fins do not have a layer of dust, in contrast to the outer regions. This means that the center of the movement of air is almost 0, which naturally degrades performance.

Now look carefully at the turbine:

range of speeds from 1900RPM to 4500RPM, and the air flow depending on the speed of rotation is 10.9 – 26.9CFM.

Dimensions = 70h70h70mm turbines. As a result, the cooler becomes quite high and in some case may not fit (in those with the power supply is located above the CPU socket).

The speed of rotation of the turbine is installed by the user. For this purpose, is a control unit (variable resistance) with a metal handle. Something like this we have repeatedly encountered (particularly in the cooler Zalman and Thermaltake), but the engineers at Cooler Master brought the convenience of controlling up to perfection. First, the metal handle (also a plus – a cheap plastic part would spoil the appearance) is quite large, resulting in turn it is a pleasure. Second, the speed control unit is inserted into the depths of the body (like Zalman Fanmate), and can be installed either on the rear panel (instead of an expansion card), or 3 “chamber. For this are two plugs:

Specifically, we note that the 3 cap is made of aluminum, resulting in the owners of this noble kurpusov (among computer enthusiasts :) metal will not spoil the look of the front panel.

To power the cooler is a regular molex connector, in addition there is a separate wire that can connect to the motherboard and thus determine the speed of the turbine.

The radiator is made entirely of copper and the base of the heatsink is polished well enough (about 7 out of 10 points). It is also interesting to note that all the edges have a small

bend for greater efficiency.

Finally a few words on mounting – the cooler is quite heavy (over 600g), so it is not surprising that the clip has caught on all three of the tooth socket (each side). And the fastening clip is perfectly balanced by the rigidity and elasticity. As a result, installation and removal of the cooler is very easy. Significant role in this play is very long and wide palm fingers – but it can bring a cooler Aero7 owners a lot of trouble.

First, on some motherboards, this plate can prevent the installation of memory modules:

The boards with different arrangement of the socket, there may be other problems. For example on the board Epox 8RDA3 + socket is located very close to the edge, resulting in a plate rests on the power supply (for the case Inwin). But if you take the body a little higher, then the problem disappears.

Now about the noise level. So absolutely silent cooler Aero7 can not be named: even at the lowest speed of rotation of the turbine – with short-term (15-20s) off you can hear the noise change. Then – at higher speed, the noise increases quite considerably, and is already at around 3500 RPM the noise starts to put pressure on the head. And the maximum speed of the cooler noise heard throughout the apartment :)
