Test new coolers GlacialTech 7300 for Socket 939

Test new coolers GlacialTech 7300 for Socket 939

Do not stand still progress – the new processors come out, there are new coolers. The processors are getting hotter, coolers are getting bigger. Even cooler, and strives to overcome the weight of the pound abroad. Often, pound abroad of copper and heat pipes. The idea of ??water cooling, which is firmly in the air a couple of years ago, have not entered the stage of mass distribution, and no wonder – the organization of such a system requires a set of functional units: a cooler, hoses, radiator, pump, fluid reservoir. And all this together takes a lot of space, rarely compact place these components within the enclosure, and those of the cooling system that fits inside is usually not high performance, but surely stand a high price, like any CBO. In other words, it was not possible to make a compact, cheap and efficient NWO, and this idea has remained the lot of adventurers and enthusiasts. But more and more processors are heated … In the course went to the copper heat sinks and heat pipes are set, but the price of such products has risen to the level of 40-50 dollars, but it is not enough.

Not so long ago, we had to test the new coolers GlacialTech Igloo 5071 companies, it is interesting that the coolers do not contain a single gram of copper and no heat pipe were able to show very good results, and even managed to secure a considerable overclocking! That is, not everything is solved and the copper heat pipes. It may be a form of thought and a good heatsink fan can still cope with the new processor? GlacialTech has not proved many times that “Yes, they can”. In addition, the aluminum cooler is not only lightweight, but also low cost, and this is probably the decisive factor.

The present review is devoted to the new line of coolers GlacialTech Igloo 7300 under the title. These coolers are designed for AMD processors with the jack socket 754 and socket 939 and belong to a class of inexpensive cooling devices – the value of all models in the area of ??10-14 U.S. dollars. The radiator has a whole new line of a single form for all models and is made entirely of aluminum.

The characteristics of all coolers are presented in the table, which is shown in the box:

As you can see, Igloo 7300 promise to deal with virtually all modern processors, but the most powerful models such as the AMD Athlon 64 FX-57 and older models of dual-core processors AMD. Claim is not weak for a simple aluminum products. As always, within the same line, the company GlacialTech coolers differ only used by fans, who have the same size and shape, but different speed.

Model “Light” has a very slow and quiet fan – his speed is around 1900 r / min., And the noise level is almost beyond the limit of audibility – a total of 21 dB inside the case it will be completely silent.

The second model is the base, and is simply called Igloo 7300, the rate of the fan is located in the vicinity of 2400 r / min., And published by the noise has become distinctly hear – his level is 27 dB.

Overclocking designed a special version of the Igloo 7300 Pro, it is equipped with the most productive fan speed which is about 3000 r / min. with the noise level about 35 dB. For a 90 mm fan speed is always connected with high noise, so that, gentlemen, overclockers will have to pay for the megahertz decibels.

The latest model of Igloo 7300 series has the suffix “TC”, which stands for “Thermal Control”. Fan of this model has a built in temperature sensor and is capable of adjusting the rotational speed from 1500 to 3000 rev / min. The fan speed varies depending on the temperature sensor.

Igloo 7300 coolers come in a small colorful packaging, on the walls showing in detail the characteristics of all models, as well as with the visual images describes a method of installation.

Excerpted from the cooler box attracts attention with unusual rounded shapes, but in general, its structure can not be called particularly original.

Massive aluminum radiator has a base figure, designed probably more evenly distribute the heat between the ribs. The ribs also have different heights and are made wedge-shaped. This design provides less resistance to air for cooling a large area.

As you can see, nothing particularly unusual at first glance, not, as we recall, GlacialTech cooler features is thought to the smallest details of the shape radiator, through which high efficiency is achieved by using inexpensive material – aluminum.

Igloo 7300 much larger than the standard boxed cooler AMD, and the corresponding fan is used.

All this coupled with the special shape of the radiator promises, the assurances of GlacialTech, to ensure reliable cooling of almost any modern processor, AMD.

At the base of Igloo 7300 caused an even layer already known to us highly efficient thermal compound, which proved to be excellent in the Igloo 5071 coolers review. From dust and finger caused by thermal interface is protected by a plastic cap.

Freed from the base of the thermal compound is not impressive quality of processing – the traces of sanding is absolutely clearly visible, but to touch base quite smooth and not like sandpaper and close.

Of course, neither of which reflected a screw can be no question, but the rating of “4″ the quality of treatment it is drawn. In addition, a great brand GlacialTech thermal interface is easy to cope with the irregularities of the ground.

Igloo 7300 coolers mount so elementary that it and especially do not need to describe. The cooler is fastened to the frame of the standard on the motherboard with a tight guard, which clings to the teeth of the six standard frame around the CPU socket.

A simple turn of a lever, and the cooler is firmly pressed against the processor. Removing the cooler as easy as installing it, but heres the second time in the thermal interface may no longer be enough.

Used the fan is quite common, but has a wide blade impeller with an aggressive slope.

Produced, as before, by Everflow, hes done with the use of ball bearings, ensuring long life fan. All four models are identical to the cooler in the form of a fan, is allocated only a model with the suffix “TC”. As mentioned earlier, a fan of this model has an automatic speed control, depending on the temperature sensor built into the fan. Thats how it looks:

This little green thermal diode and threw 5 grams of the total weight of the cooler. But since he has no contact with the radiator, fan speeds do not depend on the CPU temperature on the temperature of air supplied to the fan blades. Well, if this air will be supplied from outside the body through a duct casing made in compliance CAG? Then the temperature of the air blowing sensor, will be the same, and automatic control will not work. But the buildings with ductwork on the side comes more and more. The idea of ??a variable speed, of course, is good, but its implementation is, frankly, ineffective. This thermal diode will work properly only in a sealed enclosure with no duct, and no additional fans. But even in this case will have a high inertia, as radiator can heat up very quickly, and increase the fan speed only when the temperature rises in the general case.

Still, the automatic speed control for the Igloo 7300 would be very out of place. The fact that the noise level of 92 mm fan since 2000 rev / min. becomes clearly visible. Feel comfortable only when the Igloo 7300 Light, Igloo 7300 noise, a fan speed 2400 r / min., Begins to have a little bit annoying, especially the ears, sophisticated silence. But the model Igloo 7300 Pro and howling at all, so that scores all the other fans of 35 dB – you are not a joke.

Although an acceptable level of noise – also a relative concept, though, to compare with. For a man accustomed to the roaring monsters of the past, the noise from the 7300 Pro does not seem high, but for humans, pampered quiet cooling systems it is still high. This question is more personal. 35 dB – this is not the highest noise level for the cooling system is 45 dB or more. But comfort can be called the noise level of 20-25 dB, so the group gets a quiet cooler Model Igloo 7300 Light and Igloo 7300 is partially TC. But again, this opinion of the author, a comfortable sound level for each there own.


AMD processors with the transition to 0.09-nm process technology have become noticeably less warm and cool because they made it much easier. One need only look at the box cooler AMD, which is designed to cool the entire family of AMD Athlon 64 processors.

Its design is so simple and unpretentious, that this in itself suggests that even the simplest cooler is able to cool even the most powerful processor AMD. While older models of dual-core Athlon 64 X2 processors have already used the new box cooler, which is used in the design of heat pipes.

The list of processors that can cool the Igloo 7300 is very broad, and bring it again would be too cumbersome, you can read it on the specification at the outset. Summarizing it can simply say that all of Igloo 7300 will cope with any processor Sempron and Athlon 64 processors, even ektrimalnye Athlon 64 FX-51 and FX-53 it on the shoulder. Dual-core processors are supported up to Athlon 64 X2 4200 +. And all of these processors can be cooled aluminum cooler with no frills? Is this true? Lets check.

To test series Igloo 7300 coolers have compiled the following stand:

Used by the body has a very powerful ventilation system – in case there are five additional 80 mm fan. But to get closer to the actual conditions of all the fans were powered by the voltage is not 12, and +5 V, and the rate of rotation was 1000 rev / min.

Power Supply FSP FS400-60PN has a large 120mm fan with variable speed, but in the process of testing the temperature is almost not changed and therefore the fan speed has been consistently low.

To simulate a more powerful video cards, which differ in significant heat release, Galaxy GeForce 6600GE been overclocked to 600/1290 MHz.

Testing occurred in the three most relevant modes of operation:

Mode of rest. In this mode, the system does not perform any demanding task. Normal office work, browsing pictures, music and other things. The resulting temperature was shot after 20 minutes of work with texts and tables.

Game mode. This is the second most common problem on your computer. Game is loaded to the maximum all the components of the system, because the overall heat computer at this moment reaches a maximum Svoge. The temperature in this mode, the shot after half an hour running game test suite 3DMark 2003.

The maximum load. This mode is more testing “strength” for cooling the CPU. Performed this test program, the infamous S & M version 1.7.2. The essence of this test is simple – the processor performs a kind of simple calculation with floating point (FPU) for half an hour. Moreover, this calculation is organized so that the processor uses all its resources without a trace, and the load it is not weakened, and for a split second. This mode provides maximum heat output of the processor on which it is capable of. Because you can with great confidence pains to say that if the cooler to cope with the processor in this mode, the problems with its cooling it in the future he will not arise. Still, you can add that to squeeze out as much heat from the processor can not be any real desktop application.

AMD Athlon 64 3000 + (s939) is the first step in a series of processors s939 AMD Athlon 64, but we have them, of course, does not confine. In order to show how to cope with the Igloo 7300 “big brothers” our processor was overclocked to 1800 MHz to 2700 MHz, the voltage at the same time had to raise from 1.4 V to 1.55 V. Note that the frequency of the processor at the same time greatly exceeds a threshold of 2.4 GHz, which established the company Glacial Tech for its new line of coolers, but its even more interesting – well see how much they are suitable for overclocking.

Thus, the results to you:

Well, well! All three coolers have shown better performance compared with the boxed cooler AMD, but this mode is apparently “childish” for all the studied devices – the temperature never rose to 50 degrees, and the model 7300 and Igloo 7300 Pro show and did nearly the same performance. They clearly need a more powerful processor.


And here, 50 degrees, and more. Using a more powerful processor immediately became clearly visible difference between the models 7300 and Igloo 7300 Pro, but the AMD boxed cooler is not able to cope with the testing until the end – at the maximum load the computer hangs after a few seconds.

In fairness, I note that for the standard AMD cooler is not used by its native interface, and better quality Fanner-420, but even this did not save him. In testing the same model is not involved Igloo 7300 TC, this is due to the fact that at maximum load speed of its fan speed is compared with the model Igloo 7300 Pro, and at the minimum speed it runs like a model Igloo 7300 Light, because there is no sense cluttering schedules the same results. In addition, even with slow fans, the case ThermalTake Xaser II provides excellent ventilation, and air temperature inside remains almost unchanged, and in such a situation, adjustment mechanism Igloo 7300 TC will be completely ineffective.

All models of the new line from Glacial Tech coolers have been successfully tested in standard mode and overclocking mode. Only Igloo 7300 Light for acceleration to get very close to the line of instability of the processor, but there is also ambiguous – in the mode game temperature is not reached and 50 degrees, and applications, such as “hot” as S & M does not, because we can say, Igloo 7300 Light all coped well with overclocking.

Coolers examined, tested passed. Its time to put the assessment:


High performance

Low cost

Ease of construction

Easy to install


High noise the older models

Not the most effective mechanism to adjust the speed model Igloo 7300 TC

As you can see a lot of pros, and they are all significant. Disadvantages also exist, chief among them – the noise. The second minus the somewhat controversial. As mentioned above, the automatic fan speed control will work, but with good ventilation case c, or, even more so, ductwork, automatic regulation of traffic on this principle is totally useless.

The other model series Igloo 7300 proved to be quite well and are not weak claim to a place in the body. The main claim – a good performance with very low market value.

Aluminum is in no hurry to take the position!
