Updated line of coolers GlacialTech

Visiting our editorial staff is the first cooler from the company GlacialTech and hopefully not the last. GlacialTech Igloo 5761 positioned as a mid-range solution for cooling processors, without a significant overpayment for the brand. Meet GlacialTech Igloo 5761 himself.

The Igloo 5761 is an updated model of the highly acclaimed Igloo 5760. The new cooler has a different fan with 4-Pin control, a slightly different mount, and a lower cost.

Packaging and equipment

The hero of our review is packed in a blue box. On the front of the package there is a window through which you can see the fan and part of the radiator of the cooling system. GlacialTech Igloo 5761 is a multi-platform cooler and is installed on LGA 775/1155/1156 sockets from Intel and FM1/FM2/AM2/AM2+/AM3/AM3+ from AMD.

The maximum allowable thermal package of the hottest Intel processor should not exceed 105W, and the processor from AMD 140W.

A diagram of the cooler in two projections is shown on one of the side parts of the package. Dimensions GlacialTech Igloo 5761 are 90 x 96 x 128 millimeters in height, width and length, respectively.

The cooler is packaged quite simply, the cooling system is in one compartment, a set of fasteners and documentation in another. GlacialTech Igloo 5761 is delivered already assembled, that is, the fan is already mounted on the radiator.

The delivery set is quite modest. User manual and mounts for Intel and AMD. There is thermal paste, but it does not come in a separate bag or in a syringe, but is already applied to the sole of the cooling system radiator.

Design features

GlacialTech Igloo 5761 is built on the principle of top design. The heat sink and main heatsink combine three 6mm heatpipes. The heat pipes themselves are nickel-plated. From above, the radiator closes the cooler with a size of 92 x 92 x 25 mm, which blows not only the radiator of the cooling system itself, but also the near-socket space. The weight of the cooler is 350 grams.

On the outer aluminum plate of the radiator of the cooling system is the name of the company and the model of the cooler.

The base of the cooler, covered with thermal paste of an unknown company, is protected by a plastic cover.

The thermal paste applied to the base of the cooler is a rather thick substance, which also has small pellets.

There were no traces of soldering heat pipes to the base of the cooler. It can be assumed that the heat pipes are clamped in the grooves of the heat sink by pressing the base of the cooler.

The technology of direct contact of heat pipes with the processor cover has its pros and cons. In the opinion of our editors, this method is more suitable when using this cooler on AMD processors, with their large heat-distributing cover area.

Cooling fan model JT9225M12S003A produced by the same company GlacialTech. A seven-bladed turntable with yellow blades has an operating voltage of 12V and a current of 0.28A. Thanks to PWM control, the fan speed can vary from 800 to 2300 rpm. The maximum airflow is 43CFM and the noise level is 30dBA.

Installation

The cooler is installed in the same way as the one we recently reviewed in our editorial board. The fastening we need is placed using four screws.

Thanks to the yellow color of the blades GlacialTech Igloo 5761 looks at motherboard unusual, standing out with bright colors.

Installation random access memory cooler won't hurt. In terms of dimensions, the GlacialTech Igloo 5761 is so compact that it is only slightly larger than a boxed cooler.

GlacialTech Igloo 5761 has been tested on a medium static user configuration. The Intel Core i3-2120 processor used is a fairly popular model among most users on this moment. This will allow many readers to compare the test results with the results of the cooling systems they have on hand, as well as evaluate the difference in cooling efficiency.

For 100% CPU load, our editors use the Prime95 program. To monitor the temperature, the RealTemp program is used, and to monitor the cooler speed - speedfan program. In comparative testing, in addition to the participant in today's review, cooling systems, and GlacialTech Igloo S26 took part. The room temperature during testing was 25°C.

Evaluating the results of the GlacialTech Igloo 5761, we can say that it is behind the other test participants, outperforming only its fellow GlacialTech Igloo S26. And if the significant difference in results between Igloo 5761 and Deepcool Gammaxx S40 can still be attributed to a higher technical equipment and more high price the latter, then the noticeable loss of Igloo 5761 to the Thermalright True Spirit 90 cooler is no longer possible to close one's eyes. Moreover, the Igloo 5761 cooler refused to run at 1000 rpm, minimum values which started from ~ 1200 rpm.

Conclusion

Passing the tests GlacialTech Igloo 5761 left mixed impressions. On the one hand, this is a fairly inexpensive cooler costing about 700-750 rubles, from which you should not expect impressive cooling results. On the other hand, a noticeable loss to the Thermalright True Spirit 90 cooler, which is an equal competitor in terms of cost, does not give full confidence to recommend GlacialTech Igloo 5761 as the optimal purchase of a cooling system up to 750 rubles. Pluses:

simple and convenient fastening;
PWM adjustment;
multiplatform.

Minuses:

complete thermal paste of dubious quality;
non-competitive cost of the cooler relative to more efficient models of competitors.

Weighing all the pros and cons, as well as general impressions after testing the device, our editors award the cooler GlacialTech Igloo 5761 fair reward i2HARD- silver.

Despite the fact that the Taiwanese company GlacialTech (www.glacialtech.com) is quite young (founded in 2001), its products are well known both on the Russian and international markets. GlacialTech coolers are renowned for their high quality, efficiency, reliability and value for money. The last circumstance played an important role in the fact that GlacialTech coolers gained wide popularity among PC builders. Actually, according to some estimates, in the OEM segment, GlacialTech coolers occupy about 30-40% Russian market. In the retail segment (in the segment of boxed coolers), the share of GlacialTech is not so large. However, the company does not target its products to the end-user market. That is why in the line of its coolers you will not find "fancy" expensive models with copper radiators, heat pipes and 120mm fans, which are positioned for extreme overclocking. Although boxed coolers are also present in the product range of this company. There is even one model focused on gaming PCs, but this is more of an exception than the rule. Still, the company's main products are low-cost OEM coolers.
In this article, we will review three new models of GlacialTech coolers: Igloo 5063 Silent (E), Igloo 5058 and Igloo 5073 Silent. The first two models are OEM coolers aimed at PC builders, while the Igloo 5073 Silent cooler comes in a retail box.

GlacialTech Igloo 5063 Silent (E)

Igloo 5063 Silent (E) cooler is designed for Intel processors with LGA775 socket. This cooler is aimed at system integrators involved in serial assembly of PCs and is positioned as an effective replacement for the standard boxed cooler.

As follows from the technical documentation, this cooler is designed to cool processors with a TDP of less than 95 watts.

The Igloo 5063 Silent (E) cooler has a three-pin connector and supports the technology of changing the fan speed by changing the supply voltage. The cooler is equipped with a classic clip-on mounting system to the motherboard, which facilitates the process of its installation and dismantling. It is a classic round radiator made of aluminum plates, on top of which an 80-mm seven-blade fan is mounted with four screws. The overall dimensions of the cooler are 89x89x67 mm. Device weight - 341 g.

As follows from the specifications, the maximum fan speed is 2000 (±10%) rpm, while the fan at maximum speed creates an airflow of 26 (±10%) CFM. The declared noise level is 20 dBA.

GlacialTech Igloo 5058

The Igloo 5058 cooler is also designed for Intel LGA775 processors and is also aimed at system integrators involved in serial PC assembly.

As follows from the technical documentation, this cooler can be used in conjunction with Intel processors with a heat dissipation of less than 95 watts.

The Igloo 5058 cooler is equipped with a clip system for fastening to the motherboard, and its design exactly repeats the Igloo 5063 Silent (E) model. The difference is only in the height of the radiator. So, if in the Igloo 5063 Silent (E) model the radiator height is 35 mm, then in the Igloo 5063 Silent (E) model it is 25 mm. At the same time, the dimensions of the cooler are 89x89x55 mm, and the weight is 263 g.

The Igloo 5058 cooler also uses an 80mm seven-blade fan with a three-pin connector, which is attached to the heatsink with four screws. However, the declared characteristics of this fan are somewhat different from those of the Igloo 5063 Silent (E) model. Thus, the maximum rotation speed is 3200 (±10%) rpm, and the fan generated at top speed rotational airflow - 44.1 (±10%) CFM. It remains to add that the declared noise level is 32 dBA.

GlacialTech Igloo 5073 Silent

Like the two previous models, the Igloo 5073 Silent cooler is designed for Intel processors with an LGA775 socket. However, unlike the two previous models, Igloo 5073 Silent is already a boxed version of the cooler. This model available with two types of fastening: classic clip-on system and bolt-on fastening system. In the latter case, a mounting bracket is supplied with the cooler, installed on the back of the motherboard, to which bolts are screwed. In general, it should be noted that the system of fastening the cooler with bolts is usually used in expensive and bulky models. In addition, it has a number of obvious disadvantages. For example, it is impossible to install a cooler if the motherboard is already installed in the PC case, but replacing the cooler requires a complete dismantling of the computer.

As follows from the technical documentation, the Igloo 5073 Silent cooler is guaranteed to dissipate up to 95 W of thermal power, and, accordingly, it can be used in conjunction with Intel processors Intel series Core 2 Duo, Intel Core 2 Quad, Intel Pentium Dual-Core, Intel Celeron D, and legacy Intel Pentium 4 processors with TDP less than 95W.

The Igloo 5073 Silent cooler is an aluminum radiator with vertically arranged fins. A 92 mm fan with a three-pin connector is mounted on top of the radiator with four screws, which supports rotation speed control by changing the supply voltage. The assembled cooler measures 92x92x78mm and weighs 410g.

As follows from the specifications, the maximum fan speed is 1700 (±10%) rpm, while at maximum speed the fan creates an airflow of 32.5 (±10%) CFM.

Note that the fan is based on a 1B1S ball bearing, and the declared noise level generated by the cooler is 20 dBA.

Test Methodology

Any cooler must ultimately meet two main criteria. Firstly, it must cope with the cooling of the processor at any load, and secondly, it must be quiet. If the cooler meets these two criteria, then it does not matter at all what its rotation speed is, what air flow it creates, etc. Therefore, when testing coolers, we focused on measuring two characteristics - cooling efficiency and the level of generated noise.

As you know, there are two main ways to control the speed of the cooler. The first is to dynamically change the supply voltage on the cooler. That is, as the processor temperature rises, the cooler supply voltage also increases, and, consequently, the fan speed increases. The voltage range is usually between 6 and 12 V, however, for some motherboards, the lower voltage limit may be less than or greater than 6 V.

Coolers that support dynamic voltage change technology are equipped with three-pin connectors: two pins are used to supply voltage, and the third is used to transmit a tachometer signal, which allows the controller on the motherboard to determine the current fan speed. The principle of operation of the tachometer is quite simple. For each rotation of the fan impeller, two rectangular voltage pulses are generated. Knowing the pulse repetition rate (tachometer signal), you can calculate the fan speed (Rotation Per Minute, RPM). So, the frequency of the tachometer, expressed in hertz, is related to the fan speed by the formula: RPM (rpm) = f(Hz) 60/2.

The second way to control the fan speed is to use pulse-width modulation (Pulse Wide Modulation, PWM). A special PWM controller on the motherboard generates a sequence rectangular pulses supplied to the fan controller. These pulses are used as control signals for a kind of electronic key, which periodically connects and disconnects the fan from a supply voltage of 12 V. The frequency of the control PWM pulses remains unchanged, only their duty cycle changes, defined as the ratio of the time at which the PWM signal is at high voltage, to the duration of the entire pulse.

The typical PWM pulse repetition rate is 23 kHz, the typical amplitude is 4.5 V, and the duty cycle varies from 30 to 100%, however, the lower duty cycle limit, amplitude and frequency depend on the specific PWM controller and may be slightly different.

All coolers that support PWM technology have a four-pin power connector and, at the same time, they necessarily support the technology of dynamic change in supply voltage.

Measuring the dependence of the cooler rotation speed on the supply voltage

Since the fans of all tested coolers had a three-pin connector, that is, they supported the technology for controlling the rotation speed by changing the supply voltage, we measured the dependence of the fan rotation speed on the supply voltage.

To measure the dependence of the cooler rotation speed on the supply voltage, a special stand was used, including a BORDO 211A digital oscilloscope, a digital voltmeter and a reobas, which allows you to smoothly change the supply voltage on the fan in the range from 5 to 12 V.

The fan was powered by a reobas, the supply voltage was controlled using a digital voltmeter, and the fan speed was determined from the tachometer signal, which was controlled using a BORDO 211A oscilloscope.

Measuring the noise level generated by the cooler

To measure the noise level generated by the cooler, we used a stand consisting of a power supply with passive system cooling, reobass and a Center 322 sound level meter, which was located vertically above the cooler at a height of 15 cm.

The noise level was measured with the fan supply voltage in the range from 5 to 12 V in 1 V steps.

Note that the noise level was measured using a non-standard method, so the figures we obtained cannot be compared with the noise level values indicated in technical specifications, however, it can be used to compare fans in terms of noise level.

Determining the Cooling Efficiency of a Cooler

Speaking about measuring the cooling efficiency of a cooler, let's first define what is meant by cooling efficiency. As we have already noted, each cooler must eventually cope with the cooling of the processor under any load. That is, the cooler must create such conditions for heat dissipation so that even with 100% processor load for a long time, the processor temperature does not exceed the critical value at which thermal protection is triggered. It is clear that the greater the difference between the critical temperature of the processor and its current temperature at 100% load, the more efficient cooling the cooler provides. Therefore, under the cooling efficiency, we mean the difference between the critical temperature of the processor and its current temperature (hereinafter Tj) at 100% load.

Note that in order to control the temperature modern processors Each processor core has a dedicated Digital Temperature Sensor (DTS). This sensor controls exactly the difference between the current temperature of the processor and its critical temperature, that is, it controls the value of Tj. As soon as this difference becomes equal to zero, the thermal protection of the processor is activated. In principle, knowing the critical temperature of the processor and the value of Tj, it is very easy to determine the real value of the current temperature of the processor. But the problem is that for different processor models, the value of the critical temperature is known only approximately. Moreover, the critical temperature value may differ even for two different instances of the same processor model. That is why it is more correct to track not the current value of the processor temperature, which can only be determined approximately, but the difference between the current and critical temperatures.

Of the utilities that are able to determine the value of Tj, Real Temp and Core Temp applications can be noted.

To test the cooling efficiency of the coolers, we used a quad-core Intel Core 2 Extreme QX9650 processor with a clock speed of 3.0 GHz. This processor has a TDP of 130W and is one of the hottest ones right now. Of course, the fact that the TDP of the processor is 130 W does not mean that this is its real heat dissipation. Recall that the heat dissipation of the processor and its TDP are not the same thing. The TDP of the processor only indicates how much thermal power the cooler must dissipate in order to ensure that the processor does not reach a critical temperature during operation.

It is clear that if during testing it turns out that the cooler is capable of cooling the Intel Core 2 Extreme QX9650 processor, then with the cooling of any dual-core processor of the Intel Core 2 Duo family with a TDP of 65 W, as well as with cooling of the quad-core processors of the Intel Core 2 Quad family with a TDP of 95 W he will be able to cope even more so.

When measuring the cooling efficiency, the cooler was connected not to the connector on the motherboard, but to the reobas, which made it possible to set the supply voltage in the range from 5 to 12 V and thereby change the fan speed. To determine the cooling efficiency, the processor was loaded at 100% using special utility our own development for 10 minutes - this was quite enough to establish thermal equilibrium and stabilize the processor temperature. For each value of the supply voltage in the range from 5 to 12 V, the value of Tj was determined with a step of 1 V using the Core Temp 0.99.4 utility. Thus, a graph of the dependence of Tj on the supply voltage was built at 100% processor load. From the graph, you can evaluate how efficiently the cooler cools the processor. The higher the Tj value at each voltage value, the more efficient cooling the cooler provides under these conditions. If, for example, at the maximum fan speed (supply voltage 12 V) the value of Tj is more than 30 °C, then this means that the cooler is effectively coping with processor cooling and there is a temperature potential for overclocking the processor. In addition, by determining from the graph at what voltage the value of Tj will be 5-6 °C, we can estimate at what minimum fan speed the cooler will provide sufficient cooling for the processor at 100% load.

Test results

The test results for GlacialTech coolers are shown in fig. 1-3.

As can be seen from fig. 1, the maximum rotation speed of the Igloo 5063 Silent (E) and Igloo 5058 coolers correspond to the declared one. But the maximum speed of the Igloo 5073 Silent cooler turned out to be even slightly higher than the declared one: instead of 1700 RPM, the real maximum speed for this cooler is 2010 RPM. In general, the speed characteristics of the Igloo 5063 Silent (E) and Igloo 5073 Silent coolers are practically the same.

If we take the change in fan speed as a change in the fan speed when the supply voltage changes from 6 to 12 V, then for the Igloo 5063 Silent (E) cooler the fan speed change range will be from 790 to 2000 RPM, for the Igloo 5073 Silent cooler - from 840 up to 2010 RPM, and for the Igloo 5058 cooler - from 1470 to 3200 RPM.

Despite the fact that the Igloo 5058 cooler is the fastest, it is somewhat inferior to the Igloo 5063 Silent (E) cooler in terms of cooling efficiency, but at the same time it outperforms the Igloo 5073 Silent cooler. Thus, at the maximum fan speed (voltage 12 V) and 100% processor load, the Tj value for the Igloo 5073 Silent cooler was 44 °С, for the Igloo 5058 cooler - 38 °С, and for the Igloo 5063 Silent (E) cooler - 33 °C. It should also be noted that all three coolers are very efficient and successfully cope with the cooling of the Intel Core 2 Extreme QX9650 processor in any mode of its operation. Moreover, even at a supply voltage of 6 V, that is, when the cooler rotation speed is minimal, all three coolers are able to provide cooling for the Intel Core 2 Extreme QX9650 processor in its maximum load mode. Thus, for the Igloo 5058 and Igloo 5073 Silent coolers, the Tj value under these conditions is approximately 25°C, and for the Igloo 5063 Silent (E) cooler, it is 12°C. Thus, we can state that these coolers provide efficient cooling of any processors even at the minimum fan speed. Moreover, the Igloo 5058 and Igloo 5073 Silent coolers have a large margin of cooling efficiency and can be recommended for overclocking processors.

As for the level of noise generated by coolers, the situation here is as follows. Our sound level meter has a lower sensitivity limit of 30 dBA. This level of noise is perceived by the human ear as complete silence. That is, if during the measurements it turned out that the noise level created by the fan is 30 dBA, then this means that it is simply impossible to hear it even with the help of a sensitive device.

The quietest of the three coolers was the Igloo 5063 Silent (E). Our sound level meter was able to fix the noise it creates only at a supply voltage of 12 V, that is, at the maximum fan speed. With a lower supply voltage, it was simply impossible to hear this cooler.

The Igloo 5073 Silent cooler becomes inaudible at 7V, and at 12V it generates a noise level of 35dBA, which is very good result. Thus, the Igloo 5073 Silent cooler can also be positioned as very quiet.

The Igloo 5058 cooler can be heard even at 6 V (32 dBA of noise), and at maximum fan speed, the noise level rises to 41 dBA, which is quite noticeable.

Summing up the test results of three models of GlacialTech coolers, we can draw the following conclusions. Igloo 5063 Silent (E) can be positioned as an efficient and very quiet cooler that can provide cooling for any processor in its normal mode. This cooler can be recommended for use in home multimedia centers and home PCs. Igloo 5073 Silent can be positioned as a highly efficient and very quiet cooler that can provide cooling for any processor. Moreover, it can be used even for overclocking the processor, that is, in the mode when the heat dissipation of the processor exceeds the nominal nominal value. Such a cooler can be recommended for use both in home multimedia centers and home PCs, as well as in high-performance gaming PCs. The Igloo 5058 can simply be positioned as a highly efficient cooler - it does not belong to the low-noise category.

Members summary testing. The hero of today's review is in the back in the center.

The cooler we are considering GlacialTech Igloo 5750 PWM is part of the GlacialTech Igloo 5750 cooler line, which also has a Silent variant. These two coolers (PWM and Silent) differ from each other only in the fan speed - both coolers have two 92mm fans, only the Silent fans rotate at a constant speed (1400 rpm), while the PWM has a fan speed fans variable (from 800 to 2500 rpm). In other respects, these coolers do not differ from each other in any way.
