GlacialTech Igloo 5751 - a step towards compatibility

    Almost three years ago, GlacialTech released the Igloo 5750 processor cooler, which had support for all platforms that were relevant at that time. However, technological progress did not stand still, and during this very long time more than one family of new processors and platforms was born. And now, recently, GlacialTech introduced the Igloo 5751 cooler , which is essentially an updated version of the Igloo 5750 PWM. In addition to the previous ability to install Intel LGA 775 and AMD Socket 754/939/940, AM2, AM2, the GlacialTech Igloo 5751 received compatibility with Intel LGA 1156/1366 and AMD AM3. In this article, we will consider the question of how well this cooling system copes with modern systems.


    The GlacialTech Igloo 5751 CPU cooler comes in a cardboard box decorated in yellow-green tones. On the front side of the box is an image of the cooler and inscriptions informing a potential buyer about the name and multi-platform cooler. The top cover of the box lists the supported Intel LGA 775/1156/1366 and AMD AM2 / AM3 platforms for installation. Additionally reported compatibility with Intel Core i3 / i5 / i7 processors. A small additional bonus is the presence of the IceTherm II thermal grease syringe in the delivery set, as also indicated by one of the inscriptions.





    On the back of the box and its side walls, there is information about the technical characteristics of Igloo 5751, manufacturer’s contact numbers, website address, e-mail. This information is also available on the GlacialTech official website . Inside the box is divided into two sections. The first is the processor cooler itself. In the second section there are sets of fasteners, a syringe with thermal grease and a spatula for its application. All this is packed in a plastic bag, so as not to get lost during transportation.



    The overall dimensions of the Igloo 5751 cooler are 100 x 135 x 130 mm, with a mass of 550 grams. The radiator is based on four 6 mm heat pipes, on which 54 aluminum plates are strung. The plates are covered with a metal casing of golden color, on the sides of which the brand name of the manufacturer is applied.
    The manufacturer equipped the radiator with two fans of standard size 92 x 92 x 25 mm. The rotation speed of the upper fan blades is 1400 rpm. The lower fan is equipped with a rotation speed control system according to the PWM method (pulse width modulation), the rotation speed of the blades of which varies in the range of 800 (± 300) - 1800 (± 10%) rpm. According to the manufacturer, the top fan pumps up to 26.8 cubic feet of air per minute, while the noise level does not exceed 18 dB. The lower fan pumps up to 34.4 cubic feet of air per minute at a noise level of no higher than 26 dB. Nickel-plated copper base measures 33 x 33 mm and is equipped with an additional radiator. The ends of the heat pipes located at the base are laid in grooves and soldered. Traces of solder are clearly visible.



    But the quality of the processing of the base was somewhat surprising. Unlike the usual perfectly polished base of GlacialTech coolers, we see not only the absence of any kind of polishing, but also distinct traces of the cutter. Despite this, there are no complaints about the evenness of the surface of the base. The attached set of fasteners includes three fasteners equipped with plastic latches for installing the cooler on Intel LGA775, LGA 1156, LGA 1366 motherboards, respectively, fasteners for installing on the AMD AM2 / AM3 motherboards, four screws and a key. Separately, it is worth noting that now a syringe with thermal grease is included in the delivery package. Previously, thermal grease was originally applied to the base of the cooler.



    The fastenings for Intel motherboards indicate which platform they are designed for, so it is not possible to mix them up.
    The installation process does not cause much difficulty.
    We fasten the necessary fastenings to the base of the radiator. It looks like a heatsink with installed mounts for AMD and Intel LGA 1156. Then you just have to snap the plastic latches when installing on Intel boards, or using a special key or Phillips screwdriver and fasten the four screws to the standard backplate on the AMD boards, after removing the near-processor frame. Test configuration and testing methodology Processor - Intel Core i5 750 ES (2.67 GHz, Lynnfield, rev. B1)








    System board - Asus Maximus III Formula (Intel P55, Intel LGA 1156, BIOS 2001)
    RAM - Apacer, DDR3, 2 x 1024 MB, CL9-9-9-24, 1.5 V
    Video card - Asus GeForce 6600
    Power supply - Enermax EMG500AWT (Modu87 +, 500 W)
    Hard drive - WD3202ABYS RE3
    Cooling system - GlacialTech Igloo 5751. Testing was carried out in the operating system Windows Vista SP2.


    RealTemp 3.59.4 beta was used to monitor the temperature, Everest Ultimate Edition 5.50.2100 was used to monitor the fan speed, and Riva Tuner 2.24c was graphically displayed. The load was created using the graphical shell of the Linpack test - LinX 0.6.4 for 15 minutes using the entire free memory. The Intel Core i5 750 processor was overclocked to a frequency of 3600 MHz with a supply voltage of 1.325 V. The rotation speed of the lower fan blades was 1900 rpm. Testing was carried out on a horizontally located open bench. The temperature in the room at the time of testing was 22-23 degrees Celsius.

    Test results
    According to the test results, it is clear that the GlacialTech Igloo 5751 processor cooler is able to ensure the operation of modern processors in a fairly acceptable temperature mode, even in an overclocked state. The maximum temperature of the hottest core was 79 degrees Celsius. Of course, this cooler can in no way be attributed to the contender for the palm of leadership among air cooling systems. And the company GlacialTech itself is trying to produce cooling systems with good efficiency, low noise and at a very modest price. With a recommended cooler cost of $ 25-30 and compatibility with all modern platforms, I think Igloo 5751 will find its buyer.
