Coolers Igloo 5070, 5070 Light, 5070 PWM and 5050
Glacialtech has presented a new line of coolers - Igloo 5070 and 5050 which is aimed at Intel LGA775 processors.
Like most coolers made by this company, the Igloo 5070 series offer one type of radiator and a number of fans with various specifications.
In particular, the generic model offers a 90 mm fan of rotational speed 2800RPM, noise level 32dBa and generates 46.50CFM air flow. The Light model is aimed at those who want quietness, and thus the fan runs at the reduced speed - 2400RPM. The air flow generated amounts to 39.80 CFM, with the noise level not exceeding 28 dBA. On the contrary, Igloo 5070 PWM is positioned as a solution for computer enthusiasts. That is why the fan runs at speeds within 800RPM to 3800RPM, which allows generating air flow within 13.30 CFM to 63.10 CFM. Therefore, the noise level varies within 18.0 dBa to 40.0 dBa. Note that the latter cooler does not offer a speed regulator. But, unlike the models 5070 and 5070 Light, it is equipped with a 4-pin power connector. This allows adjusting the rotational speed with the motherboard's features.
The cooler's package is quite commonplace - a white cardboard box. Inside, apart from the cooler, we found an enforcement plate on the board's reverse side.
Note that this plate is fully made of metal, and to prevent the contacts from closing it is separated from the board with a rubberized washer with a gluing substrate. The glue is so sticky that after the laborious removal of the plate residues of the washer are still there on the motherboard.
On the whole, the procedure of cooler installation is easy enough and is much easier than installation of a boxed cooler. First of all, the enforcement plate has to be glued, then there goes the cooler and then tighten the screws uniformly.
Despite the ease of installation, you have to mess around with the cooler for quite a long time. Besides, there are certain issues of compatibility to some motherboard models. In particular, many Asus motherboards (e.g., a test specimen of P5AD2-E Premium) offer a system for cooling the power supply module - Stack Cool. Its component part is an aluminum plate on the reverse side of the board:
As a result, the fastening screws of the Igloo cooler partially don't reach the enforcement plate, so the cooler is not firmly pressed to the processor.
The radiator of Igloo 5070 series offers quite an intricate shaped base as well as great number of fins of various height.
On the aluminum radiator, there are is a fan attached with wired spring-loaded clips and two screws. As regards the cooler base, it is also made of aluminum. A layer of thermal interface is pre-applied to it, which is protected with a plastic lid.
Note that each cooler of 5070 series weighs 551 g. Coolers 5070 and 5070 Light are aimed at installation on Pentium4 processors of clock speeds not exceeding 3.4GHz and maximum heat emission level no more than 84W. The more powerful cooler 5070 PWM is therefore aimed at more powerful processors of clock speeds up to 3.8 GHz and heat emission up to 115W. These requirements are given without any "margin of safety", so should be strictly followed.
As regards the Igloo 5050 cooler, it is a boxed cooler, by and large.
The shape of the radiator is coincident with that for Intel coolers.
The differences are about the shape and characteristics of the fan. On the 5050 model, there is a 90 mm fan of rotational speed 2800RPM, generated air flow 46.50CFM, and the noise level = 32.0 dBA.
The base of the cooler offers the same layer of thermo interface (again, it is protected with a plastic lid). The procedure of installation and removal of the cooler matches that for a boxed cooler.
It should be noted that the Igloo 5050 series includes two more models: 5050 Light and 5050 PWM. Although we haven't received them for tests, let's bring in the specifications of the fans. On the Light model, there is a cooler of 2400 RPM rotational speed, generated air flow 39.80 CFM, and noise level 28.0 dBA. The specifications of the fan of 5050 PWM cooler are as follows: 800RPM - 3800RPM, 13.30CFM - 63.10CFM, and 18.0dBA - 40.0dBA. That is, if you have some spare time, you could remove the fans from coolers of 5070 series and test the coolers 5050 Light and 5050 PWM series at home by simply changing the fans. As you may have guessed, the design of the radiators of series 5050 is the same.
The pros and cons of all the coolers of Igloo 5070 and 5050 series are almost matching, so we have summarized them all into a table:
Pros:
- Low noise level of models 5070, 5070 Light, and 5050
- Relatively small weight
- Middling cooling efficiency
Cons:
- Some inconvenience of installation
- Incompatibility to Asus motherboards and the Stack Cool system
- The gluing layer is too sticky on the enforcement plate
