Review cooler CoolerMaster Jet4
The company produces CoolerMaster cooler for two categories of users.
First – this is normal users who require replacement of “boxed” cooler.
I do not remember that we have tested these coolers, and in any event of interest to them – is low.
The second direction – it is cooler for overclockers, as well as owners of the fastest
processors. Competition in this market sector is very strong, and most manufacturers
use a variety of techniques to improve performance (performance
noise reduction, etc.). But there is another direction that is actively developing “kulerostroenie”: a better appearance. In fact, all companies are making additional changes that emphasize the exclusivity of high-end cooler. As examples patterned grilles, fans, lighting, or gold plating the radiator.
And now the company CoolerMaster took a big step in this direction has been born
The main idea is clear immediately after the first glance: the designers
CoolerMaster cooler is constructed like a jet engine. Just say – no practical value of this construction is not. It is intended solely for the aesthetic satisfaction .
Under the appearance of a jet engine turbine hides, which sucks the air from one side, and sends it to a copper heat sink. That is the principle of operation is identical to Jet4 cooler that was used in Aero7.
The most important advantage over conventional turbine fan is the lack of
“Dead zone”, ie area in which air movement is minimal. And in a review Aero7 we found that the assurances of the effectiveness of the turbine CoolerMaster untrue.
Yes, and the cooler itself is a lot like Aero7. In particular, it has a similar control
speed, the handle of which can be located in the 3 “inch body compartment, so
and on the rear panel. In both cases use special plugs that are included.
By the way a complete set list:

Now consider the most important specifications cooler.
Firstly it is designed exclusively for the platform Socket478 (Celeron, Pentium4) and incompatible
with AMD-systems. In a sense, this drawback, because more and more
manufacturers move to produce a universal mounting design coolers
which allows the use of the past for any platform (a typical example -
Gigabyte 3D Cooler).
The next parameter – the weight of the cooler: approximately equal to 700 g. This is more than the stipulated
specifications of Intel, but do not worry: the plastic frame of the CPU socket is easily
withstand pound load (confirmed by tests coolers Zalman 7000Cu (773gr)
and Zalman 6500B-CU (898gr)).
Also worth noting is that the height of the cooler than 160mm (16cm), which may hinder
(Or make it impossible) the installation in the hull, with a vertical supply.
Go back to the look. What would be better to convey the impression of a cooler I will
photos from all sides.
Front view. A distinctive feature – the beacon, as a real aircraft.
Probably made in order to avoid any clashes in the wilds of the system unit .
Side view. The unique style of cooler emphasizes special logo “Jet” (the way it is
Rear View. To enhance the resemblance to the jet engine, the rear of the turbine is made
in the form of the nozzle. In addition, it is highlighted in red, which gives the impression of “jet exhaust”
Now a few words about the noise level. As expected from the jet engine,
at maximum speed, the turbine noise greatly. By reducing the speed
Noise is reduced to a minimum, but not completely disappear. However, this problem most
Coolers: even if the speed controller, the range of variation does not allow
achieve truly silent operation.
Its time to bring the official specifications. Thus, the rotational speed of the turbine
varies from 1900RPM to 3500 RPM. When the noise level varies from 21dBA to 41dBA,
and the air flow from the 12.0CFM to 22.1 CFM. By the way the size of the turbine are 80 to 80 mm, which exceeds the size of a similar turbine cooler Aero7 (70mm to 70mm).
Variable speed by means of variable resistance. For
ease of rotation shall be accompanied by a metal knob.
For the user it can be located either on the front or the rear
Now consider the radiator, which is completely made of copper
(Other than housing, which is made of aluminum and painted in the color of copper).
Next, we examined the method of fixing the edges and base of the radiator.
It is easy to see that the edges are glued to the ground with the help of a thermal interface.
And as we have repeatedly convinced (examples:
Thermaltake Volcano 11 Xaser Edition), such a method significantly reduces the effectiveness of
cooler in general.
Not pleased with the quality of treatment foundation – even and smooth, but a mirror
state it away.
However, for processors with a heat spreader (heatspreader)
quality of the base is no particular significance.
And finally – do not like mounting the cooler. Due to the fact that the turbine
is large, fastening clips have a small move and install them uncomfortable.
Now look at the performance.
To test the effectiveness of the new cooling fan was assembled the following system:
As the enemy appeared cooler Zalman 7000Cu, which is by far the
one of the best coolers. CPU temperature and fan speed were measured
program Motherboard Monitor v126.96.36.199. For 100% CPU used by the program
BurnP6 (running two instances of the program).
Thus, the results:
At maximum speed, the cooler is CoolerMaster Jet4 showed average results:
gap between the cooler Zalman 7000Cu at 4 degrees C. Also Jet4 greatly outperformed its competitor in terms of noise. If, at maximum speed, the noise of the cooler Zalman 7000Cu well tolerated and is dissolved in the noise of other system components (video, power supply, hard drives), then Jet4 noise is much stronger and overrides all other sources of noise. The situation is exacerbated at minimum speed: Zalman 7000Cu operates silently, and the noise CoolerMaster Jet4 it is possible to hear (21dBA – according to the manufacturer, in my vzglyadsluh more noise at 1-2dBa).
Summing up: without a doubt cooler CoolerMaster Jet4 is the most stylish and beautiful cooler
who visited us in the laboratory. It can be safely advised to fans of various modifications,
owners of buildings with transparent windows. Also Jet4 – it is an ideal candidate for the gift.
But for serious overclocking cooler does not fit – all the fault of the relatively low productivity.
It is worth recalling that the Zalman 7000Cu not the most efficient air cooler. For example
Thermalright SP-94. In addition, the output is very hot processors on the Prescott
much stricter requirements for cooling.
It is also difficult to recommend a cooler fans of silence because even at the minimum
speed can be heard. As for the size and weight of the cooler, it does not match
specifications for Intel (though the same problem and Zalman 7000). And the last – the price of the cooler
online stores is
about $ 37, which in my opinion quite expensive.
The presence of the original illumination.
Designed for Intel Pentium4.
Elevated levels of noise.
Several inflated price.
