Review cooler CoolerMaster Jet4

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

Cooler Jet4.

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

registered trademark).

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:

Titan CU9TB/SC,

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 v5.3.4.0. 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

he loses

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.



Excellent appearance.

The presence of the original illumination.



Designed for Intel Pentium4.

Elevated levels of noise.

Several inflated price.

The average level of performance.
