Corsair Carbide Air 740 review and test

Bigger is better: this is the slogan that Corsair used for the introduction of Corsair Carbide Air 740. This is a larger model in the Air series, which is characterized by the special division into two compartments. But is bigger better?

Although Corsair Carbide Air 740 is positioned as a larger version of the Air 540, there are clear differences in both the inner and the appearance of the cabinet. Since the housing at the moment but a decade is more expensive than its more than three-year-old brother, would the Corsair Carbide Air 740  can see almost as successor. Despite the larger size fits just an ATX motherboard.

There are few manufacturers who have taken over the two-chamber design of the Corsair Air Series. Therefore, we tend to look at the competition that is somewhat similar in size and price. The graphs you obviously get the Air 540 against, the spiritual ancestor of the Corsair Carbide Air 740. Measuring 34 by 41.4 centimeters and 51 come from the cabinet volume to nearly 72 dm³.

Corsair Carbide Air 740: Appearance

Although the layout is preserved in two compartments, the appearance of the cabinet has become somewhat eccentric. Many mesh holes for optimum air flow have always been a feature of the Air series, but the edges on the front and top sides now walk across almost the entire width through. In one of the ridges is a power button processed. That you can actually just a little bit depressing, although the design may suggest that it is a deep compressible button.

In the side is a large Plexiglas window handles, the left and right extends to the edge. The main gateway to your hardware includes hinges, which can be opened with a lever. Then the side as a door opens: do you want all the way from, you can lift it out smoothly and in the hinges. For us this is a much finer resolution than normal thumbscrews, which also calling luxurious.

The other side can only be opened in the conventional manner and is completely closed, an opening for the fan of your diet after. As at the front, there is provided a removable dust filter. Other ventilation holes as on the top and back, are unfortunately still open.

Back to the front, where we had not discussed the front panel. Obviously we find a reset button and two audio connectors, plus two USB 3.0 ports. Specifically, the LED switch, resulting in a 2-pin connector. If you buy there HD120 led fans to, you can change the light with this switch. Among the connections seems to be a kind of mini-bay, but according to Corsair there can be mounted even get out of VR accessory. This allows you to HDMI in a beautiful way through loops to the front of your closet.

Corsair Carbide Air 740: Internal cooling

If you remove the side panel, you radiate face a sea of internal space. It is no problem to install a big three-way SLI setup and substantial water cooling, although this is the first not interesting anymore since Nvidia Pascal generation. You can mount a motherboard to ATX format, around which is still plenty of space to eliminate the cables to the other room, thanks to the omission of 5.25 “-bays.

In that other room fit you include the power (in ‘standing’ position) and you can lose storage devices. At the top there is space for three 3.5 “drives, which you can install without the use of tools The sides of the slides are nicely equipped with vibration dampers The solution for the 2.5..” Drives is very special: you click the four drive trays on each other, as it were. Each tray accommodates one SSD, but we would not recommend you through the rickety suspension and the lack of rubber pads to place a mechanical hard drive.

The Air series is of course for proper cooling. Corsair also has the cabinet equipped with three fans 140mm format. It concerns the AF140L, which is not available through normal shops. In total there are seven positions available for fans of this size, and one more when it comes to 120mm fans. For water cooling is also space: on the front fits a 360mm radiator, front and bottom there is space for 280mm copies and back you might get a 140mm-wheel lost.

Now we are talking about dimensions: Corsair provides a maximum height of the CPU cooler to 17 centimeters, while our study show that 19 centimeters fits yet. However you come close to the vulnerable side window, which you probably do not want. The video card can be up to 33 centimeters long, which will fit virtually any map.

We are talking about a box of 160 euros, but additions such as a card reader or missing fan hub / controller. At this price we had actually expected such a perk.

Previously devised various test setups and tried and eventually arrived at a rather simple but effective and consistent test platform.

As is known, there are heat sources in each computer to ensure that the temperature inside the enclosure where they do not provide adequate ventilation. The biggest heat sources in a powerful PC, the processor and graphics card. Depending on the type can produce a processor without much difficulty from 90 to 100 watts of heat, and for new high-end processors that can even reach up to 130 watts. Are you going to overclock the processor, the consumption may rise significantly.

The second heat source is the graphics card. A modern high-end card has quickly given a consumption of 250 watts, whereas for specimens with two GPUs even may rise even higher. A reasonable processor and video card can thus together without too much trouble to ensure a consumption of 300 to 350 watts, energy which is almost completely converted into heat. This, together with the consumption of the motherboard, hard drive and optical drive and 400 watts soon comes into view.

In order to be able to produce a heat output of 400 watts stable and repeatable, we have chosen to work with two controllable or heat sources, each of 200 watts. The choice is thereby finally fallen on the use of professional 200W incandescent lamps. With an efficiency of less than 3% passes a 200-watt incandescent bulb effectively about 195 watts of heat, and in a very constant manner. Our test set-up, therefore, consists of a defective motherboard on which we have two screwed fittings, in such a way that one lamp is located approximately at the position of the processor, and the second at the location where the video card normally inserted into the system.

By one or both of the lamps to illuminate we simulate a system that almost 200, respectively, nearly 400 watts supplies it to heat. On the prepared board we have also mounted a temperature sensor by which we measure the temperature within the cabinet. After allowing to stabilize the temperature, we measure it at a load of 200 watts in order to simulate a mid-range system, and at 400 watts in order to mimic a high-end system. Both scenarios we perform with the case fans on 12 volts present in the enclosure and 7 volts. All measured temperatures are normalized to an ambient temperature of 20 degrees.

We test the noise production in a sound-proof box, in which all of the sound can be detected above the 17 dB (A). For clarity, standard ambient noise is about 30 dB (A). In the case we place a Scythe Mugen 2 CPU Cooler, Scythe Gouriki a 700W power supply and an old Hitachi 80GB 7200 rpm hard drive. We test every unit without turning the case fans, to determine the damping capacity. We test the total noise in the case fans at low speed (7V) and high speed (12V).

Corsair Carbide Air 740: Test results cooling 200 watts

So we do a total of four measurements. The first set is at a heat of 200 watts, the second one at a heat of 400 watts. Both sets we carry out with the fans running at low and at high rotational speed. We accomplish this by setting the voltage of the fans 7, 12 volts, respectively. When a case in the first set (200 watts) temperatures above shows record 30 degrees, we usually carry a second set of measurements 400 watts out. When temperatures exceed 40 degrees, we usually stop the test.

200W 12V

In our first test shows the Corsair Carbide Air 740  all equal very good cooling, even the air 540 is defeated, like all other boxes in this class.

Corsair Carbide Air 740: Test results cooling 400 watts

The second set of the four tests we do with a heat of 400 watts. Here it is thus much more difficult for the housings in order to dissipate the heat as quickly as possible.

400W 12V

Even with a load of 400 watts Corsair Carbide Air 740  performs best.

400W 7V

Let the fans run slower, then we come to our toughest test. The temperature is not more than 23 degrees: excellent!

Corsair Carbide Air 740: Test results noise

As always, the noise equivalent of cool results.

No fans

We test cases always without spinning fans, purely to see how effective they dampen sound. The damping is not particularly good – not unusual for a cabinet without soundproofing mats and lots of vents.

7V

The Air 540 was noisy at 7V, and this applies to a lesser extent, the Corsair Carbide Air 740.

12V

At high rotational speed of the housing is quite loud, but the Air 540 and Phanteks Enthoo Pro make more noise. The cooling performance was just plain better.

Corsair Carbide Air 740: Conclusion

Like the Carbide Air 540 is the new model mainly focused on cooling. At a somewhat lower noise level knows the Corsair Carbide Air 740 better cooling than the existing variant. The air tunnel principle again proves its potential when it comes to sheer cool effect. Makes the noise of a closet you little and you will build a thick system with great energy wasters in it, then it is a good option.

If you spend 160 euros on a case, you may regard us what to expect. Corsair is unfortunately not true. Thus, not all mesh grilles fitted with filters. We know cupboards half the price at which it is the case, so we certainly expect. Although you will assemble in this case probably not a cheap motherboard with a shortage of fanconnectors, a fan controller had also been a nice addition, especially since the fans at full power pretty noisy.
