Cougar Airface Eco RGB: Cougar promises more eco-efficiency through many holes 47 comments
Image: Cougar Gaming, background changed
With the Airface Eco RGB, Cougar introduced a housing with a launch front, numerous dust filters, an Argb hub and a removable cover. It is advertised by the manufacturer as an eco-efficient footprint because it should be particularly effective at cooling, thanks to thermodynamic principles – but the explanation is thin.
A forehead like cheese
At first glance, the viewer of the new Eco RGB from Cougar Airface sees a variety of holes, strictly speaking 171 pieces, on the front, which should provide fresh air. By default, Cougar installs two 180mm PWM fans. The fans can be illuminated via Argb, as can the pre-installed 120mm fan on the back. However, the latter must do without PWM.
Due to the perforated front, there are relatively wide bridges around the fans around the holes around the holes, which impedes the flow to the fans. The holes also have a larger diameter outward than inward, so a cone with rejuvenation is created inward. Cougar advertises this as “thermodynamic principles,” which are intended to increase efficiency and reduce environmental pollution and the ecological footprint of housing. The animation and description make it seem like more air could be promoted with the same performance.
The Airface eco RGB was developed with a focus on eco-efficiency. The bowling-shaped ventilation slots are rejuvenated with a wide inward opening and use thermodynamic principles to optimally utilize airflow through the front panel. Added by two 180 mm PWM fans, which maximize cooling without additional energy costs, environmental pollution and ecological footprint are reduced.

What principle should work here?
The diagram published on the product’s website speaks of an effect that would be a benefit for cooling through interior hole rejuvenation. It is more likely that the front type will be more impeded by free flow to the fans than would be the case with a mesh front. Mass maintenance also applies here. As a result, the air mass flow in the holes at the inlet, with a larger diameter, is the same inside. The air also cannot dissolve in air, the escape remains forward: higher flow speed at the narrow point. This can lead to higher noise development and more work for the fans behind, who have to overcome the pressure loss on the holes and thus a reduced volume flow. It remains debatable how it is to achieve higher efficiency in air channels and also in comparison with the operation of this more efficient operation. Additionally, fan power consumption typically moves into the single digit sludge range, smaller savings here would not be a significant factor in saving electricity anyway.

It must be dust-free inside
The case has a dust filter on top, which holds onto the case via a magnetic frame. The power supply area has a dust filter which must be removed at the back and the dust guard at the front can be removed from the left side for cleaning. In total, the housing can accommodate seven fans in sizes from 120 to 180 millimeters, with larger fans reducing the number accordingly. For water cooling, radiators in sizes 120, 140, 240, 280 and 360 millimeters can be assembled on the front and in the cover. If a 360mm radiator is installed in the cover, there is no space for another size in the front and vice versa.

Four hard drives and a practical cover
Inside there is space for two 2.5-inch and two 3.5-inch hard drives, the latter in the power shaft. Graphics cards can be a maximum of 390 millimeters long and a CPU cooler no more than 190 mm high. The feed of up to a maximum of 200 millimeters can be assembled in length. The cover can be removed for simpler assembly, so the entire left side and cover are accessible, without corner braces.
The I/O panel can be installed either on the front of the cover or on the bottom of the stand. It houses the RGB and power button as well as two USB A sockets, a USB-C socket and a 3.5mm combo jack for headphones. On the right, behind the main board, there are numerous assembly options for cable management and an RGB hub with six caps for organizing lighting centrally. The housing is available for around $110 in two colors, black and white.
