We analyze the Corsair Carbide 678C chassis, a chassis that bets on silence, but that allows a great flow of air if we need it.
Users are demanding more and more extremely quiet chassis but at the same time functional. This trend especially in terms of YouTubers, audio or video editors and the like. For these types of users Corsair has developed a completely closed chassis that is highly silent. The Corsair Carbide 678C is a chassis with sound isolating panels, but also removing the covers has a great air flow. Something perfect for when we have finished editing, where silence is needed and we are going to start rendering.
General characteristics
A very important aspect in any good chassis worth its salt are the materials and for this chassis SPCC 0.8mm steel has been chosen. This allows a great acoustic isolation, at the same time that it confers a great resistance. It has some plastic elements, like a retractable top cover that isolates the sound. On the other hand, the left side window is based on tempered glass.
We are talking about a large chassis and it is that this Corsair Carbide 678C has a length of 549mm, a width of 239mm and a height of 497mm. Internally, this chassis has the ability to support E-ATX, ATX, micro-ATX and mini-ITX motherboards, so we can put any motherboard on the market.
Regarding the limitations of the components that we can install, this chassis supports heatsinks up to 170mm high, power supplies up to 225mm long and graphics cards up to 370mm long.
Cooling capacity
Being able to properly refrigerate components is vital. With the entire chassis closed, the only fan that performs a real function is the rear, the rest contribute little as they are limited in the ability to introduce air or expel heat, as long as the chassis is in silent mode.
The Corsair Carbide 678C chassis has the capacity to support two 140mm fans or three 120mm fans on the front. The upper area supports three fans, either 140mm or 120mm. The rear part supports a 140mm or 120mm fan indistinctly and the lower area supports two 140mm or 120mm fans indistinctly.
The front, top and rear area has a Corsair SP140 PWM fan that is logically 140mm. It can operate between 400RPM and 1200RPM, has an airflow of 73.1CFM, has a static pressure of 2.08mmH2O and a loudness of 21.9dBA.
If we want to mount liquid cooling systems, the front part supports 360mm or 280mm radiators. The top supports either 420mm or 360mm radiators and the rear supports 140mm or 120mm radiators.
It has dust filters on the front, top and bottom.
Expansion and storage
Corsair in the PCI port area has arranged seven expansion slots and also has two vertical slots. This is designed so that we can put the graph vertically and thus display it.
Regarding storage space, the Corsair Carbide 678C chassis has plenty of space for hard drives. We can find room for three 2.5 ”SSDs of the Tool-Free type (without tools). It has six 3.5 ”bays of which four of these are of the floating type. This allows them to have a little play and little interference with airflow.
Regarding the front panel, we must highlight that it has two USB 3.0, a USB 3.1 Type-C, jack for sound input and audio output, the reset button and the power button. We can say that the basics.
Loudness and temperature
The Corsair Carbide 678C features sound insulation on the top, right side and front panel to dampen noise. This is not free of costs and is that the air flow is noticeably reduced causing an increase in temperature. As is logical to have bad airflow betting on low noise, our hardware is hotter. The good thing about it is that when we need to start a video rendering, we can open the front and remove the top cover.
To prevent sound from escaping, the upper area has a plastic cover that can be easily removed and hides the space for the three fans. This allows a large amount of hot air to be expelled efficiently. If we open the front, which has a hinge, a lot of air enters, which creates a large air flow. At a given moment, we can open the methacrylate side, which is also hinged and thus we achieve rapid heat dissipation.
Conclusion
This black Corsair Carbide 678C is characterized by being highly silent. When we seek silence, the internal hardware suffers from an increase in temperature, as is logical. This is corrected in seconds by opening the top and front cover, dropping the temperature by 15-20ºC in seconds. Everything cannot be had as is logical. It is very designed for those who edit content for YouTube or stream. During that time the sound of the fans will not leak. When you finish or start rendering, open and go.
It is certainly a great design success by Corsair, since we practically have two chassis in one. In addition, with all the filters that it carries we can keep our equipment quite clean of dust.
