However, rendering on the GPU, average GPU dT was 29.2. Relative to other cases, it fared better than it did in Firestrike, but still not enough to compete with the two be quiet! Cases. It did cool better than the Meshify C and Define C, though, and it beat the Enso by 3 degrees. This teaches us that the Define R6 primarily starts struggling with GPU thermals when both the CPU and GPU are under load, as it doesn’t have enough pathways for hot air to escape the enclosure. Fractal R6 Noise Levels The front is made of brushed aluminium throughout, except for a small recess at the top in the middle, which releases the lower part of the white LED of the Power Button. The front is a door that opens to reveal a blind-like screen with the first of a total of three dust filters. The screen can be removed with a handle on the top. Behind it are two of the three pre-installed fans. Fractal Design has opted for 140mm fans that draw in air through side inlets that are located in the frame around the front door. Alternatively, three 120 fans can be installed here. The fans can also be replaced with correspondingly large radiators. The frame itself is made of plastic. The hinges of the internally insulated door can be placed on the right or left side. All you have to do is remove the screws of the hinges on the door and reposition them. Easily Accessible I/O panel
In standard layout(storage layout), you'll only be able to fit a 240 or 360 mm radiator. The 240 mm radiator will fit without any restrictions, but with a 360 mm, you would have a maximum motherboard component height of 36 mm. This mainly is affected by the motherboard I/O-shield, big VRM heat sinks, and RAM, so I'd recommend having low-profile RAM in combination with the top radiator. 280 and 420 radiators will not fit in this layout. Replacing the AiO with a CPU tower cooler and attaching two more Corsair fans to the lid made hardly any changes. It should be noted that these observations were made during the heat wave of the last few days – a test of endurance, so to speak. We tried the AiO at the front and a vertical airflow with two fans at the bottom and two at the lid. In the end we came to the conclusion that a horizontal airflow with the AiO on the lid is the most effective structure. Load testing is conducted using Prime95 LFFTs and Kombustor “FurMark” stress testing simultaneously. Testing is completely automated using in-house scripting, and executes with perfect accuracy on every run. In my situation, the ambient noise almost always is what I hear - not any fan noise from my case. If I am really tasking my computer and the FD fans ramp up in speed, typically by that time my CPU, PSU and GPU fans have ramped up speeds and sound levels too - not to mention Led Zeppelin is a few dBs higher too! OK, mourning over. This Fractal Define R6 review looks at build quality, thermal and acoustic performance, and cable management features. This enclosure is one of the few to impress us in the last few months, given the prevalence of cases like the Bitfenix Enso, and we found the R6’s build quality to be even better than the already-liked Define/Meshify C.Prior to load testing, we collect idle temperature results for ten minutes to determine the unloaded cooling performance of a case's fans and air channels. Thermal benchmarking is conducted for 1400 seconds (23 minutes), a period we've determined sufficient for achieving equilibrium. The over-time data is aggregated and will occasionally be compiled into charts, if interesting or relevant. The equilibrium performance is averaged to create the below charts. According to the instructions, the 5.25-inch slot must be omitted in the open layout. Nevertheless, we managed to install a Blu-Ray player without any problems, even with a subsequent 280mm radiator on the upper side, even though the optics aren’t flawless anymore, because the DVD drive is then visible through the transparent side panel.

Rendering our blender test on the CPU, average CPU dT was 36.9. That’s cooler than any case we’ve run that test on except the Silverstone RL06, including the DB Pro 900 and DB 700. The R6 is definitely capable of keeping air-cooled CPUs at safe temperatures under load.
The front panel is now magnetic on the Define 7 (not a big change TBH) and the 5.25" drive bay in the Define 7 has a small dust filter instead of a plastic cover and allows for fans to be shifted "up there" meaning the front now supports maximum 3*140mm instead of 3*120mm as it was on the R6. If you believe your FD fans are making too much noise, try using the R6's fan controller to reduce rotation speeds. Watch your temps to make sure they don't increase too much. I recommend you also verify any fan noise you are hearing is really coming from the case fans, and not the CPU fan, GPU fan(s), or the PSU fan. You could easily replace your case fans only to find out the fan noise was really coming from the PSU or something else. And if using water cooling, note pumps can make a lot of noise in comparison. For AiOs with fixed connections, this is likely to be extremely difficult, if not impossible, due to the limited height. In addition, the recess for the power supply unit is considerably narrower than 140 millimetres, which is why a 120 millimetre wide radiator without connections, which must also be fitted with fans beforehand, can pass through without much fiddling at most. To ensure that the cables for the power supply have enough space, the radiator must also be pushed all the way to the front. Only then can it be connected to the water circuit through the recess. It may then collide with another radiator on the front. In the open design, i.e. without the drive cage, a 120 mm or 140 mm radiator at the bottom of the front panel or better a compensation tank as part of a custom water cooling system fit stress-free in the open design.
