Better Airflow Without Front Door
We observed that the temperature inside the case dropped up to five degrees when we opened the front door and removed the PCI slot bezels on the back. The front door can be completely removed to improve airflow, but the hangers on the door hinge frame are quite prominently placed and interfere with the look of the otherwise attractive front. In addition, the acoustic insulation, which is glued to the back of the front door, is of course omitted.
We simply replaced the fans – of course with RGB LED lighting. After all, we wanted to put the tidy interior of the Define R6 in the limelight. The Corsair HD-140s run at higher rpm, but unfortunately are also louder than Fractal Design’s HD-140s. Only then did the temperature of the graphics card remain within a reasonable range, but it still became too hot when doddling graphically more demanding games.
Heat Wave as Hardness Test
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.
Until we switch to custom water cooling for the CPU and graphics card, we make do with a table fan that blows air through the open door. It cools the feet at the same time. In any case, you should invest in more fans if you have strong hardware and make sure you buy a graphics card with efficient cooling. However, our construction should also sweat in other housings.
A Lot of Space for Radiators (With Reservation)
For a self-constructed water cooling there is enough space for radiators in the Define R6 – apart from the floor because of the already mentioned restrictions – especially in the open layout. Even with a slightly deeper 280 mm radiator at the front, a compensation tank with pump fits into the front recess of the power supply cover. In the standard layout, 120 mm wide radiators up to a length of 360 mm and 140 mm wide heat exchangers up to 280 mm fit simultaneously at the front and at the top. In the open layout there is even more space on the lid, a radiator can be up to 420 mm long. On the back side, both versions keep the width at 120 mm.
