Airflow :
Additional ventilation takes the form of three fans, two Thermaltake Riing 14 and Fractal Design Silent Series 12. The two 140 mm fans are mounted at the front for intake, while the smaller Fractal is mounted at the rear for exhaust.
CPU airflow, original ventilation then completed:
We start with the temperature of our CPU. We’ll keep the front and top of our test case. Let’s see if the airflow is sufficient to influence the cooling of the Ryzen 5 3600X.
Since the case has no fan as standard, the graph shows only two bars. Meanwhile, by default, our CPU is hotter than when mounted in rival cases. This is to be expected, given the absence of a standard fan.
Finally, mounting fans inside this 6500D Airflow, we get temperatures on a par with the competition, although the Dark Base 701 fares better!
Original CPU airflow ventilation without front panel or top :
In order to ascertain the limiting factor in the story (and to what extent), we remove the top covers while we remove the bottom dust filter. The aim here is to show the raw performance of the built-in ventilation… Or to see how well the case keeps the heat in, since there’s no basic built-in fan in this 2500X.
Although there is no standard fan, it’s hard to know whether the front panel interferes with fan airflow or not. On the other hand, it seems to breathe well, given the small difference in temperatures measured with and without the front panel and top panel.
GPU airflow, original ventilation then completed :
We repeat the operation, but with measurements taken on the graphics card. Here, we test with original ventilation, then supplemented ventilation.
On the graphics card side, we find something rather surprising: our RTX 3050 is maintained at the same temperature level in this 6500D Airflow as in a Dark Base 701 from be quiet! However, by default, the graphics card took little advantage of the airflow provided by the case’s basic ventilation. The front fan was mounted quite high.
By adding ventilation, the temperature of the graphics card is reduced, but not by that much. Did we position the fan too high? Possibly.
GPU airflow, original ventilation without front panel ortop:
We repeat the same test, but with the front panel and top panel removed. Let’s see how this affects card temperatures.
Once again, the front panel and top panel don’t seem to interfere too much with the case’s natural airflow. The difference is just under 2°C.
Insulation :
Here, we’re simply measuring the noise emitted by our configuration when we run the CPU and GPU cooling very fast.
As far as insulation is concerned, it’s a case in the middle of the pack, with 40 dB measured. For the moment, the Dark Base 701 is the model that fares best, with 37.5 dB.
Original fan noise:
This time, we measure the noise emitted by the case’s original fan. To do this, the configuration is run in idle mode ( CPU and GPU ventilation at minimum), while readings are taken successively at 5V, 8V and 12V on the case ventilation.
Without default ventilation, and with the fan speed of our graphics card and cooler set to minimum, it’s logical to have a noise level at the daisy chain: 30 dB.
To sum up:
Thermally speaking, by default, we have a case without fans, and it shows against the competition. There’s no doubt that the purchase of a fan pack should be considered to reduce temperatures. Fortunately, the mesh panels do not restrict the flow of air, even if, with full ventilation, we found the CG to be warmer than that of the competition
