Temperature behavior
I had already announced that I would no longer strive for comparable results in this area of my case tests due to frequently changing hardware and coolers. Instead, I will only judge the general thermal behavior in the future: how the temperatures are to be judged with the present system, whether there is a heat buildup and how loud (subjectively) the pre-installed fans run.
Test system
The familiar Ryzen platform was used as the test system, although a larger graphics card was used this time and an AIO was used instead of an air cooler.
Framework
- 20.5°C room temperature
- Case fans fixed at 500rpm
- AIO fans fixed at 500rpm
- AIO pump fixed at ~2400rpm
CPU Torture
The Cinebench R23 was used for the CPU Torture Test in the loop. 30 minutes to warm up the cooling water and then another 30 minutes with monitoring. For the frugal APU, the 360 AIO is of course absolute overkill despite overclocking. Thus, the CPU had an average temperature of 60°C under full load, while the pump and all fans whirred quietly at minimum speed. The radiator mounted as an exhaust in the lid transports the heat generated by the CPU and the voltage converters directly out of the case, which keeps the temperatures inside the case very low.
Gaming
Red Dead Redemption 2 was again used for the gaming test. The game utilizes the graphics card well with high settings and also hammers the small quad-core properly. Because the 3070 Ti draws a senseless amount of power out of the box, I undervolted it a bit so that it was content with a reasonable 220W over the entire test period. I had also allowed quite a while for warm-up before this test because the waste heat from the graphics card would definitely affect the coolant in the radiator in this scenario. After a good half hour, the temperatures settled down and I started monitoring. The pump and case/radiator fans also ran at the minimum speeds listed above in this test, because I regulated them depending on the CPU temperature and it didn’t even exceed the limit of 55°C. The graphics card also stayed pleasantly cool at 66°C, although the three small fans were already clearly audible at around 1600rpm.
Interim summary
The airflow works very well in the Ceres 500 thanks to generous perforations and decent fans. The fans used are pleasantly quiet at low speeds and already provide a clearly noticeable airflow in the case from 700rpm. At the beginning, the bearing of one fan was slightly audible, but that was completely gone after about 2 hours of runtime. At idle, or as long as the graphics card fans did not start, the AIO’s pump, which is fixed at minimum speed, was by far the loudest element of the cooling circuit.
Overall, I have had so much fun with this “build” that I have considered transplanting my main system into this enclosure. There would even be enough room in the Ceres for the custom loop with 420 radiator.
