Temperature behavior
Now we come to the temperature behavior. As already teased in the build diary, I had to carry out several tests in the SUP-01 and observe whether this case would also disable the heat pipes of some cooling solutions thanks to its unusual mounting position. And – surprise! – once again there were unfavorable temperatures and a lot of fan speed to marvel at.
Test system:
The well-known B550 platform with Ryzen 9 3900X was once again used as the test system. This system may soon be replaced by a modern AM5 system. The 360mm AIO supplied by LIAN LI was used as the cooling solution for the CPU and different graphics cards were used.
| CPU | AMD Ryzen 9 3900X PBO on |
| CPU cooling | LIAN LI GA II Trinity 360mm AIO |
| Mainboard | GIGABYTE B550 Vision D |
| Memory | THERMALTAKE Toughram 32GB DDR4 3600 |
| Graphics card | KFA2 GeForce RTX 3070 Ti SG |
| SSD | HP FX700 M.2 2TB |
| Case fan | LIAN LI GF.12Q1K0 120mm x 3 |
| Power supply | DEEPCOOL PX1000G WH 1000W Gold |
General conditions:
AIO/CPU fan: 900rpm
Case fan: 900rpm
Pump: 2200rpm (min)
Room temperature: 21.1°C
CPU Torture
For the CPU stress test, I again used Cinebench R23 in continuous loop. Almost the entire test was over 140W and an allcore boost of ~4050-4075MHz could be maintained (PBO on). The average temperature of the 3900X was 77.5°C – a very respectable result!
Gaming workload “Attempt 1”
Borderlands 3 was again used for the gaming test, as it practically fully utilizes the graphics card throughout and therefore generates a lot of waste heat. The positioning of the AIO including the exhausts in the same chamber also has a very positive effect on the temperature of the CPU, which was very constant in the low 50°C range after the game started.
The most interesting thing, however, was of course the behavior of the graphics card and at this point the disillusionment was great again, because the 3070Ti SG once again did not like the upright installation at all. Shortly after starting the game, the temperatures on the GPU were already around 80°C and the GPU hotspot was just under 100°C, with turbine-like 3000rpm GPU fans. I put an end to the tragedy after a few moments.
Gaming workload “Experiment 2”
For the next test, I placed the case on the glass pane to simulate a vertical installation of the graphics card, but upside down, i.e. with the PCIE port facing upwards, without obstructing the air supply and exhaust of the rear chamber. Yes, the hot-headed 3070Ti with its ~300W wasn’t exactly cool and quiet here either (2200rpm fan speed), but at least the temperatures were within limits and the hotspot barely climbed above 90°C over the entire test run:
Interim conclusion
Basically, the CPU temperatures in the SUP-01 can be described as rock solid, at least when using a complicated AIO cooling solution. Good results can be achieved thanks to the outsourcing of the radiator with direct dissipation of the heated air. In addition, the pre-assembled case fans are also quiet up to a speed of a good 800rpm and do not generate any significant bearing noise.
It is a pity that this orientation of the graphics card has been chosen, because as already feared, many cooling solutions (depending on the orientation and shape of the heatpipes used) do not cope well with hanging or upright mounting. And in this case, even the good air supply and the low temperature inside the case unfortunately no longer help.
