Thermal performance with 4x180mm fans
For the test of the thermal behavior, the system had to run through the same course as with the stock configuration: 30 minutes of Cinebench R23, followed by 30 minutes of Furmark and then 30 minutes of Red Dead Redemption 2 (endurance run through Saint Denis).
Of course, the test system is also identical
As always, all fans were running at 60% of</x-1> their maximum speed. In addition to replacing the three 140mm on the bottom with two 180mm Prisma fans, one of the replaced 140s was mounted as an exhaust in the rear of the case.
Grey = Stock @ 60% PWM
Green = 4×180 + 1×140 @ 30% PWM
Blue = 4×180 + 1×140 @ 60% PWM
As you can see, the change from 3x140mm to 2x180mm at the bottom has changed the temperatures only minimally. Out of interest, I also ran the configurations with the four 180 fans through the course at significantly lower speeds and achieved only slightly worse values with significantly lower noise than with the high-speed standard equipment.
Some users had feared that the power supply would heat up more than average due to the positioning under the lid, as it contributes a significant part to the warm air being transported out of the case. I had this concern as well, even when I tested the Antec P120 Crystal a while back. In fact, in the actual test case with the air-cooled CPU, I could not detect any excessive heating of the PSU, because most of the rising heat is directly transported out of the rear of the case by the CPU cooler before it even reaches the PSU. Unfortunately, due to lack of time, I was not able to validate whether this changes significantly when using water cooling. However, I’ll go out on a limb and say that thanks to the good airflow of the case (and when using an Exhaust fan in the rear), the PSU is not so heavily loaded even when using water cooling that it suddenly mutates into a hairdryer.
