I like decent aircooling solutions, as they do require little bit less experience in maintenance and construction. Basically you need to clean the fans, coolers or filters from time to time, but there is no corrosion. For some time i am also using Fury X with its AIO cooler - I have the one with more noisier pumps but it seems to perform well.
The case is Fractal Design Node 804
Asrock X399M fits there like this:
Both board and case therefore allow dual GPU configuration (if the cables are properly set, and PSU will allow that).
CPU, RAM and VRMs
If you check the TOP screenshot, you are looking at LEFT chamber.
Lets start with case fans. 4x NF-P12 PWM. These are older fans (were bit cheaper)
Front fans are set to intake, top front fan is intake, top rear fan is exhaust. Each intake fan (and one exhaust fan) here has a dust filter.
On CPU is mounted cooler NH U12S TR4-SP3
Its intake fan is NF-F12 PWM, exhaust is A12x25 PWM. On the back exhaust is mounted NF-S12 PWM. I would recommend to check the specs of these three fans. Short to say... F12 has high static pressure on low airflow, A12 has higher static pressure on medium and high airflow, and S12 has low static pressure and highest airflow. This ensures that air fed to CPU gets throught the cooler as fast as possible, and then out of the case.
Before i mounted S12 to the back of the case, the RAM modules on the left side reported 4-6 more degrees compared to those on the right. Once i fixed that, RAM on the "hot side" are reporting only up to 2 degrees more.
Zone to the right from the processor should have positive air pressure, GPU acts as a tunnel and everything to the left from the CPU should have negative air pressure.
If you want to mount the Fury X into this case, you can mount the Radiator on the exhaust in the right chamber, them pull the card throught cut-out in the center.
On rear.jpg you can check how its mounted and that the tubes are not stretching too much. (hm. i need to clear the dust out of radiator fan).
The thing is that GPU runs hotter by 10 degrees (in average tasks) than CPU, VRMs and other. This positioning keeps the heat out of reach of CPU. In order to compensate the exhaust, there is 12cm fan by Fractal design on the front-bottom.
Also you can see Corsair HX650w, taking air from the bottom, through air filter.
Powering the fans
In some cases I used Y-splitter cable to couple those fans, which are expecteted to perform at same performance level.
CPU intake and CPU exhaust fans are connected to mainboard independently.
Exhaust fans (S-12 and, top P-12) share Y-splitter.
Intake fans (top and upper front P-12) share Y-splitter.
Bottom intake fans (bottom P-12 and FD fan) are also coupled via Y-splitter.
As the thermal paste cured a bit (after week or so)...
Ambient temperature was 26°C at the time of measuring.
CPU @ 4000MHz
Prime 95 Small FFTs gets CPU to 68°C, RAMs to 38-40°C, VRM up to 50°C.
On Idle CPU can get as low to 29°C, RAMs to 28°C, VRM to 30°C
This was measured when case was closed. Fans were set to full speed in BIOS so the PC is not perfectly silent. However when i set it to be more silent, the noise of old Fury X pump becomes noticeable
