I ended up going 5000d since the graphics card I got is pretty big (Zotac 3080TI Amp Holo and 317mm). I think I'm going to use it on the front to pull air in, and move the front fan that comes with the case to push air out the top, or maybe just spend the extra $70 CAD and get the matching Corsair Fans. I may be wrong, but isn't it generally advised to have more intake fans in than exhaust fans to avoid dust build up?
Yes, more intake than exhaust fans is recommended. The thing to keep in mind when using a AIO radiator as an intake is you’re pulling that hot air from the AIO radiator into the PC case before it eventually exits via exhaust fans. If the AIO is mounted as intake on the front of the case then you’re probably blowing that hot CPU radiator air on the GPU.
Will it really make a difference if you have good airflow in the case? Probably not, but as an engineer I like more optimized heat flow designs where the hot CPU radiator air immediately exits the case.
If I were building my own PC in the 5000D case with iCUE I’d go with one of three layouts:
a) 280mm AIO exhaust on the roof (only swap to 360mm AIO if you can’t fit the 280mm), 2x 140mm intake fans on the front. Side mounted 120mm intake fan in the bottom side slot. That gives us a little more intake airflow over exhaust.
b) Same as above with a 2nd 120mm side intake fan in the middle slot. Extra intake over exhaust airflow. Note: this lets you repurpose the two 120mm fans that come with the case.
c) Same as above plus a 120mm exhaust fan on the top back of the case. This brings us to 7 total fans, the iCUE hub only supports 6 fans, so use a splitter cable on the two side intake fans to run them on one hub port. The back top fan is catching the hotter air at the top of the case while still keeping positive intake airflow.
The front fans on a case will usually be the loudest users hear, though it depends on where your case is located. I’d much rather have two 140mm stacked intake fans vs three 120mm fans on the front.
