4000x + h100i Elite Capellix [ BEST AIRFLOW CONFIG]

Recommended Posts

hello good evening everyone
I am building a new PC with the following characteristics.

Ryzen 7 5700X
Asus Rog Strix b550-A
970 Samsung Evo 1tb
1050ti (old Graphic card until I have money))
Aerocool KCAS 800W 80 Plus Bronze (also to change TBA)

Corsair iCUE 4000X RGB White
Corsair iCUE H100i ELITE CAPELLIX 240mm White
1x Corsair iCUE SP120 RGB ELITE 120mm


My original idea was to keep the 3 stock fans (black) on the front, in that same place.
Add full h100i (white) on top.
And the extra fan (white), in the back.

Original Idea:




But I am evaluating the option of mounting it as I have described it, but putting the cooling radiator on the front, along with 2 of the 3 (black) fans that come standard with the 4000X. [and adding my extra fan on the top]



I ask to know if they have experience between both mounting versions.
Also, if you want to add any modification, if you suggest another configuration, if you think something is wrong or whatever, I appreciate your correction.

All the best

PS: first PC that I assemble only with pieces from 0.

no worries 🙂

The second setup is better for the CPU. With the H100i on top it will be heated up by the RTX, but if you install it on the front of the case, it will have fresh air = cooler CPU.

Also, on the spanish post you mention varying the fan speed based on processor temperature, but that's not the best way to do it.

The fans should be controlled by the water temperature instead. As long as the water temperature has not risen, there is no need to speed up the fans. it will do nothing.

The water will slowly absorb heat from the CPU, and the radiator only needs to cool the water.

It's a bit unusual when we are used to aircooling 🙂 but the fans cool the water... the water cools the CPU. so, fan speed controlled by water temperature.


It is also more silent, because the water warms up slowly, so the fans accelerate, and decelerate slowly.

If you control by CPU temperature, the fans speed up and down all the time

Finally I am mounting the PC with the second configuration (in process)

  • The fans that come with the 4000X have higher amperage than the ones that come with the H100i Capellix. And that I think means more power.
  • The airflow will be much better, getting lower temperatures for the internal components like GraficCard and improving the airflow.
  • And it also looks nicer, because in this way the refrigerator covers the "black" fans. And the Rog Strix motherboard is more visible.

    My question was if the fans next to the refrigerator needed a special controller, but I imagine that if the temperature rises, the power of ALL the fans will increase. I have spent more money on the case and the refrigerator than on the rest of the components :classic_rolleyes:

the fans attached to the radiator need to be connected to the AIO controller. If you can connect them to PWM ports 1 and 2, they will already work correctly, responding to water temperature changes.

you can connect the rest of the fans to the other free ports and set fan curves in icue after that 🙂

For the fans, higher amperage doesn't mean much. the performance will depend more on the blade shape and speed. It won't make too much difference using the case fans compared to the fans that the AIO came with.
