    need some help with fans and display of the ryujin 240

    hello all,
    i just built a new rig and went with mostly asus and and amd this time. (last time i went amd was over 20 years ago).

    My hardware;
    motherboard = ASUS AMD AM4 ROG Strix X570-E Gaming
    CPU = AMD RYZEN 9 3900X
    CPU cooler = Asus ROG RYUJIN 240 RGB
    Graphics = ASUS AMD Radeon RX 5500 XT
    ram = G.SKILL Trident Z Neo (For AMD Ryzen) Series 32GB x 2
    fans = Antec Prizm 120mm
    case = NZXT H510i

    so far everything is fine other thatn an issue i'm having with my AIO cooler. first it took me a while to figure out what was making the loud fan noise. turns out it's the fan over the cooler heat sink.
    it took me a bit to figure out the fan as ai suite 3 has,
    1. aio pump, (with a question mark) set at full fan speed
    2. w_pump, (with a question mark) set to full fan speed.
    3. rog ryujin fan, think this ios for the 2 fans on the rad
    4. rog ryujin fan 1, this is the fan over the heat sink wich i can lower to make the fan not soi loud.
    5. chassis fan 1, top fan (works great)
    6. chassis fan 2, back case fan (works great)
    so i was thinking each fan ai suite would be better lableled as it's all asus, plus why do i have a reading for aio and water pump?
    also i have cpu temp and fan speed set in the ryujin display, but i never see the fan speed it's always zero. even when i can hear the fan it still shows 0.

    now if the system goes to sleep, the fan in the aio cooler above the heatsink gets loud again, if i log in it continues. the only way to stop it is to open ai suite 3 and change the fan curve then hit apply. when i say loud, the fan sounds like it's reving, like the fan is going from low to high pretty fast.

    hope this makes sense and someone can offer some advice.

    Right. So that little fan is loud right? That seems to be a common complaint. You can adjust it.

    I have the 360, but my case fans crank out a crazy amount of airflow (Noctua fans), I have literally taken the glass panel off the front of my case so that there is nothing impeding airflow and I have Turbo versions of GPUs which move the heat outside of the case.

    That said, you might want to watch this video starting at around 20:30.

    This video should help too--go to about 9:00:

    Also there is a page for the cooler, and you want to be sure you have the latest firmware from it.

    Hopefully this helps.
