H100i Elite Capellix loud noise on quiet mode

Background information:


Corsair 570X case

6 LL120 fans

4x8 GB Vengence Pro 4000MHZ

H100i Elite AIO cooler

msi mpg x570 gaming edge


I recently purchased 6 LL120 RGB fans and had the desire of installing all the fans and controlling them all on the iCue software. I succeeded, but in the event of swapping the SP120s for the LL120s, I had to use the Commander Core instead of the RGB Hub and the SP lighting controller that came with the 570X case.


After swapping hubs, my CPU cooler makes a constant whirring noise on quiet mode. This sound was never present when I ran the setup with the SP120s and the RGB hub instead of the LL120s and the CoCore.


Wiring info:

CPU cooler is in CPU_FAN

All fans including the lighting cables are on the Commander Core. The RGB hub is not being use as well as the SP lighting controller but they are still installed, but I feel as though that would not contribute to the CPU cooler being loud.


Everything works and looks fine, its just the CPU cooler whirring louder than before.

Any help would be greatly appreciated.

The lighting hubs should have no impact on the pump mechanics at all. They don't even share the same voltage rail for power.


What is more probable is in working with the case you shifted it at some moment and a previously innocuous bubble moved up into the pump/CPU block. That kind of noise is generally erratic and can have gurgles. Try lifting the front of the case so the tubes out from the CPU block are a bit higher than pump. Hopefully this lets the bubble(s) escape back toward the radiator. Regardless, if the noise changes when you lift up, you know you are on the right track. If the noise is consistent in tone no matter the position of the case, then I am afraid that may be something else not easily resolved.

Powered on so the pump will help push it out and also allow you to notice if the sound changes in tone. Theoretically, it could work powered off but you will be guessing as to whether you were successful or not and this would probably involve a lot of boot./shutdown cycles. No need to do any crazy gymnastics. Just lift up the front 6 inches and listed for changes in tone.
