Thank you for the ideas and additional troubleshooting steps. I was running out of ideas. I'll swap the front 4 ML Elites to be connected to the controller and swap the 3 AF Elites to the PWM Hub and see if the sound is present. I've watched a few youtube videos of the humming ML's make and the sound mine are creating is similar but louder. I noticed a difference upon close inspection of all of my ML RBG Elite Fans. My bottom two ML 120 RBG Elites on the Front of the case are spinning slightly differently than all the rest. The center of the front 3rd and 4th fan appear to be wobbling. All screws are tight and I cannot physically move or shake the fan housing so I believe they appear to be mounted well. I tested each fan individually and confirmed the the two fans that are wobbling are indeed the two fans creating this sound. It appears the fan blade is wobbling on the base. Could this wobble have something to do with the sound? The sound started within the past few weeks and I hadn't noticed this wobble before the sound. Corsair 7000D Front of Case – 4x 120mm Corsair ML RBG Elite fans - Intake - This are the fans creating the loud humming. Side of case – 4x 120mm Corsair ML RBG Elite fans – Intake - Completely Silent Top of Case – 3x Three AF RGB ELITE Series PWM 120mm fans – Exhaust - Completely Silent Back of case – 1x ML 120mm RBG Elite fan – Exhaust - Completely Silent Controller Config Commander Pro – 4x 120mm Corsair ML RBG Elite fans - Connected to PWM Hub then Hub PWM Connected to Fan 1.

Current Fan Config and Layout 9 ML 120 RBG Elite (SKU CO-9050113-WW) 3 AF120 (iCUE H150i ELITE CAPELLIX XT) 3 AF120's - Commander Core 4 ML120's PWM Splitter supplied with the 7000d. PWM header connected to Fan 1 on the Commander Pro 5 ML120's connected to the Commander Pro. 1200W PSU Commander Pro and Core connected to different Sata Power Cables The 4 ML120's on the front rail of the case are making a humming electrical sound. This sound is only present between 300-900 rpm. Above that the humming stops and changes to general fan noise at 1000rpm+. I have a Seasonic Vertex GX 1200w PSU and the commander core and the commander Pro are connected two different SATA Power Cables. I prefer the front 8 ML 120's to sit between 600-800rpms and the rear ML 120 to adjust per AIO Coolant Temp. My temps are pretty good with Ambient at 23c, Idle 28c, Load 34c Since I haven't been able to recreate the issue it has made troubleshooting an interesting process. I've read previous post about the ML 120's and the sound they normally make when running however since only 4 out of the 9 fans make this sound when this is occurring I'm not sure. The three possible I've come up with are. 1. The fans are dying and need rma. 2. Issue with ML120's on the PWM Splitter. 3. Power delivery issue in my power config. I picked up a Core XT yesterday and plan to swap the Pro for the Core XT and see if the sound continues. If it does I'd like to use the Core XT / Core / Pro all at once but due to the Asus Z790's USB layout I'll have to get a internal USB hub to use all three but I've read conflicting reports on Internal USB hubs and using multiple controllers.

Thank you for all the responses and assistance. For now I picked up a iCUE H150i ELITE CAPELLIX XT for peace of mind until support gets back to me about the LCD screen.

I also just had QUE force the firmware update on the Commander Core and the pump speed sensor starting showing again in the dashboard but it may just be a glitch since its not changing at all and its reading duplicate fans.

I was gonna swap the boards anyways so I figured it won't hurt. I do wish that I could everything rewired in one go though. I haven't seen any warning's from the CUE software about a pump fail at all. My coolant temp is 29-30 idle and 33-34 underload with fans at 800rpms so it appears the pump is working ok. I can even see my coolant temp just not the pump speed and pump setting. I thought maybe it was the wide cable connection to the commander core but feeling the click when I push down and looking a picture someone posted in the H150I post makes me think its in all the way. I ordered a cable some others have tried so I could connect the USB off the pump to one of my external USB slots to see if that makes a difference. Probably not but at this point worth a try. I posted some images of my QUE and windows appears to detect the LCD screen.

I have the commander core and a lighting node pro. The commander core usb and the pump usb were connected directly to the motherboard. I only set the RBG with the lighting pro in the beginning and then disconnected it. I wondering if new commander core (non xt) that I installed did make any difference then that would indicate something with the LCD screen unit or the wide cable coming off the LCD housing unit. When I originally bought this unit it was the only AIO in stock within my area that had the LGA 1700 bracket. My PC sits on my desk and I can't see inside of it. If I could just delete the LCD Top and connect the pump to the commander core I definitely would. So the pump showing up in IQUE is reliant on the USB and the LCD screen working is reliant on the wide cable if I'm following correctly. I tried both usb ports but no change. The LCD screen shows the corsair emblem and will change to the red triangle or it will show the corsair emblem change to the 0 degree coolant screen then change to the red triangle. I've had the pump disappear out of IQUE before but reinstall of IQUE has fixed that issue before. My motherboard is a Asus Z690E which seems to be issue with this AIO. I have a Asus Z790e as well that I plan to swap in soon.

Thank you for answering my question The pump is running and even with a game running my temps are good. I had the pump set to Variable mode before this happened. I have access to change my fan settings on the commander core at least. I'm not sure if the pump is running off my last config or if it is in a default setting but so far it seems ok without being controlled. I forgot I had another Commander Core brand new in box with a H115i I had purchased for another machine that I hadn't built yet and compared the two. Both looked the same and the wide pin connection appears to be the same. I connected the LCD head to the new commander core hoping that was the cause but still the same results. Appears the issue is the LCD screen itself or the wide cable. I tried reseating the Wide cable into the commander core and felt the click like I had before. I haven't been able to find pictures showing how far exactly that wide cable should be in the commander core so I'm not sure. The usb that comes off the pump what does it do exactly?

Will both the Core and Core XT work or just the Core? I was thinking of buying on for testing and reuse it later on for another build. 2. Is there way a way to control the pump as it is right now. The pump is annoying loud right now.

Yesterday my H150i LCD started showing the Red Triangle and the Commander core was displaying instead of the AIO. I've done all the troubleshooting below and nothing has worked. This AIO came with a commander core and I see the commander core XT are out. Can either the Core or Core XT be used. I submitted a ticket however I may buy another core and see if that fixes the issue. My motherboard USB's are both working and from all the troubleshooting I've narrowed the issue down the the 24-Pin Cable and the Commander Core. I can tell the pump is running right now due to its annoying hum and my temps are good. Anyway to lower the pump from what I assume is 100% that its on right now?

I bought a new bought a new case and I'm trying to figure out how to best run the fan cables. I will have 8 ML 120 RBG Elite fans (4 Front, 4 Side) a H150I Elite (3 Fans Top mounted) and 1 rear ML140 RGB Elite. I've read some other posts and I plan to connect the front 4 fans to my Commander Pro and the 4 side fans and rear fan to my commander core. The top 3 fans for the AIO will connect to the included PWM Splitter that came with the case and that will connect to the command core. I've quickly realized that I need at the very least a few PWM Extension cables. Are there any recommendations for good PWM Extension cables vs whatever has high ratings on Amazon. I've seen the posts about the RBG extension cables and will get those for the front 4 fans. I'm try to prevent a rats nest with the wires and I think the extension cables are the key.

Ok thank you for all your help. I will test and see which produces better cooling for the gpu.

Thank you for your response. The front fans in the push/pull are doing well at about 1000-1200rpms. Gaming my temp CPU is around 40c and my coolant temp is 33. GPU stays around 63. Would it be better to have the top fans as exhaust instead of intake? From when I looked at the cases airflow originally the air was designed to move through the front and out the top and back.

I finished with my build and now I'm trying to balance sound and cooling. I have a push/pull config on the 360aio with 6 of the ML 120's RGB fans. Two ML 140 RBG fans as intake on the top and one ML 120 RB as rear exhaust. My temps are doing well with 50c being the highest on the cpu under load. Water temp under load is 32-34c. I haven't done any overclocking and the Asus boost in the bios is turned off. The two ML 140's keep revving up with the balanced fan curve preset. I created my own and pointed it at the liquid temp on balanced and they stay around 1500rpm but climb eventually. What would be a good fan curve to accommodate these fans? With one rear exhaust and the rest of the fans intake, I believe I have a good positive air pressure to reduce dust. Would an ML 140 be better on the rear for exhaust? I feel like the ML 120 may not be enough for the exhaust. I've always just had all fans on balance in my old build so creating the curve is new to me. I want everything to be cooled however I also don't want to hear the fans over my headset so I'm trying to find the balance. Ambient room temp is 21c.

I ordered the stand off screws for the LGA 1700. I had the h115i already never use it and plan to use it for my new build with an i9-12900k and Asus ROG strix-e. Will the brackets that come with the h115i be able to work with the LGA 1700 board or is there actually a specific bracket.

I want to replace the CPU in my build and upgrade the motherboard and ram while I'm at it. With the AIO I already have (new in box) would the ram fit? On the chart it says low profile for the top mounted option. I don't think it will but wanted to check for opinions. I've also already ordered the standoff screws for the 1700 as well.
