That makes sense. I'm extremely happy to get this resolved. Now i know for the future what to look for if this issue occurs. Thank you! I watched many reviews on the Lian Li PC-11 Dynamic case and finally pulled the trigger. It's my favorite case that I've built in so far. The panels come off super easy and it has plenty of room to work in. If you haven't bought the case yet, Amazon has it marked down to $119 (org $140). My future plans are a custom water cooled loop. I've only had AIOs in my builds. Corsairs' new Hydro series looks great and it will probably be what I go with. Plus, it keeps everything within the iCue Software ecosystem. Best of luck on your build and take care!

UPDATE: Problem resolved! It was the fan pin connection setting that was causing the issue. After changing the commander pro settings from Auto to 4-pin (since these are PWM fans as you noted in #1), it's as quiet as a mouse on bootup. I greatly appreciate the help throughout this process!

Hey c-attack, Sorry the delayed reply. To answer your previous post, I disabled fast boot and still encountered the issue. 1. I will need to review iCue again to confirm but I vividly remember the header setting you mention and know it is set to Auto by default. I'll try switch it to PMW to see if this makes a difference 2. When I created the temperature sensor fan curve for my LL120s (6 total), I set the fan speed to 500. Again, I'll go back through iCue to confirm the settings applied. As you noted in #3, I recall having difficulty the first time I tried adjust any of the fan settings. 3. The sensors seem to be working. I'm getting temp readings on all four. When I get time, my plan is to remove all four and try only one to see if this makes any difference. See if this link works, it's a short clip of what I'm experiencing: https://www.dropbox.com/s/cbtt6mbqftcdnl7/IMG_0638.MOV?dl=0

You are correct, the option I have to choose from is the Commander Pro (1) Temp 1. I went back to iCue and confirmed the Commander Pro sensor #1 was selected for temperature data. Also confirmed the setting was applied to each fan. Before shutting down, I uninstalled CAM which I thought might be posing an issue. Additionally, I found that AI Suite is not installed so this is not an issue either (Should I install this?). I shutdown and rebooted but still not luck. My next thought is to reset the BIOS. I did this as part of the troubleshooting steps Asus sent me (before making this forum account) but I did not have the profile setup like you recommended. While looking through Corsair's forum, I found another person had the same issue back in January. You provided them with the same steps and it worked which leads me to think it is a BIOS setting or something. What do you think?

Hi c-attack, Thanks for the reply. So I went back and added 4 sensors to my commander pro. Not sure if all 4 are needed but I did it anyway. I followed your instructions and created a custom profile/custom curve. The max curve rpm I set is 500rpm. For the sensor dropdown, I selected the #1 sensor on the commander pro. The temperature for all four sensors is between 23-26 degrees Celsius. I then clicked each individual fan to apply the new settings. Doing a system shut down and reboot, I experienced the same problem. Fans were at max speed up until I hit the post screen. I repeated the above steps for GPU temp and motherboard temp but experienced the same issue. Any other ideas?

Hi Everyone, Recently, I added 6 Corsair LL 120mm fans to my PC. Along with the fans, I purchased a Commander Pro and a Corsair RGB LED Fan HUB to control the fan speed/RGB effects in the iCue software. The Commander Pro is plugged into one of the two USB 2.0 ports on my motherboard (Asus Z390-A Prime). When I turn my PC on, all of the fans run at max speed until I reach the post screen, then return to normal speed. While this issue isn't the end of the world, it would be great to find a solution. I never experienced this with my 2017 build that used NZXT fans/NZXT Hue. I've set quiet/fixed fan curves in iCue but this does not help. At this point, I'm tempted to remove the Commander pro and plug the fans directly into motherboard fan headers. Any help would be appreciated!!! SoldierNerd
