Zotty. I have 9 LL120 fans (three 3x packs), 3 of those being attached to the radiator for my H150i Pro. I also have 2 RGB Fan LED Hubs and a Commander Pro.

You have to create your own profile to do so. Hit the + sign and create a new profile and then you will have options. The 3 there are static set by Corsair and can not be changed. Not yet but the presets dont change the speed like they should the stop at 1110 ish Rpm on all 3 settings. Moderator. The pass through is not to sync them. The pass through just takes 1 usb header and splits it into 2 headers. For all intents and purposes it acts like a second usb header on your motherboard. you can use any device that uses it. Even add actual usb 2.0 ports. its only there to let you add a commander core XT even if you only have 1 usb header Using a usb 3 to usb 2 internal adapter and the nzxt usb 2 hub i manage to have all 4 commander xt working, I left my 2 commander pro plugged on the motherboard usb 2 headers. The cable management is a bit more clear as the commander core xt replace at the same time a pwm hub, a lightning hub and a lightning node pro. Open the iCUE software.

Drag and drop the fans in the preview image in the correct Take Fan 1 and put it at the end, move all of them up. 1 bad fan can take down the rest of the chain. So it's like finding a bad bulb in a string of Christmas lights. So what I did was put one in port 1. Then placed each one in port 2 to see if that worked. Nothing worked in port 2. Solution for Corsair CPU Pump: In your bios setting, make sure that the CPU fan/pump is set at max speed. Without it being set to max, upon start up, windows will "underload" the pump since the CPU isn't hot and cause the CPU pump to temporarily lose power. When it is set to max, the pump will continue to operate without the risk of losing Posted April 5, 2021. Hello!
