ZAMAN Posted April 14 Share Posted April 14 I originally had corsair commander pro with 3 sp140mm rgb 3pin fan. Commander pro worked really well with the fans. I had it set to custom curve where if a device got hot the fan would speed up etc. I recently bought corsair AIO (CORSAIR iCUE H115i ELITE CAPELLIX Liquid CPU Cooler) this came with it's own controller and 2 ML140 fans 4pin PWM. So I replaces the commander pro with this new controller. Now the ML140 fan works really well with device temperature like before but the Sp140 fans stays at high rpm and the costom curve i set doesn't work well. Can some one please help me understand where i am going wrong. Should I go back to commander pro and replace the new controller. Thats means more wiring and more work. Plus will the AIO work well with this commander pro? I would like to keep the new controller and have to sp140 fans work as it did before. Is that possible? I have attached image of RPMs from ICUE. Please help. Link to comment Share on other sites More sharing options...
LeDoyen Posted April 14 Share Posted April 14 The AIO can't work with another controller. it has a connector specifically for the AIO pump and is basically the AIO brains. It can't be replaced. Your problem is more likely to be that your SP140 fans are 3 pins DC fans, and not PWM. The Commander core on the AIO is a PWM controller only. If you plug 3 pin fans to it, they will run at full speed. You'd need to either use the commander pro just for those SP fans, since it can drive 3 pin DC controlled and PWM fans, or replace the SP140 with PWM fans. Since you have the commander pro already, you may try reconnecting it ? Link to comment Share on other sites More sharing options...
ZAMAN Posted April 14 Author Share Posted April 14 Thank you for this. Can i have AIO controller running at the same time as Commander pro. My plan is to use the commander pro just for the speed of the fans and use the AIO controller for RGB of all the fans and AIO. Is that possible?

LeDoyen Posted April 14 Share Posted April 14 yes, you just need to use two connexions to the motherboard. Usually, most have two 9 pin internal USB headers. One is taken by your AIO, if you have a second one, you can plug the commander pro to it. If you only have one header, you can get powered hubs to connect both controllers to the motherboard. They should be next to each other on the board if you have two. Maybe drop the model of your motherboard and we can look at the manual, it's detailed in it too Link to comment Share on other sites More sharing options...
ZAMAN Posted April 14 Author Share Posted April 14 Motherboard is MSI x570 gaming edge wifi. It has as i can see two USB header. One is being used by AIO controller and Another for LED strip controller. I am hoping there is another one hiding some where. If not what is my option? Thanks.

LeDoyen Posted April 14 Share Posted April 14 corsair LED strips? i don't see any on your iCUE screenshot so, maybe not.. If it's corsair strips, the commander pro has two RGB channels that can drive them. Otherwise you can use a hub like this one to have more ports : https://www.corsair.com/us/en/Categories/Products/Accessories-|-Parts/CORSAIR-Internal-4-Port-USB-2-0-Hub/p/CC-9310002-WW Link to comment Share on other sites More sharing options...

ZAMAN Posted April 14 Author Share Posted April 14 I now have tried connecting Aio controller to Commander pro usb now the 3 case fans are not working but Aio fan works. Main problem nothing much is showing in ICUE. Link to comment Share on other sites More sharing options...
LeDoyen Posted April 14 Share Posted April 14 the commander pro USB connectors are mostly not working usually.. well, personally i never managed to get anything to communicate with those. Also make sure the Commander Pro SATA power is connected, just in case. Link to comment Share on other sites More sharing options...
ZAMAN Posted April 14 Author Share Posted April 14 I really didn't want to spend money. But i now have two USB headers on MoBo. Does that mean i can have command pro connected to one and AIO controller to another. When i do that i don't get to see command pro devices. Can both be connected like this and working at the same time? Link to comment Share on other sites More sharing options...
Solution ZAMAN Posted April 15 Author Solution Share Posted April 15 I just want to say thank you for your help. At the end I managed to get the commander pro to work as well as AIO controller connected to two USB hubs on the Motherboard. Commander pro only controlls the 3 case fan speed with 3pin connector and working just as it should. The AIO is controlling AIO fans speed and controlling The RGBs on case fans and on AIO. One little issue with iCUE software that is not allowing me to change the rGB on the RAMS and keeps going to red. But i can live with that. Here is the finished image of my loved PC.

There should be a setting that allows Mystic Light/Aura to take control of the RAM lighting. You want that off, then will need to reboot the PC.
