I re-installed version 3.21.88 and unfortunately that did not seem to work. At this point, I am wondering if I should RMA the Commander Pro, as it really seems the issue is stemming from the tach pin on Port 4, as the issue persists no matter what I plug into that port; fans will not ramp up from 0RPM, or ramp down to 0RPM on that port, whether it is a split fan or not. All other ports are fine.

I checked into what you have said, and on each splitter, one of the fan connectors has 3 pins, and on the other it has 4 pins. That being said, is there anywhere I can download the previous release of iCUE to test and see if the update caused any sort of issue? That would allow me to eliminate the possibility at least since I upgraded around the same time the issues started happening (rig has been up and running for 8 months with no issues).

I've checked my splitters and they all seem fully functional. They are not Rosewill splitters from Newegg, they are JBTek I bought on Amazon. As I stated, if I swap from a split fan to a single fan on port 4, it still retains the same odd behavior. I believe it may have started happening when I updated to the latest version of iCUE (or it is just a coincidence in timing)

I was really hoping it was just a splitter, but I guess that would have been too easy. I can't quite remember when I upgraded to the latest version of iCUE, but it may have been in the past couple days so it could possibly be a bug with the current release. It does honestly seem software related, but I did submit a ticket so that an RMA option exists should I decide to go that route. I might mess with some custom fan curves and see what suits me. Honestly, the default Hydro X profiles have been perfect for me for the past 8 months so I never bothered configuring my own. Just for future reference, how are people integrating a power fan hub along with a Commander Pro? By splitting out the control pin and only plugging that into the Pro, while the other 3 pins are plugged into a powered hub?

I'll try that and report back. What is typically recommended for a setup with a large number of fans, 2 Commander Pros working in tandem? EDIT: Had a single fan on port 3, so I swapped ports 3 and 4 so only a single direct fan is on port 4. Sadly there is no difference. It adheres to anything but setting it to 0RPM (which is what Hydro X fan profile sets it to when the temp is below a certain threshold), so it just sticks at around 1000 RPM randomly, until the other fans start spinning per their profile. Once they do, it randomly starts working again. Ill attach the normal ramp-up of the other fans, and the odd behavior of port 4 at the same time as it normalizes (port 4 on top, port 5 on bottom)

Interestingly enough, everything was configured for Auto on the PRO, but I just tried setting everything to 4-pin PWM and no luck. I've been running this setup for around 8 months now with no issues until a couple days ago. I have occasionally seen light flickering on some of the fans before but nothing major. I tried swapping the splitter thats plugged into port 4 for the one on port 5, and the problem still seems to persist with whatever is plugged into port 4, so it really seems to be that specific port. I also tried clearing out all of my iCUE settings and that didn't seem to help either. Technically the same could be said for port 6, the one my pump is on. It also refuses to adhere to certain profiles (granted, I would never want my pump to go to 0 RPM anyways, but it is something I tested just to see). It does seem to ramp up correctly based on the Hydro X pump profile, however. Not sure if that is an indication of anything or not. The other ports and fans (all with splitters) seem fine.

I have splitters, splitting 9 LL120s. Honestly, as I experiment more and more it only seems to be port 4 that is having the odd issues. It seems everything else is responding as it should be. Just checked my connections and everything seems good there. I also forced a firmware update and I reinstalled iCUE. Port 4 has 2 fans running on it.

Just a quick update, I went in and tried creating a fixed RPM profile, setting the fans to 0. The one fan that does run at start up, would also not adhere to the fixed RPM. It's almost like the Commander Pro is ignoring all profile settings. Yet, it seems that after the system runs for a while, it randomly will start working and responding again. Are there any other known applications or services that cause issues with iCUE?

Absolutely. Here is what my fan profiles are configured as. I have not ever used HWInfo. I do have Aorus System Viewer installed though, however I don't believe it has ever caused any other issues. Granted I can always uninstall because I don't use it.

Seems the latest updates have broken quite a lot for a number of people. Has anyone had any issues with fan profiles just straight up not working? I have 5 fans and a Hydro X pump and on boot, one of my fans randomly spins up, ignoring its assigned profiles, while the others sit at 0 RPM. After a while, it seems they sputter to life, quite literally, before becoming stabilized and randomly adhering to the profiles again.

I started noticing an odd problem with my fan curves over the past couple days. I currently a Commander Pro with ports 1-5 for fans, and port 6 for a Hydro X pump. Everything has always worked until a few days ago I noticed my fans have not been running consistently per their profile. I would have one fan randomly spin up, ignoring its profile settings while the others sit at 0 RPM. Eventually, after about an hour of the system being on, things seem to 'reset' and all the fans seem to stutter, but eventually work as they should per the Hydro X profile. Any thoughts? See the attached screenshot for what their eventual spin-up looks like.

That would be pretty useful. I'm a software developer myself so I'm pretty familiar with XML. The extension cable I'm seeing that should work comes with the Corsair RGB LED Lighting PRO Expansion Kit, as it seems I will need a male to female 3-pin RGB extension cable that's included for the RGB strips to make the HydroX pump RGB cable reach my CoPro (everything else is daisy chained off of my pump). I'm thinking 30cm to be safe. I currently live in Ohio (USA).

I did have 1 custom curve when I tried creating a dummy Hydro X lighting channel. I will try deleting it and attempt that again . Is this a known issue with iCUE? Seems like the stars have to align for these Hydro curves to appear. I do not have the LED kit. I did see the extensions there though and I think they will work. It just sucks having to spend 40 dollars potentially just to get 1 extension cable.

So I tried to create a 'dummy' Hydro X lighting channel on the commander pro and that didn't seem to work. I'm guessing it absolutely has to plug into the commander pro? My temperature probe is plugged into the first temperature sensor port. EDIT: If that's the case, currently this is not possible for me. The RGB cables on the waterblocks and pump are incredibly short and don't reach the commander pro in my case. Having them reach a lighting node pro is easy because of how small the node pro is. Any thoughts? I saw that you can get custom made RGB fan extension cables but since these are 3 pin , I wasn't sure what my options were.

Currently, my GPU, CPU, and pump are daisy chained and connected to a Lighting Node Pro, along with another RGB hub. The lighting node pro has a channel configured for Hydro X and I can control all RGB lighting. I have all of my fans and the pump PWM, along with an additional RGB hub connected directly to the CoPro. The only fan curves that are available to me in CoPro are the defaults (Quiet, Balanced and Extreme).
