Thanks for the report. Yeah fingers crossed it will work.

Hey! Thanks for posting with a similar issue. A new Commander Pro solved it? My retailer is going to take care of an RMA for me which hopefully will solve the issue! Thanks.

I really appreciate all of your help on this given there is no responsibility to do so or compensation, so thank you! I have a 700W Bronze PSU so the 12v may or may not be great since it is bronze rated, but you are right. I was not under load of any kind and that screenshot was at Idle. Either way, I don't think it is an issue of the fans not having enough power since I am trying to get them lower... Which would require less power and should be capable. In fact I can speed them up with what limited control I have available. I will get a support ticket started for the Commander with Corsair. I also likely have warranty for my purchase with the retailer since I just purchased it recently so I could seek that option as well. In the mean time, I actually ordered a splitter so that I could try putting these three fans that aren't working directly to the MOBO header for direct control, but that kind of eliminates the purpose of having the commander haha. Thanks again for the help. I will see what my options are with Corsair and my retailer.

I just tried a firmware update, forced it to go through and nothing changes. The fans spin up to their 1500-1600 when the commander device gets disconnected to perform the update and then back down when it comes back online. After swapping the rear exhaust fan, and one of the AF 120's the whole system went crazy. Here is what happened: - The rear exhaust fan WOULD not spin. I tried changing it from 3 pin to 4 pin to auto and nothing. It was recognized but would not start. - The three other (yes all three) AF fans slowed down! to where they should be but the one that I swapped showed a speed of 0 RPM. Even though it was clearly at about 800. - I created a new profile to test the fan I swapped to see if I had control over it and it would not move. - And now one of my fans is Lost. Not recognized. It is spinning, but I can't see it in iCue. Not even when switching 3/4 pin/auto. I think it may be my commander unit is faulty? Thoughts? It definitely is not a question of are these fans capable of going slower now. They are. It is something funky going on b/w either the Commander and the fans, or iCUE through the commander to the Fans. EDIT: I am now trying to force a firmware update to get my fan back and the device is not visible, with the update stuck at 0% and it won't budge. EDIT 2: I had to uninstall and reinstall iCUE to use it, the commander was locked up in a firmware update and to get the fan to show up again. It didn't fix anything though. So this is pretty clearly either a Commander PRO is faulty issue, or my iCUE firmware is not recognizing these fans correctly and is doing some funky things. It's like the fan's aren't calibrated right?

I tried but I couldn't find the proper file! That sounds exactly like what my issue is because (again, I could be wrong here) I don't think it used to do this. Do you know which firmware you updated to? or where I could find it?

That is precisely my issue lol It is LOUD. They are in fact the Retail AF 120's that came in a three pack. I Linked them up top and they are virtually brand new so I doubt it is a defect on the fans. I could see one failing but all three seems to be a "feature". I THINK they are a persistent spin fan since they are 3 pin with now PWM management so they go strictly off voltage. But you cant adjust voltage on the Commander Pro with iCUE (I think?). I will try swapping around the fans but I am almost certain it is that these fans have a minimum speed or something is going on software wise. Thanks for the help.

Hello! Thanks for the reply. The 3 AF 120's are simply connected using the fan's connector to the Corsair Commander Pro Slots. They fit fine, just that they are 3 pin fan connectors going to the (potentially) 4 pin headers on the commander. This might sound strange but I feel like they USED to be quieter and slower. In the past couple of weeks (I can't identify anything I have blatantly changed) they have lost the ability to go down below 1300 RPM and I feel like it is due to something on the commander or iCue. OR they actually don't have this ability and I am just paying more attention to it now. Firmware and updates and uninstalling/reinstalling have not helped. The Fan curves are custom and are set to sit about 600 RPM till 55-60ish then ramp up towards maximum when they get to 65-70 degrees. That being said, Even setting the system to a FIXED RPM setting for those three fans, and then putting those to 0 or something lower than 1300 does absolutely nothing. They can only go up to around 1600. So their range is 1300-1600 RPM is. https://gyazo.com/06d65558a7704c78e9ea21fba168c35b The bottom three fans in the stack are the AF 120's. One of them is going off of the CPU sensor as it blows directly into the path of the CPU. The other 2 are on the GPU package Sensor.

Bumping so that I can get some support or discussion on this. Thanks

I am in fact using a custom fan curve, they don't move below 1300 RPM or above 1500 or 1600. Also, the specific fans that are 3 pin are selected to 3 pin in settings. I also have made sure to set the fan curve for those specific fans. This does not change the issue with those fans. Also, the three AF's that are having issues are NOT connected to a case controller, they are in the commander and appear in iCue but it doesn't do anything to their speeds. They can go from 1300-1500 RPM. thank you though for the help!

Hello All, First time post on here and I am having an issue with my fan speeds and not adjusting down below ~1300 RPM. I will provide the best information I can with potential fixes I have tried. Specs are as such: i7 8700, ( air cooled from the Motherboard 4 Pin Fan header) Asus ROG Strix 2070s 32 gb Ram 700W PSU 5 Fans All plugged into the Commander Pro: - 1 SP Fan Over top of the CPU cooler (Working properly and the speed can be adjusted by iCue) - 1 AF Exhaust (Came with the case fan- Can be adjusted with iCue) - 3 AF 120mm 3-pin fans for the case (all of which CANNOT be adjusted using iCue) Link The fans in question cannot be adjusted using iCue and consistently spin at ~1300 RPM, but they CAN be increased to ~15 or 1600 RPM with custom fan curves. The Fans in question are using the GPU Package as the sensor and even with custom fan curves it does not solve the issue. I am looking for a solution to get iCue to make these fans work, OR alternate software, OR a recommendation to get these fans to work. My thought was to use my other 4 PIN fan header (non-CPU) on the Motherboard with a splitter to control these 3 PIN AF 120's, but would that work? Can a 4 PIN header control a 3 PIN fan with modulated speed? Isn't that what the Commander Pro is supposed to do? Thank you in advance for your time and assistance. Cheers,
