Lifescayper Posted October 29, 2018 Share Posted October 29, 2018 Hello, I am hoping someone can help me out with this. I bought the Obsidian 1000D, it came with a Commander Pro and I wanted to control my fans with it. So far I had 3 different experiences: a) All fans just work b) Sometimes some fans don't work but the rest are fine c) All work and then some just suddenly stop to work I am using both softwares the Corsair Link and the iCUE. My setup is as follows (connected fan bundles to cmd pro): Commander Pro -> Connection1: 3x Noiseblocker NB-eLoop B14-2 140mm -> Connection2: 2x Noiseblocker NB-eLoop B12-1 120mm -> Connection3: 4x Noiseblocker NB-eLoop B12-3 120mm -> Connection4: 4x Noiseblocker NB-eLoop B12-3 120mm Experience 1: When I first started to build my new rig, everything worked fine during the installation of windows and new software. Experience 2: After I was done and placed the case from my table onto the floor and booted I noticed Con3 and Con4 not to work - though they did just 5 minutes before, when on the table. So I reconnected them on a different port on the commander and they worked again. Experience 3: I installed a media player, which caused window to reset "default applications" to their default values - during which I noticed that Con3 stopped working In iCUE it only shows me 2 fans(connections) running, even though actually 3 are. Con4 is simply gone. Should I be able to see the commander pro in any software? Link or iCUE? I attached 3 files, showing my link and iCUE Thanks for the help!

DevBiker Posted October 30, 2018 Share Posted October 30, 2018 Uhhh ... that's far too much to put on a CoPro. You've probably blown out the fan headers. The entire CoPro can only take 4.5A for ALL of the fans (That's a limit of the SATA connection). You've got a total of 14 fans on the CoPro. That's likely going to go over that, at least at startup (which is a 12V/full power burst). Now ... officially, Corsair does not support the use of splitters on the Commander Pro. Unofficially, many of us are running 2-way splitters just fine ... 3 way splitters is almost guaranteed to cause issues. I don't think we've ever seen anyone try 4-way splitters but I wouldn't expect it to be good. Link to comment Share on other sites More sharing options...

Hey, thanks for the help - I was thinking the same, though when I originally planed my fan layout I did the math and it all looked fine. Anyways, I removed Con3 and Con4 from the Commander and connected them directly to the mainboard - so far so good. Cheers Link to comment Share on other sites More sharing options...
