tennengr Posted July 12, 2020 Share Posted July 12, 2020 I've decided to add a 2nd Commander Pro to allow iCUE control of all 10 QL120 fans. However, I need an additional USB 2.0 port since the 2 motherboard USB 2.0 ports are full with the 1st Commander Pro and the NZXT Kraken Z73 cooler. The Commander Pro literature indicates that the 2 USB connections are pass through connections for USB 2.0. Are there any issues with connecting the 2nd Commander Pro to 1 of these? I assume that there are limitations (amp draw?) to stacking devices through multiple USB pass throughs connected to a single motherboard USB 2.0 port. Meaning my 1st Commander Pro has a spare USB 2.0 pass through and now the 2nd Commander Pro has 2 spare USB 2.0 pass throughs. I can envision adding an iCUE power supply and a couple of Lighting Node Pros with ambient lighting strips. Thoughts? Link to comment Share on other sites More sharing options...
Infin1tum Posted July 12, 2020 Share Posted July 12, 2020 you don't need a second commander to control 10 fans. Just get a powered fan hub. Link to comment Share on other sites More sharing options...
tennengr Posted July 12, 2020 Author Share Posted July 12, 2020 I'm not aware of any Corsair product that controls fan speed via iCUE software other than the Commander Pro. All other products such a Node Pro or Node Core control RGB lighting. Link to comment Share on other sites More sharing options...
DevBiker Posted July 13, 2020 Share Posted July 13, 2020 A powered fan hub is a "dumb" device and allows you to put multiple fans, controlled as a single unit, on one header without having to worry about the power (as it has it's own power source). Typically, they will get power from SATA. The PWM signal comes from the CoPro and it reports the RPM of one fan. From the CoPro's 'perspective', it's one fan. But it's actually multiple fans, controlled together. Link to comment Share on other sites More sharing options...
tennengr Posted July 13, 2020 Author Share Posted July 13, 2020 Much appreciated ... thx. Any suggestions on a fan hub that I should purchase? I assume that it must have SATA power and then must be connected to the Commander Pro. Where would it connect to the Commander Pro? Link to comment Share on other sites More sharing options...
Infin1tum Posted July 13, 2020 Share Posted July 13, 2020 (edited) they are pretty much all the same - i'd even say they come from the same factory in china. any generic hub you can find available on amazon will do. generally, they have a sata power connector, 6-10 or even more PWM headers for your fans and one PWM line that connects to the Commander for rpm control. Keep in mind, as DevBiker mentioned, all fans connected to the hub will basically be a single unit - so same speed. I have all my radiator fans connected to one because they run the same speed anyways. my case fans are connected seperately to my Commander.
