hifiuff Posted October 6, 2018 Share Posted October 6, 2018 Hi there, I wanted to make sure I got my information right before ordering the fans / fanhubs for my upcoming 9900k+2080ti build. For cooling, I have decided to go with ML pro RGB fans. So, I will need to control power and lighting for a total of 12 fans : 8xML120 pro RGB (for two 480 XE from EK) and 4xML140 pro RGB (case fans intake, in an Enthoo Elite). It's my understanding I would need two Commander pros and two RGB fan hubs. Here are my questions: - Would populating all power sockets from both Commander pros go over their respective power limit of 1A I think? - Would I need two USB 2 headers from my motherboard or would one suffice provided it won't saturate the available bandwidth of this single USB2 with two daisy-chained commander pros fully populated? - Can I mix two different sizes (120 and 140 mm) but from the same line of fans (ML pros RGB) on a single RGB hub or do I need one RGB hub for the 140s (4 fans) and TWO RGB hubs for the 120s (8 fans)? In short, do I need two or three RGB hubs on top of the two commander pros? - Is it possible to manage the fans on one commander pro so that some fans connected to it will act as PWM fans and some others just DC, or do I have to use one commander pro for everything PWM and another one for DC? If you feel like I should know anything else before ordering, please let me know! Thanks in advance to everyone for their answers! Cheers! Link to comment Share on other sites More sharing options...
c-attack Posted October 6, 2018 Share Posted October 6, 2018 (edited) It’s 1A per fan header, but 4.5A for the entire device. You won’t get anywhere near that with the ML-RGB and their very low fan current. The lighting current will go through the separately power RGB hub(s). Yes, you can daisy chain the the two C-Pros. It would be a disaster if you could not. USB 2 internal is getting hard to come by. Yes, you absolutely can mix 120/140/180/200mm fans of any type on the C-Pro for fan power and speed control. It is only the RGB Lighting Hub that must be uniform in Corsair fan model (ML, LL, HD) but you can still mix the 120/140 in any combination. Still need 2 hubs for 8 fans though. Any combination you like on DC/PWM mixing. I am doing it now with 4 PWM and 2 DC. It feels like there is always something more to know, but it looks like you have done your homework. I’ll see if I can link some of the guides.
