Johnny87au Posted April 18, 2019 Share Posted April 18, 2019 Just curious whats the max power limit per port on the commander pro, could i use a 2 in 1 splitter and link two fans into port 1 ? Link to comment Share on other sites More sharing options...
DevBiker Posted April 18, 2019 Share Posted April 18, 2019 The max power per spec is 1A per header and 4.5A overall. That said, 2 way splitters do work fine. 3-way splitters cause issues so as long as you stick with 2 way splitters, you're good. Link to comment Share on other sites More sharing options...

How much do the White LL120's pull running at 2200RPM? Cause i'm using all 6 ports on the pro and if i could use 3 total would save me 3 ports for later use :) Link to comment Share on other sites More sharing options...
DevBiker Posted April 24, 2019 Share Posted April 24, 2019 According to the specs, they'll pull up to 0.3A. Link to comment Share on other sites More sharing options...

Zotty Posted April 25, 2019 Share Posted April 25, 2019 Oh awesome, so i can run 2x no issue right.. I do...... although not supported by Corsair,, so at your own risk.. I am currently running 8 fans on one CoPro.. most i have ran is 9,, and as said,,,, doubles only. we have seen triple splitters pop fan headers Taken from my FAQ thread Not Officially supported but there is no reason why you can not use Fan header Splitter cables on the Commander Pro (note there is a 1A limitation per fan header and a 4.5A limitation for the entire unit including it's MCU and any Corsair RGB Strips you have attached) and I recommend no more than 2 Fans on any one Channel (note, seen plenty of issues when trying to use triple PWM splitters or more). more here http://forum.corsair.com/v3/showthread.php?t=173880 Link to comment Share on other sites More sharing options...

Zotty Posted April 25, 2019 Share Posted April 25, 2019 that would work... thats how mine is... something like this http://i.imgur.com/GH6RjQcl.png the last 4 fans are on headers 5 and 6 Link to comment Share on other sites More sharing options...
hawaiianryan Posted May 13, 2019 Share Posted May 13, 2019 Wish they would have made people aware of the limitations to using only a 2 way splitter (2 fans on one port). Would have saved me a lot of problems. Now I have 2 commander pros that don't work. Funny how the Mini could power 3 fans on one splitter and the Pro can't even do that.

azjim Posted June 6, 2019 Share Posted June 6, 2019 I wish I would have seen this thread BEFORE I purchased the Commander Pro. It lasted about 20 sec in my chassis before it burned up 4 channels with 1 fan on each header. Each fan draws 1 amp. Now the question is do I try and repair it or toss it and look for a different option. Link to comment Share on other sites More sharing options...
Ganjahouse Posted October 16, 2020 Share Posted October 16, 2020 I have a question, I have the Laing DDC 3.25 Pump and it is only powered by a fan cable and it is 18w and 13.2 Volt. Can I connect it to the commander pro's pwm connector? Link to comment Share on other sites More sharing options...
c-attack Posted October 16, 2020 Share Posted October 16, 2020 If that is really powered on a standard fan connection (18w/1.5A), you can't connect that to the Commander Pro or most motherboard headers. Is there no Molex or SATA power cable on the pump? That is how most of them get their power, saving the fan connector as a PWM and tachometer wire speed report.

Ganjahouse Posted October 16, 2020 Share Posted October 16, 2020 It is quite strange, in the description if the molex cable comes out but what I have received only brings the fan power cable. Link to comment Share on other sites More sharing options...
c-attack Posted October 16, 2020 Share Posted October 16, 2020 It's is odd. If I generally search any Xylem Laing 3.25 DDC, I get the version with both that 3 wire fan connector and the 2 wire molex. However, they make a million of these and they can be ordered with modifications. I can't find anything for the part numbers. As far as I can tell, the DDC-1T and 1T plus versions have the dual molex + fan connector. This one does not. It appears to be like this version, which also mentions a molex connector, but not is visible. If this is an actual fan connector and your MB has a "high current" header, that may work. Otherwise, I think you would need to work that through some type of molex to fan adpater and back to the PSU. That would make it run at 100% all the time and DDC pumps get really buzzy at those levels. It would not be a great situation. You might also contact Xylem directly and see if they can clear it up.

Ganjahouse Posted October 16, 2020 Share Posted October 16, 2020 If it is that same pump, all the latest versions of Laing DDC 3.25 come powered with a single cable, the only one that I see different is the DDC 3.25 labeled EKWB Well, my motherboard has 2 connectors with 3A each connector and is specific for pumps. I have no choice but to use some asus software to control the rpm. It's a shame because I would like to control it from the icue. Link to comment Share on other sites More sharing options...
LeDoyen Posted October 16, 2020 Share Posted October 16, 2020 well, the commander pro blows transistors when controlling moderate loads in DC control mode because of the heat dissipated by the output transistor when running speeds lower than 100%.. if you could get your hands on a PWM variant of the pump, it would be a lot easier.. PWM from CoPro, 12V from molex, and done.. Otherwise yes, Asus AIsuite (fan Xpert) will allow you to use the pump socket from the mobo without problems.
