The Commander Pro (CoPro) LED won't light up. No worries there. Get windows and Link installed and configure the logo (as an SP fan, IIRC ... check the RGB FAQ linked in my signature below). If it still doesn't work, come back here and we'll try to get you sorted.

It's not fixed yet. It is still on the radar. Also, we've learned that it apparently doesn't just affect the Commander Pro's USB hub, but at least one other internal USB hub has issues with the AsMedia chipset.

Yup. The Pro coolers are SATA powered so that's all that connection does. it has no other purpose in life.

Well, the 115i PRO is 280mm, the 150i PRO is 360mm. But ... regardless of which one you wind up getting, both have a fan connection that connects to the CPU Fan header. It serves no purpose except to provide a fan tach signal (RPM) to the motherboard so that you don't get a CPU Fan warning from the BIOS. There would be no point in connecting it to the CoPro and no advantage to doing so.

Because USB 2.0 is limited to 500mA. That's not enough to power so much as a single LL fan (620mA). SATA provides up to 4.5A.

Use Afterburner. Precision XOC has been causing all kinds of issues with Link lately. Also, Gigabyte may have a specific tool to do the task.

Honestly, we don't have the numbers on them. And while I know that there seem to be a lot of those on the forum, keep in mind that folks with coolers that work and don't have any issue don't come posting on the forum about how great the experience is ... but the ones that fail do. There's always some percentage of coolers that fail before their expected lifetime. And Corsair has a five year warranty to cover those cases of premature failure.

Nice! I've also been thinking about how to do custom cables that, say, have 3 ML fans on one port that you configure like an HD fan. This actually gives some cool effects across the fans. Now that we have all of the pieces, there's a lot of interesting stuff that can be done with some wire cutters, wire strippers and crimpers. :headbang:

Can you please fill out your system details? Are you running any other monitoring/control software? It's hard to guess what you may have running without the system details. We've actually seen a number of issues caused by other vendors' control programs.

Have you removed the fourth LL fan to see if things "come back"? From there, also make sure that you check all of your connections and make sure that they are tight. Even if you didn't mess with them, you were in there and it's possible something was disconnected.

No worries, dude. That's why the forum is here. The third wire that should be missing from one of the cables reports the fan speed (RPM). You should only have this reported from a single fan. If you have two RPM signals coming down that 3rd wire, it'll cause some major issues with fan speed reporting. Pins 1 and 2 are for power (+ 12V). Pin 3 is for RPM. Pin 4, which needs to be on both, is for the PWM signal.

@Popza: Does the Airflow have a 3-pin or 4-pin RGB LED header? IF it's 3-pin ... I wonder ... can be it added to the end of an LED strip chain? (If 3 pin, it should be possible) It may be possible to use a custom cable to add it to an RGB Fan Hub as the last in the chain and configure it as an HD fan.

One challenge that I've had with my RGB fans is placement of the RGB Fan Hubs. This is especially challenging in a large case (such as mine) and exacerbated by a desire for some manner of cable management - which means that cables cannot take the shortest, straightest path between point A and point B. Extensions could help with this. A lot. Sometimes just an extra 30cm or so would be more than enough. But while the RGB strips come with extension and connector cables, the RGB fans do not. I've looked and extension cables can be bought at ModDIY ... $9.99 for a measly 10cm. That's less than 4 in.! Those cables are so short that it's laughable. 1: Connectors The Corsair RGB Fans use a Molex 50-57-9404 4 circuit female socket connector. This is available from DigiKey for $0.27/each. These will connect to a Molex 70107-0003 4 circuit male pin housing connector and available for 0.57/ea. The connector for the cable between the Lighting Node Pro/Commander Pro RGB ports and the RGB Fan Hub uses Molex 50-57-9403 female socket connector on both ends. For this cable, only 2 of the 3 connectors are filled. Pin 1 (where the arrow is on the connector; this is +5V power) is not connected on either side. This is the same connector that is used by the RGB LED Strips (except pin 1 is connected for this). If you do wish to make your own RGB LED Strip extension, the other end will be a Molex 70107-0002 3 circuit male pin housing connector. 2: Pins The connectors are only one part of the equation. You also need the pins. The cables are crimped to the pins and then the pins inserted into the connectors. For the female socket connector, you need Molex 16-02-0102 female crimp connector (0.15) (Thanks to BobKabob for figuring this out ... this was essential in getting me going in the right direction.) On the other side, this will connect to a Molex 16-02-0114 male crimp terminal (0.25 / ea). All told, the connectors and the pins for a single cable come to a whopping $2.24! Note that these connectors and pins can also be used to repair RGB fan connectors if you've managed to disconnect the connector from the cable. 3: Wiring The Corsair cables are 24 AWG twisted strand cables and look like they are probably tin; I doubt aluminum and it certainly isn't copper. Maybe tinned copper? Fortunately, 24 AWG wiring is really, really easy to come by; it's everywhere. That said, you can get cables that look very, very much like the stock Corsair cables from ModDIY. I also had some RGB 5050 extension cables laying around that I don't use anymore because Asus Aura is sooo 2016 ... while copper (so lower resistance), they are also 24 AWG. Here's another thought ... Cat 5 ethernet cables use 8 24 AWG cables. This means that, potentially, you could have a single extension cable for 2 fans! Oh, the possibilities are endless. 4: Tools You'll want a crimping tool for these. Yeah, you could probably use needlenose pliers and get it done but the results would likely be less than ideal. Search for "Molex Crimping Tool" ... these are different from other crimping tools for larger gauge wire. You'll also want a precision wire stripper that will cleanly strip 24 AWG wire. These, of course, are reusable. From there ... you strip and crimp, strip and crimp ... then slide the crimped connectors in to the housing. The biggest thing that you need to be careful of is to make sure that the wires are connected to the correct cables (straight through connection).

What type of fans are the 3 front fans? What is their current rating (this should be on a grey sticker on the fan). The Commander Pro's fan headers, like most fan headers, are limited to 1.0A. If you go over that ... Also, the CoPro is limited to 4.5A overall. So you need to be aware of the current load for ALL of the fans that you have connected to the CoPro.

That's actually not entirely accurate. Can you use splitters? Yes. Is there a 4.5A total limit on the Commander Pro? Yes. But there is also a 1A limit on each fan header. So you must be aware of the current draw of each fan, each header and the Commander Pro over all.

The CoPro actually has a NoPro as a component. It's the exact same in each. If both a NoPro and a CoPro are doing the same thing, then it's most likely a software issue. The LLs are, btw, software controlled. The crazy thing is ... it's almost like you are missing LEDs in the chain. What happens if you put fan #1 on fan #6?

There's no reason that you would want single rail. http://www.overclock.net/forum/31-power-supplies/761202-single-rail-vs-multi-rail-explained.html [ame] [/ame]

The ML fans definitely have better performance. The LL fans definitely look better. For quiet ... hmmm ... probably pretty close. Both are very quiet but the ML fans do spin faster. That said, the LL fans would like be enough ... you might to talking about a difference of 2C (guesstimate) in cooler temperatures ... so from maybe 35 to maybe 37C.

Yes! That would be good. What I wondered was about the power. BUT ... the LED strip packaging doesn't tell us the current requirements. BUT ... based on the current requirements for the LEDs on the LL and HD fans, we can estimate about 0.04A per LED ... so 0.4A per strip. That's 1.6A for 4 strips, 3.2A for 8. If you do two strips of 6, you're looking at 4.8A, which is more current than is provided for over the SATA connection (4.5A) and leaves nothing for the Lighting Node Pro's processor. Five strips per gives you a total of 4.0 A even. So that's a possible winner. Now ... if the configuration was "smart" enough to do on the fly current requirement calculations based on the devices attached and allow you to leverage that current how you wanted to, then you could have a 10 strip connection on one port and an LED fan hub (which takes no current from the NoPro) on the other port. Or ... 6 and 4 or 8 and 2. However you arrange it for a total of 10 strips max for each NoPro.

But your Link screen and diagram only show SIX-TEEN. Not Twen-Tee-Four. Where are the missing eight?

Yes, this will work. This is actually how I test fans externally before putting them in my case.

Hmmm ... yeah, don't have CUE. :( I my foolish youth, I got Razer for my keyboard and mouse since Corsair didn't have a single application to control keyboard, mouse and cooler (which was all I had at the time). It'd be really awesome if Link and CUE were combined into one single RGB and control app to rule them all with an SDK/public API. :cool:

Definitely agree. Actually, what would be even cooler is if Corsair provided an API that community developers could plug in to and then do this kind of stuff. It would take a huge burden off of their development team and encourage community involvement. But that's just my $.02 worth.

As with the OP, please try rearranging them on the hub to see if it's just a single fan. Also, as I discovered last night, make sure that your wires have a bit of slack in them. If they are too tight, it can also cause issues.

Ugh. That's icky. Personally, I'd really like to see these cables available separately as well as extensions for the fan RGB connectors.
