Alright, I did some research, and have some results.
First of all, IMHO SP120 RGB are not UCS1903. I've check documentation for it and this uC requires 800kHz oscillator. I've checked on oscilloscope the signal from LNP and it is oscillated at 400kHz.
The second thing, if the LNP is connected to rgb hub, oscillation is rock solid. If I connect this fancy 3 button controller to the hub, oscillation varies from 400 to 420kHz.

And the last thing, which is probobly the best example of WTF:
In my configuration, fans enclosed with crystal case were connected to the rgb hub to ports 1-3.
My new sp120 fan, was connected to port 4. All were blinking.
But if I connect a spare fan to port 1 on rgb hub, IT WORKS, but only this one. Other tree fans blink. I do not have another spare SP120 for tests, but I suppose, that it will work like a charm at port 2 of rgb hub.

@red-ray, you've bought 4 sp120, am I right? They are not from crystal or other case ;).

The SP120s I have are not from a crystal or other case and the numbers printed on them all are:

12V DC 0.30A
CO-9050061-WW
RWF0016
MADE IN CHINA


What part numbers are your fans?

All 4 fans are CO-9050059-WW. Even a spare one.
No logic at all :/.

Idea Did Corsair mess up and fix this with a later revision?

  1. Why are your fans CO-9050059-WW when mine are CO-9050061-WW? 3 pack vs. 1 pack I guess.
  2. What are your RWF0016 type numbers?
  3. If you connect just one of the fans that came with the case what happens?
  4. I am starting to wonder if Corsair messed up and fixed this with a later revision.

1. I don't know. I bought the case and a fan in large polish internet store. They could stay at stock for a months.
2. The same (4 fans). All spec is the same (voltage, current).
3. Blinks (all 3 fans from case connected to port 1 of the hub).
4. Probably, but the same part number and RWF0016 denies this.

It is awkward. My conclusion is that Corsair in crystal cases is not using the same SP120 RGB fan, that can be bought separately. Maybe these fans did not meet some internal requirements. I suppose Corsair will not answer it :).

Idea It's RMA time

Given three are faulty and one works I feel you should request an RMA

But for what? A case or LNP ;). Please be advised, that these 3 faulty fans are from crystal case. I dont think I could rma these fans only.
Anyway. I will compare a static effect from LNP and rubbish controller from a case. For me it looks like there are some pulses missing (not all control packets goes to fans).

That's how it looks right now

Arrow Start the RMA for the whole case

Start the RMA for the whole case and say it's just the fans that are faulty.

With a bit of luck they will just send you 3 working fans and you won't even need to return the faulty ones.

Interesting stuff guys, nice detective work.

I've gotten the attention of Brian in Corsair support. I created this video, which shows my issue: https://1drv.ms/v/s!AgU5kl-QvwZmgqBNwuQOF6_AoUbocg

A replacement LNP is already on the way - and Corsair are replacing everything else in the setup - the 6 SP120 fans (3 from the case, 3 I purchased separately as individual units), the RGB hub from the case, and they want me to ship my units back to them so they can test them.

I'm curious if I set this up with just the 3 fans I purchased separately, and not the ones from the Crystal RGB case, if it works as expected. I haven't tried that. I'll do it later on today and get back to you.

At least we've got their attention, they are aware that there is clearly an issue, and they are now actively taking steps to get to the bottom of it.

Thanks all,
Will

Question Is CL 4.7.0.77 double reporting motherboard fans?

My SP fans are nothing like yours and it will be interesting to see what happened when you connect the 3 additional fans to ports 1 + 2 + 3 of the hub.

Is CL 4.7.0.77 double reporting motherboard fans? It's hard to see of the video, can you post the CL4 [Home] tab + the SIV [Cooling Status] panel?

As you saw my video, the overall effect is exactly the same.
Please try your separatelly purchased fans to connect to the first port on a hub. If it works, try another. If you test 3 of them, and all will work on first port, leave one in it, and connect another fan to port 2. The same procedure with 3rd one.

The problem appears to be with the 3 fans that came with the Crystal 460x RGB case. Currently I have the 3 separately purchased SP120 fans wired up to ports 1, 2, and 3 of the fan hub, and they are working as expected. Trying now to determine if it's just 1 of the 3 SP120s that came with the case that is causing the problem, or if they are all problematic.

Will get back once I've finished my testing later this afternoon and will post another video.

It's good to know, that we have similar results.

I've tested case fans, tried to connect each of them to port 1 and all free are faulty. So I'm rather sure that for cases, Corsair uses a worse quality (more problematic fans).

I'm wondering if someone from Corsair reads this topic ;).

Wink SP RGB fans that come with the cases must be early revisions

I suspect the SP RGB fans that come with the cases must be early revisions that have issues and the SP RGB fans that work are a later revision that have been fixed. I don't know what the difference is or if it would be possible to adjust/frig the LNP firmware to make them both work, only Corsair could know this.

I will be interested to know hear Corsair have to say.

The problem is definitely all three of the SP120 fans that came with the Crystal 460x RGB case. Below is a link to another video.

The video starts off with just 3 fans connected to the LNP via the fan hub. The top fan in the front (one of the originals from the case) is connected to port 1, and the 2 illuminated fans in the rear are connected to ports 2 and 3 (these are ones I purchased separately). You'll notice at the beginning the weird flickering behavior on all 3 fans.

Then I unplug the fan in the front and replace port 1 with the 3rd fan in the back, and the 3 fans in the back immediately start working normally.

Then I attach the 3 fans in the front to ports 4, 5, and 6, and the three fans in the front flicker but the ones in the back continue to do so.

Here's where it gets weird. I then unplug the fan in the rear that is connected to port 1 and replace that with one of the fans in the front, and it causes all of the fans to flicker.

This happens no matter which fan in the front is connected. So basically the front fans (purchased with the Crystal 460x RGB case) never work right when connected to the LNP, and the rear ones do (purchased separately), AS LONG AS they are connected to a lower port number on the RGB fan hub than the ones in the front. If they are connected to the RGB fan hub in a port higher than the front fans, all fans flicker.

Here is the video: https://1drv.ms/v/s!AgU5kl-QvwZmgqBXP4CZkKFjr5K5Gg

I suspect Corsair will replace the 3 fans that came with my case.

If anyone wants to refer to my case # when creating a case of their own, it is ticket # 6922867.
