Question CoolerMaster Cosmos C700P RGB Query

[racesmith10]

I purchased the Cooler Master Cosmos C700P cabinet a long time back and have been struggling with using it with my ASUS x670E Hero Motherboard's Aura Sync (Armory Crate) software.

I Connected the Cosmos 4-pin Female RGB connector from its CM Control HUB to the proprietary 12V 4-pin RGB connector in the motherboard.

The Cosmos C700P RGB controller hub controls all the front IO LED and the cabinets' RGB Strips.

Problem 1: Using Asus Armory Crate, apart from standard colors when I ask it to change to orange, it shows green.

Also to note, the website states these are RGB-led panels, and should be connected to the 12v RGB header in the motherboard.

Although Armory Crate detects this as an Addressable Header. As far as I know, Addressable headers are 5V and shouldn't be connected to a 12V socket. Is this why I cannot get the full RGB spectrum? Curious to know.

Am I missing something, kindly help 😌

The fact that, "Armory Crate detects this as an Addressable Header" suggest strongly that you have plugged the cable from the case lighting hub into the wrong mobo header. That mobo has BOTH types of lighting headers. It has THREE of the 3-pin Addressable Gen2 headers (see manual p. 1-17) of which ONE is at top front. And right next to that one is a FOUR-pin AURA Sync RGB header (p. 1-19). That 4-pin one is the one you must use for this lighting type. FURTHER, note that the header labels show the pin on one end marked as the +12 VDC power line. The female connector from the hub cable will have the hole on ONE end marked. THAT MUST be plugged into the pin for 12 VDC. So check that the plug is turned the right way.

Lastly, note your case manual on p. 19 at the bottom on how to use the case's three RGB Controller buttons at top front. To get the mobo to take control of case lights you must push the M/B button. You may need to do this every time you boot up - the manual is not clear on whether or not this setting is saved.

Yep I connected to the Aura RGB header, and the 12v pin is rightly aligned with the motherboard 12v pin. Here's a picture.

I feel it's the Cooler Master Controller that's not working properly.

Here's a video for reference:

Even though it's able to give out Red, Blue, and Green colors from the LED strip, when I am asking it to mix a certain color as in Orange, usually the RGB color spectrum should have been 255 of Red and 100 of Green, its unable to generate 100 of green.

If it was my motherboard or the Aura Sync Software then how come it is giving Red, Blue, and Green from the 12v RGB Header.

All I am saying is, if it is possible to get a replacement for the Cooler Master RGB Controller (c2055-02-sj) I would be able to verify properly.

Any help is appreciated.
Regards

Have you contacted Cooler Master?

Have you contacted Cooler Master?

Yep, I did submit a ticket. Their response time is too long. Plus they are suggesting its Armory Crate, try uninstalling and installing their legacy Aura Sync utility software. Tried all, but it hasn't worked so far.

Well, most motherboard RGB software sucks so they might be right. You could also try something like Signal RGB or Open RGB and see if it handles it any better.

Okay will give it a go, btw would you be able to help me understand what causes RGB to malfunction? I recorded a video explaining what's going on with the RGB strip. Here's a link to the video

In this case there is 1 of 2 things happening IMO.

1. The RGB software is not sending the correct settings to the motherboard on some custom colors.
2. The RGB controller is not interpreting the data being sent by the motherboard correctly.

One other thing you could try is that it looks like the controller has multiple outputs. Have you tried a different output to see if the RGB strips do anything different?

Haven't tried it yet, the controller only has 3 output headers. Heres' the pic

 

[racesmith10]

Thank you so much for your time, really appreciate it.

Just now I tried swapping out the headers one at a time, didn't work like it should be. I am guessing the controller is not interpreting the data correctly. I am going to try connecting a brand new led strip to the controller and see if this happens. If not its the case RGB strip, else its definitely the controller

I'd still try the Open RGB or Signal RGB software too. They are free I believe.

Tried OpenRGB, didn't find success

So I tried switching the RGB connector on the controller from RGB 1 to 2 and 3, still the same.

What do you think might be causing the controller to not interpret the data correctly?

That's just my thoughts. It appears to me that the "controller" doesn't do much other than switch from "motherboard control" to "case control" and also provide the colors under "case control". It should just pass on the information if in "motherboard control". But I don't know that is how it works for certain. It may do other things.

Did you have an RGB strip that can be plugged directly into the motherboard and test if that one works correctly? That would certainly narrow down the issue.

 

[Paperdoc]

The other form of testing would be this. Unplug ONE of the lights attached to the case board. Unplug the cable from that board to the mobo 4-pin plain RGB header and plug JUST that one light strip into the mobo header. Now see what that one strip can display. If it displays things correctly, then you are sure the WRONG displays are being generated by the BOARD. BUT if the single strip displays the same wrong colours, just like when it is part of the board's output group, then the MOBO header is sending out wrong signals.The result certainly should satisfy the Tech Support people of whichever faulty unit (board or mobo) is to blame.

Gotcha,
Yep, I ordered a 5050 RGB strip on Amazon, and would receive that today. Will connect it to the motherboard to see if it works.

I would have done that but the RGB connectors from the Cabinet are JST 2mm format and the motherboard RGB header is at a different dimension. I purchased an adapter to run a random 5050 RGB strip directly to the mobo just to test if its the motherboard connector that's causing this issue in the first place.


Do you know any adapter that can connect the case RGB connector directly to the motherboard 4pin RGB header?
Then I could do tests with the LED from the cabinet directly

RGB and ARGB are different. RGB is 12v, usually 4 pin, ARGB is 5 volt, generally 3 pin.

Sorry...senior moment

ARGB is 5V, but 3 pin. RGB is 12V, 4 pin

Dur...what he said.

 

[racesmith10]

lol no worries.

I did run through connecting an external RGB strip on the Mobo vs running it via the controller. Seems like the controller is malfunctioning. Mobo rocks, Controller sucks.

Going for RMA

Good! You have identified the problem item clearly.
