Need Help with Deepcool matrexx 55 (No-RGB)

[Priya Patel]

Hi,
I just bought "Deepcool matrexx 55 (no-rgb)".
Im doing a build on this case, but i confused with two cables of front panel which turn on LED strip on front panel.
There are one Molex (2 pin) and other 4 pin Main Connector.
so i'm using B450 aorus pro wifi, can i controle LED strip light with this motherboard??
or i have to connect it with molex conncector of PSU?

Please I need Help as soon as possible.

Thank you.

If you want to control the front panel RGB lighting from the mobo, do NOT connect that plug from the PSU Molex connector. In the case manual it shows (items 4 and 5) that the default assembly has the cable to the RGB strip (label saying "Main" on the cable) plugged into a matching cable from the front panel switch. You should DISconnect that and take that "Main" cable end and plug in instead to the proper mobo plain RGB (12 VDC system) header. Now, the mobo has several RGB headers, so you need to use the right one. See your mobo manual p. 13 for diagram, and p. 16, item 8 for the LED_C (RGB (RGBW)) header. It has five pins because it CAN also be used for the 5-pin RGBW lighting system although you do not have that. So when you plug your connector in it will only use four pins. Make SURE you align the arrow on the cable connector with Pin #1 of the mobo male header, marked "12 V". Then when you load and run the RGB Fusion utility provided with your Gigabyte mobo it can do all the control of the front panel lighting, and the case LED switch will do nothing.

I don't know if that's entirely correct.

The DIYPC cases that I've used, with a similar (same?) RGB / fan-controller in them have a 2-pin cable going to the front-panel for a selector switch, a cable going to a molex power connector for power, and a 4-pin (minus one pin) that goes to an "RGB header" on the mobo. Although, I think the case I used, that was intended for a 5V ARGB header cable.

Anyways, I read a review that stated, that in order to get the mobo to control the case fan / strip LEDs, you needed to hold down the front-panel button for 3 seconds to switch over to mobo control.

So your instructions above, to disconnect the front-panel connection to the RGB controller in the case if OP wants motherboard control, may be incorrect.

Edit: Take the above with a grain of salt, as I have yet to actually use an RGB controller with a motherboard, only have used a DIYPC case with a vertical LED ARGB strip in the front, as well as a ARGB LED fan in the rear. The RGB / fan controller, had 6-pin headers for the ARGB fans, and they didn't have a separate pinout for power/RPM and RGB control. So possibly they are proprietary to DIYPC cases.

Virtual Larry, you raise a good point. As a general rule, the way that a control mechanism (switch, slider, etc.) mounted in a case pre-connected to devices (fans, lights, etc.) needs to be connected and used is NEVER "standard" - there are NO standards for such things. So the user DOES need to READ the manual for instructions. Unfortunately, some manuals are really poor and don't tell you all this stuff. The manual available for download from the website for OP's case is like that. It shows two drawings indicating two options for how to connect the cable with the "Main" label on it, but no further information. I made the assumption (risky, I know) that this cable connects directly to the RGB lighting device mounted ion the case front and is the only connection to that devvice. So, once that cable is connected to the mobo's plain RGB header, the case's pre-mounted switch system has no impact or role in RGB control. But the manual makes no clear statement on this.

Hi,
Thank Both OF you
Paperdoc and VirtualLarry

Thank for you humble reply and suggestion to guide me.
Curruntly i connceted front LED strip with Molex to PSU, i'm controling light from front panel "LED Button".

I have a RGB Fusion 2.0 and Controlling MOBO and AMD's Stock Cooler Lighting.
I will Return with Quetion, i have to see again that how many pins in MAIN Cable and also have to see PINS on MOBO.

and by the mistake I Plugged "Stock Cooler Fan" Cable to "CPU_OPT". Does this make problem in Future?
also Stock Cooler LED 4-PIN Wire, i plugged it into "LED_Cpu". Cable have Both Side arrow on Opposire side, but i just plugged it, any problem with that in future??

Also I'm Planning to Connect RGB Fan on Back Side - THIS RGB Fan >> Jonsbo FR-601 > https://www.amazon.in/Jonsbo-FR-601-Solar-Eclipse-RGB/dp/B076H1837C

i dont want to control this RGB Fan, so how many Connectors comes with it and where to plug them.?

Thank you.

I suggest you change a few things. Just a note about keeping these things identified correctly. We have used the terms "4-pin connector" and "4-pin fan". The potential confusion comes because BOTH the fan MOTOR and the RGB LIGHTS use connectors with 4 holes (female "4-pin connectors") but they are for different functions. The one for the motor supplies only power and speed control for the motor, and it is about 12 mm wide, with two ridges along one side that are near the holes for Pins 1 and 3 - Pin #4 hole is outside of the ridges. The one for the RGB lights is much wider with 4 holes in a straight line.

Let's look at the MOTOR connectors first. You have not said anything about CASE cooling fans - you've only told us your CPU included a cooling fan that includes RGB lighting effects and hence has a cable for that, too. But you have the CPU fan motor plugged into the CPU_OPT header. That may not make a big difference because both that and the CPU_FAN header likely are pre-configured that same way. BUT it may male a difference for fan FAILURE detection. The CPU_FAN header keeps special attention on the speed of its fan and, if it gets no signal, will send out an alarm that the CPU cooler has failed. So you really should move the fan connector from the CPU fan to the CPU_FAN header, and not keep it on the CPU_OPT header.

Regarding the connection cable from the CPU fan's lights to the mobo LED_CPU header, that is good, so leave it there. As you say, this allows you to control that light system using the RGB Fusion software. If it IS working and you CAN control the lights in the CPU cooling fan using RGB Fusion, then you DO have it plugged in correctly.

Now, to the front panel RGB lights. You have the cable for them, the one with the "Main" label on it ending in a female (with holes) connector, plugged into the cable from the top front of the case. This allows you to control those front panel lights with the LED button on the case. BUT if you move that instead to the mobo's LED_C (five pins) header at the bottom, then you can control THIS set of lights also using the RGB Fusion software, instead of by the LED button of the case. When you plug into that mobo header, the cable will use only four of the pins. Note that the pin on the left (nearest the back edge of the mobo) is marked as the +12 VDC line, and the connector has an arrow marking the +12 VDC hole. Match those up when you plug in. This will leave the right-most pin of the header unused.

Now on to the new Jonsbro FR601 fan you plan to mount as a rear exhaust fan. This unit appears to be wired as what is commonly called a LED fan. Most of those have only one colour of lights in the frame, but this appears to have several. However, the lights are not controllable. They are merely connected in parallel with the motor so they get the same power as the motor, and will light up to their own pattern when the motor is running. So as far a power and control goes, treat this unit as simply a 3-pin fan that requires Voltage Control Mode (aka DC Mode) to control it. It has only a single electrical cable ending in a female 3-pin fan connector. It comes with an adapter to let you connect it to a Molex output from the PSU, but you do NOT need that. Plug this fan into either the SYS_FAN1 or SYS_FAN2 header near the back of your mobo (see manaul p. 13). Now go to p. 28 and make these adjustments for the particular SYS_FAN header the fan is connected to. Set Fan Speed control to "Normal", Fan Control Use Temperature Input to the motherboard sensor (not to the sensor inside the CPU chip), Fan/Pump Control Mode to "Voltage", Fan/Pump Fail Waring to "Enabled".

You mentioned something about to connect the main cable to the top front of the case but where exactly is this? If you can please send a photo

I'm not completely sure what you mean, but I think you refer to the third paragraph that starts with "Now, to the front panel ..." In that user's system the pre-installed RGB lights inside the front panel were fed by a cable ending is a connector with a label on it that said "Main". That connector and cable were routed to the area on the back side of the mobo and plugged into another cable that came down from inside the case top front. That cable came from a lighting control button system mounted in the case to supply power and control of the front lights, and that whole system was pre-installed in the case as it arrived from the maker. My suggestion simply was to change the way those front lights were powered and controlled, by disconnecting their feed cable from that case-mounted front button system and moving it to a mobo RGB header. That would allow control of the lights to be done by keyboard using the RGB Fusion utility supplied with the mobo instead of by the manual button. Probably also it would allow different and maybe more attatcvive displays.
